Exploring extremophilic fungi in soil mycobiome for sustainable agriculture amid global change

Abstract

As the Earth warms, alternatives to traditional farming are crucial. Exploring fungi, especially poly extremophilic and extremotolerant species, to be used as plant probiotics, represents a promising option. Extremophilic fungi offer avenues for developing and producing innovative biofertilizers, effective biocontrol agents against plant pathogens, and resilient enzymes active under extreme conditions, all of which are crucial to enhance agricultural efficiency and sustainability through improved soil fertility and decreased reliance on agrochemicals. Yet, extremophilic fungi’s potential remains underexplored and, therefore, comprehensive research is needed to understand their roles as tools to foster sustainable agriculture practices amid climate change. Efforts should concentrate on unraveling the complex dynamics of plant-fungi interactions and harnessing extremophilic fungi’s ecological functions to influence plant growth and development. Aspects such as plant’s epigenome remodeling, fungal extracellular vesicle production, secondary metabolism regulation, and impact on native soil microbiota are among many deserving to be explored in depth. Caution is advised, however, as extremophilic and extremotolerant fungi can act as both mitigators of crop diseases and as opportunistic pathogens, underscoring the necessity for balanced research to optimize benefits while mitigating risks in agricultural settings.

Understanding fungal-plant interactions is vital to foster sustainable agriculture practices amidst climate change. Extremophilic fungi’s potential as plant probiotics can be crucial to increase crop yields while reducing dependence on toxic agrochemicals. However, the benefits and risks of extremophilic fungi used to promote plant growth and development should be carefully considered.
