Mechanisms and Challenges in the Application of Arbuscular Mycorrhizal Fungi in Enhancing Drought Tolerance in Fruit Trees
摘要
Abstract
In light of global climate change,drought stress has emerged as a significant abiotic factor limiting the development of the fruit production industry.Arbuscular mycorrhizal fungi(AMF),which form mutualistic symbiotic associations with the roots of most plants(including the vast majority of fruit trees),play a crucial role in enhancing drought tolerance in plants.This review highlights the effects of drought on AMF colonization within fruit tree roots and summarizes the potential mechanisms through which AMF enhance drought tolerance.These mechanisms encompass the enhanced water uptake and transport,the facilitation of nutrient acquisition,the modulation of osmotic adjustment,the activation of antioxidant defense mechanisms,the maintenance of photosynthesis and growth,the regulation of polyamine homeostasis,the optimization of fatty acid metabolism,and the acceleration of signal transduction pathways.Furthermore,this review discusses the existing applications,prospects,and challenges associated with using AMF in the fruit tree cultivation for drought resistance.Additionally,future researches are proposed to lay the groundwork for utilizing AMF technology to mitigate drought stress and achieve water-efficient,high-yield fruit tree cultivation.关键词
