Endophytic Fungi for Crops Adaptation to Abiotic Stresses

Area of Science:

• Agricultural Science
• Mycology
• Plant Science

Background:

• Abiotic stresses (drought, salinity, extreme temperatures) significantly reduce crop productivity globally.
• Endophytic fungi (EFs) are microorganisms residing within plant tissues, offering potential benefits to hosts.
• EFs are increasingly recognized for their role in modulating plant responses to environmental challenges.

Purpose of the Study:

• To review and synthesize current knowledge on the role of endophytic fungi in enhancing crop adaptation to abiotic stress.
• To explore the mechanisms by which EFs confer stress tolerance to plants.
• To highlight advancements and future directions in the application of EFs in agriculture.

Main Methods:

• Literature review synthesizing existing research on endophytic fungi and crop stress tolerance.
• Analysis of mechanisms employed by EFs, including osmolyte synthesis, enzyme production, and hormonal modulation.
• Examination of molecular techniques for identifying and characterizing stress-tolerant EF strains.

Main Results:

• EFs effectively alleviate adverse effects of abiotic stresses through various physiological and biochemical mechanisms.
• EFs promote nutrient uptake and modulate plant hormone balance, enhancing overall stress tolerance.
• Identification and characterization of stress-tolerant EF strains are advancing their potential agricultural applications.

Conclusions:

• EFs represent a promising avenue for improving crop resilience to abiotic stresses, contributing to sustainable agriculture.
• The symbiotic relationship with EFs offers ecological benefits, including improved soil health and reduced chemical input reliance.
• Further research is needed to fully understand EF-plant interactions and optimize their application in diverse agricultural systems.
