In the context of Article 31 of Regulation (EC) No 178/2002, EFSA was asked by the European Commission DG SANTE to provide technical assistance in the field of plant health as regards the regulated harmful organism Xylella fastidiosa, as per letter to EFSA's Director dated 30th June 2016 (Reference ARES(2016)3126989).
EFSA was requested to further specify and update the host plants database of X. fastidiosa available in 2016 (EFSA, ) taking into account the different X. fastidiosa subspecies and strains (with particular reference to the European isolates), with the inclusion of information on non-susceptible plants and varieties and negative results of diagnostic tests when available. EFSA was requested to maintain and update this database periodically and to make new releases available on the EFSA website, together with a scientific report. Such report should specify the list of plants confirmed to be infected by at least two detection methods in field conditions or via vector transmission under experimental conditions and be published at least annually, or according to needs following agreements between EFSA and the European Commission. Such request is for the period 2016–2020.
Interpretation of the Terms of ReferenceFollowing this request, European Food Safety Authority (EFSA) delivered in September 2018 a renovated and updated database of host plants of Xylella spp., taking into account both species of the genus Xylella (X. fastidiosa and X. taiwanensis) (EFSA, ). A systematic approach was applied according to the EFSA guidance on systematic literature review (EFSA, ) and detailed information on host plants, infection methods, geographic location, pest genetics, detection techniques and host status were collected from more than 850 references. The data structure of such database was renewed in order to improve consistency and transparency, and raw data and interactive reports were published in Zenodo in the EFSA Knowledge Junction community and in Microstrategy platform, together with a Scientific Report.
As per Terms of Reference (ToR), EFSA was requested to maintain and update the Xylella spp. host plant database periodically, and to publish new releases online together with a report. This Scientific Report provides an update on the database of host plants of Xylella spp. published in 2018 (EFSA, ). An extensive literature search was conducted to retrieve recent publications on the topic and new informative data on host plant species of Xylella spp. were collected. Such report provides information on the literature review and a detailed view on the currently known host plants of Xylella spp.
Data and methodologiesThe methodologies developed for the Xylella spp. host plant database published in 2018 (EFSA, ) were applied in this report.
The process was divided in the following steps:
- Extensive literature search to identify relevant references.
- Selection of studies based on title, abstract and full text.
- Data extraction of relevant information.
- Update of some data already inserted in the Xylella spp. host plants database published in 2018.
- Data analysis and reporting.
The review question ‘Which plant species can host Xylella/Xylella associated disease?’ was broken down into key stages using the P/O conceptual model described in the EFSA systematic review guidance (EFSA, ):
- Population of interest (P)
The population of interest is that of plant species, worldwide.
- Outcome (condition of interest) (O)
The outcome (condition of interest) is that of Xylella spp. infection.
Two main elements were considered for the extensive literature search: the sources of information (Table ) to be consulted and the search strategy (Table ).
Information sourcesThe search strategy was run in all databases listed in Table via the Web of Science (Clarivate Analytics) and Scopus platforms with no language or document type restriction.
Sources of information
The syntax of the search string, developed for the Xylella spp. host plants database published in 2018 (EFSA, ), was adapted and run into each platform databases listed in Table on 30 June 2019. As the scope of the search was to retrieve references published after September 2017, the selected time span was from 30 September 2017 up to 30 June 2019. The search strings and the number of retrieved references are shown in Table .

The collected records were downloaded and imported into an EndNote X9 library (Clarivate Analytics). Duplicates were removed using EndNote X9 and the remaining references were uploaded on DistillerSR online together with the full texts in portable document format (pdf).
Nine additional documents containing relevant information were obtained from research groups, personal communications of experts, EFSA Horizon Scanning for Plant Health and Europhyt outbreak notifications (accessed on 15 October 2019).
Study selectionThe collected references were screened for relevance in two steps:
- Title and abstract screening.
- Full-text screening of the references that passed the first step.
Inclusion/exclusion criteria were applied in each step and two reviewers worked in parallel screening the references.
The first step required the reviewers to answer two questions, listed in Table , considering only title and abstract of the references. The aim of this step was to select only references presenting original research data on Xylella or Xylella-associated disease.
Inclusion/exclusion criteria for title and abstract screening
| Question text | Type of answer | Answer text | Exclusion criteria |
| Is Xylella/a Xylella-associated disease/a Xylella synonym the topic of the study? | Only one of the possible alternative answers can be selected | Yes | Included |
| No | Excluded | ||
| Is it a primary research study? | Only one of the possible alternative answers can be selected | Yes | Included |
| No | Excluded | ||
The references that passed the first step were submitted to the full text screening. This second step required the reviewers to answer to four questions (Table ): three of them are descriptive (neutral) whereas the fourth has an inclusion/exclusion role.

Some information already included in the Xylella spp. host plant database published in 2018 were updated, with the purpose of increasing accuracy and consistency of the database itself.
References containing X. fastidiosa strains for which the subspecies was not reported in the publication were cross-checked with other references in the attempt of identifying the subspecies to which the strain belongs. In some cases, the author of the reference was contacted to ask additional information on the genotyping of the strain. Whenever the subspecies was identified, it was inserted in the related record and a comment was added in the genotyping comment's column.
The section on geographical coordinates have been modified and updated. Column ‘Location’ includes the administrative location description according to NUTS (Eurostat, for EU countries) or GAUL (FAO, for the rest of the world) territorial unit nomenclature and more precise administrative information if available in the publication. Additional information reported in the publication, such as the research centre name or the experimental field station where the study was conducted, are specified in the new column ‘Additional Location’.
The geographical coordinates were inserted only when explicitly reported in the publication. Other geographical coordinates previously present in the database and inferred from different sources have been removed for consistency with the related documents and for avoiding misunderstandings in relation (e.g.) to extrapolated geographical features. For further information on the origin and on what exactly those coordinates are referred to, the publication should be consulted.
Records present in the update published in 2018 and containing information that have been afterwards updated (such as from Europhyt notifications, or from ongoing artificial infection experiments) have been modified with the most updated information and results.
Data warehouseA harmonised data model has been established to collect data on Xylella spp. host plants. The aim was to establish a harmonised data flow for the collection and the collation of an extensive literature review generated data in the plant health domain. Data are stored in EFSA Scientific Data Warehouse (S-DWH), after that an ETL (Extract, Transform, Load) procedure is applied in order to harmonise and calculated the statistics.
Data managementThe collected data have been submitted to the EFSA Data Collection Framework (DCF). DCF is the upfront system in the EFSA pipeline of data collection tools and allows a first step of harmonisation against the EFSA controlled reference terminology (aka EFSA catalogues). Data have been then included in the S-DWH by means of a standardised Extract Transform Load (ETL) procedure and they have been further analysed and managed to generate needed statistics.
Data are available as interactive reports on the Microstrategy platform at the following link:
Raw data and related metadata are published in Zenodo in the EFSA Knowledge Junction community, this report refers to version 3 (
Data reporting was designed to distinguish the Xylella spp. host plant species, based on the number and type of detection methods applied for each finding. Different combinations of detection methods were considered:
- Plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture) or positive with one method (between: sequencing, culture).
- The same as point A, but also including microscopy: plant species positive with at least two detection methods (among: microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture) or positive with one method (between: sequencing, culture).
- Plant species positive with at least one detection method (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture).
- Plant species positive with at least one detection method including microscopy (microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture).
- All positives plant species reported, regardless of the detection methods (positive records but without the detection method specified, symptom observations, microscopy, symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing, culturing).
The extensive literature search was conducted on 30 June 2019 on Web of Science and Scopus platforms and 429 references were collected. Duplicates were removed and 262 references were uploaded in DistillerSR and screened for relevance. Results of the screening process are shown in Figure .
In the first step, i.e. title and abstract screening, 109 references were excluded either because they do not focus on Xylella or Xylella-associated diseases and/or they are not primary research studies. The selected 153 references were subjected to the second step of the screening process, i.e. the full text screening. Sixty-seven references, in which Xylella spp. is studied is association to a host plant (i.e. in vivo), were selected and informative data listed in Table were extracted.
Nine additional references retrieved through personal communication of experts, EFSA Horizon Scanning for Plant Health and Europhyt outbreak notifications and containing informative data were included in the data extraction.
Unconfirmed studies
Compared to the previous version of the database, two additional publications and one single record were considered unconfirmed/dubious. Those unconfirmed studies are included in the data extraction but excluded from the data analysis.
The paper of Li et al. () reporting experimental infection of Vitis vinifera plants was considered unconfirmed/dubious because, as stated by the EFSA PLH Panel (), an aggressive inoculation procedure was used, making difficult to discriminate between stress induced by the treatment and the disease caused by the pathogen itself.
One record regarding a positive PCR result in one Quercus pubescens plant artificially inoculated by X. fastidiosa subsp. pauca strain CoDiRO was considered unconfirmed/dubious as the publication reports that further confirmation tests still need to be performed (Technical report of POnTE and XF-Actors, ), but no updated results have been published so far.
The paper by Naqvi et al. () reporting the presence of Citrus plants affected by Citrus variegated chlorosis in Pakistan was considered unconfirmed/dubious as the presence of X. fastidiosa and its related citrus disease has never been confirmed in this country.
Update of records already included in the database published in 2018The records already included in the database published in 2018 (EFSA, ) and for which no X. fastidiosa subspecies was assigned to the strain reported in the publication were cross-checked with the references cited in the publication and/or the author of the article was contacted in order to identify the X. fastidiosa subspecies. Whenever the subspecies was identified, it was inserted in the related record and a comment on the source of information was inserted in the genotyping comment's column. A X. fastidiosa subspecies was assigned to 734 records, of which 356 and 306 records were assigned to the subspecies fastidiosa and pauca, respectively. One record was identified as belonging to the species X. taiwanensis instead of X. fastidiosa subsp. unknown. In 58 records, it was also possible to assign the Sequence type (ST) to the strain, thanks to personal communications of the authors of the publications.
Following the new rationale for reporting geographic coordinates (see Section 2.4), coordinates were included only when specified in the related publications. Such coordinates may refer to single plants, fields or administrative divisions at different level (town, province, regions etc.) and with different level of precision. For more information on the reported geographical coordinates, the related publication was the only source of information that was consulted for this database.
Host plant species of Xylella spp.The updated total numbers of plant species, genera and families host of Xylella spp., according to the classification system described in Section 2.5.2, are reported in Table . The numbers vary from 343 host plant species, 163 genera and 64 families according to category A (i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture) or positive with one method (between: sequencing, culture)) to 595 plant species, 275 genera and 85 families of category E (i.e. all positives plant species reported, regardless of the detection methods). Due to the update of some data already present in the first version of the database (EFSA, ), some host plants already present in the database were reclassified in a different category.
Number of host plant species, genera and families of Xylella spp. according to categories A, B, C, D, E (based on the detection methods applied – see Section 2.5.2)
| A | B | C | D | E | |
| Number of host plant species | 343 | 348 | 578 | 587 | 595 |
| Number of host genera | 163 | 164 | 274 | 274 | 275 |
| Number of host families | 64 | 64 | 85 | 85 | 85 |
Compared to the database published in 2018 (EFSA, ), 37 new host plant species have been identified for X. fastidiosa. Three plant species have been removed from the list of host plants: data on Citrus volkameriana (reported infected by X. fastidiosa in unspecified conditions) were erroneously interpreted, data on Prunus × amygdalo-persica artificially infected by X. fastidiosa subsp. pauca strain CoDiRO were updated, while the plant species Quercus pubescens has been now considered as unconfirmed (see Section 3.1.2). Details on those 37 new host plants are reported in Table . No new host plant species have been identified for the species X. taiwanensis.
Thirty new plant species have been identified as host plants of X. fastidiosa according to category A, and seven according to category C (as described in Section 2.5.2). Most of the new host plant species were naturally infected and identified both in the EU (France, Italy, Portugal and Spain) and outside the EU (Iran and the United States of America). Pistacia vera was also tested in experimental conditions and three plant taxa (Hibiscus fragilis, Hibiscus sp., Vaccinium darrowii) were reported infected in not specified conditions. The X. fastidiosa subspecies identified in the new host plants were multiplex, pauca or not reported (unknown).

The overall number of host plant species infected naturally, artificially and in unspecified conditions by the different X. fastidiosa subspecies and according to the different categories are reported in Tables , and , whereas the pathogen species Xylella taiwanensis was recorded only in the plant species Pyrus pyrifolia.
Considering the plant species naturally infected, the highest number of host plants is recorded for the subspecies multiplex (141 plant species for cat. A) and for unknown X. fastidiosa subspecies (152 plant species for cat. A, increasing to 371 for cat. E). The highest number of plant species artificially infected by X. fastidiosa is recorded for unknown subspecies (89 plant species for cat. A, rising to 2015 for cat. E) and for the subspecies fastidiosa (37 for cat. A).

The plant species behind the numbers shown in Tables , and are listed in Appendices A, B and C. In those appendices, the full lists of plant species infected by the different X. fastidiosa subspecies naturally, artificially and in not specified conditions according to the five categories are shown.
The ‘top 10’ host plant families, i.e. the families owning the highest numbers of host plant species, are shown in Figure . Fabaceae appears to be the plant family owning the highest number of host plants (61), followed by Asteraceae (57) and Vitaceae (48).
Enlarge this image.This figure shows the top 10 host plant families for Xylella spp. and the number of host plant species within each family
Infection by Xylella spp. can be detected using different detection techniques, sometimes providing non-convergent results (i.e. the sample is positive to one or more detection methods but negative for others). Records reporting non-convergent results are reported in the database but have not been included in the data analysis.
X. fastidiosa Sequence Types and host plants associationThe full list of plant species infected by the different X. fastidiosa Sequence Types (ST) in natural, artificial and not specified conditions is reported in Appendix D. For each plant species, the number of records reporting infection by that specific ST is counted. For natural infection, it is also reported the country where the plant species have been identified, whereas for artificial and not specified infection only, the total number of records is present in the Appendix.
Totally, 1,202 records reporting information on 194 plant species infected by 87 different STs have been reported in the database. Most of the records (884) refer to natural infections that were reported in North, Central and South America (United States of America, Mexico, Honduras, Costa Rica, Ecuador, Brazil and Argentina) and Europe (Portugal, Spain, France and Italy). The highest number of records for artificial infections belong to STs of subsp. pauca (127 records), whereas ST1 (subsp. fastidiosa) is the most studied ST with 95 records.
Compared to the previous version of the database (EFSA, ), six new STs have been identified worldwide. In the United States of America, Vaccinium ashei has been reported as infected by STs 82 and 83 (subsp. multiplex), and in Brazil STs 84, 85 and 86 (subsp. pauca) have been identified in Olea europaea plants. In Italy, ST 87 belonging to subsp. multiplex has been detected in several plant species in Monte Argentario (Tuscany).
Tolerant and resistant response of plant speciesInformation on tolerant and resistant response of plant species to X. fastidiosa infection have been also reported in the database. The list of plant genera and species for which tolerant and resistant response have been identified is reported in Table . Information on tolerant/resistant status have been reported in 64 plant species with a total number of 491 records, but the most studied genera are Vitis, Citrus and Prunus (224, 175 and 54 records, respectively), reflecting the important economic value of their plant species.

Eleven categories have been created to group different tolerant/resistant response to X. fastidiosa infection. Those categories include the plant response/s for which the authors of the publication considered that plant as tolerant/resistant to X. fastidiosa infection. One hundred and eight publications, recorded in 491 record (245 for artificial infections), report information on tolerance and resistance outcome to X. fastidiosa infection (Table ). In 41 publications, the authors consider the plant tolerant or resistant, but without adding further details, whereas in 19 publications, the lower bacterial populations harboured by the plant was considered the demonstration of the tolerant/resistant status of the plant. With more than 70 records, the lack of infection and lack or reduction of symptoms (in both natural and artificial infections) are the two most reported tolerant/resistant outcome.
Number of records and publications for tolerance/resistance category
Following a request of the European Commission, EFSA was asked in 2016 to create, maintain and regularly update a database of host plant species of Xylella spp. In 2018, EFSA released a new and renovated Xylella spp. host plant database (EFSA, ), that was now updated.
An extensive literature search was performed including all scientific papers published up to 30 June 2019, as well as additional documents obtained from research groups, personal communications of experts, EFSA Horizon Scanning activities for Plant Health and Europhyt outbreak notifications (last accessed on 15 October 2019). By these searches, 271 recent publications were collected and screened to select the publications in which Xylella spp. was studied in association with a plant species. As a result, 76 publications were selected and informative data on botanical identification of the plant species, infection method, geographical information, Xylella spp. genetics, detection techniques and tolerant/resistant response of the plant were extracted.
Some data already included in the database published in 2018 were updated: in particular, the X. fastidiosa subspecies was identified for several strains, thanks to references review and author's personal communications; in this update, only geographical coordinates explicitly reported in the publications were reported.
Thirty-seven new host plant species of X. fastidiosa were added to the database. Most of those plant species were naturally infected and identified in France, Iran, Italy, Portugal, Spain and the United States of America. X. fastidiosa subspecies infecting the new host plants were multiplex, pauca or not identified (unknown/not reported in the study). No new data were retrieved for X. taiwanensis that up to now has been reported only in Pyrus pyrifolia plants.
The overall number of Xylella spp. host plants reached 343 plant species, 163 genera and 64 families for category A (i.e. plant species positive with at least two detection methods (among: symptoms observation on the test plant in experimental vector transmission, ELISA, other immunological techniques, PCR-based methods, sequencing and culture) or positive with one method (between: sequencing, culture), till 595 plant species, 275 genera and 85 families for category E (i.e. all positives plant species reported, regardless of the detection methods).
Since the release of the first version of this database (EFSA, ), six new Multilocus Sequence Types (STs) have been identified worldwide: STs 82 and 83 (subsp. multiplex) in the United States of America, STs 84, 85 and 96 (subsp. pauca) in Brazil and ST 87 (subsp. multiplex) in Italy.
Information on tolerant/resistant status were reported for 64 plant species in 108 publications, with a total number of 491 records. The economically important Vitis, Citrus and Prunus genera are the most studied and reported plant taxa.
The EFSA database on Xylella spp. host plants will be updated regularly and it aims to provide useful information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp.
