摘要:

多角度深入探究果园中丛枝菌根(arbuscular mycorrhiza,AM)真菌的多样性及其与果树的互作机制,对于克服果树生产中生物和非生物胁迫的限制、推动果园可持续发展具有重要意义。本文中系统综述了果园土壤生态系统中AM真菌的物种多样性、影响AM真菌多样性与群落构建的关键驱动因素,以及AM真菌增强果树对水分与矿质元素的吸收和激活宿主系统性抗逆信号通路等方式提高果树抗性的生理生化及分子机制,并对AM真菌在果树绿色生产中的潜在应用前景与未来研究方向进行展望。

Abstract:

A comprehensive investigation into the diversity of arbuscular mycorrhizal(AM)fungi in orchards and their mechanisms of interaction with fruit trees is of great significance for overcoming the limitations posed by biotic and abiotic stresses in fruit production and promoting the sustainable development of orchards. This paper systematically reviews AM fungal species diversity in orchard soil ecosystems,the key driving factors influencing their diversity and community assembly,and the physiological,biochemical,and molecular mechanisms underlying AM fungal enhancement of fruit tree resistance. These mechanisms include enhancing the uptake of water and mineral nutrients and activating the host's systemic resistance signaling pathways. Finally,the potential applications of AM fungi in sustainable orchard management and future research directions are discussed.
