Endophytic Fungi: Biological Control and Induced Resistance to Phytopathogens and Abiotic Stresses

Abstract

Plant diseases cause losses of approximately 16% globally. Thus, management measures must be implemented to mitigate losses and guarantee food production. In addition to traditional management measures, resistance induction and biological control have gained ground in agriculture due to their enormous potential. Endophytic fungi colonize plant tissues internally and have the potential to act as biological control agents, as elicitors in the process of resistance induction and in attenuating abiotic stresses. In this review, we list the action of this group of microorganisms as potential agents which can act in controlling plant diseases and describe several examples in which endophytes were able to reduce the damage caused by pathogens and adverse conditions. This is due to their arsenal of molecules generated during the interaction by which they form a kind of biological shield in the plant. Studies on these microorganisms have grown due to the existing diversity and the multiple benefits they can offer. Finally, considering that endophytic fungi can be an important tool in managing diseases due to the large amount of biologically active substances produced, bioprospecting this class of microorganisms is tending to increase and generate valuable products.

The use of biological agents in controlling diseases of shallots for tss production

“…Biological control using microorganisms has been proven successful in controlling various plant diseases in many countries [10][11][12]. The plant resistance induction method is a method that has the potential to reduce the severity of a plant pathogen disease and can increase the level of resistance to subsequent attacks [13,14]. The inducer can be useful beneficial microorganisms or certain chemicals such as salicylic acid and asibenzolar-s-methyl-mankozeb which induce systemic resistance (SAR) in plants [15].…”
