摘要
生物体是高度相互联系的相互作用网络的一部分,其特征是物种培育,竞争,寄生和相互捕食。植物已经发展了合作以及防御策略来与邻居生物体进行交互。其中,植物 - 真菌协会是非常多样的,从致病到互惠。我们目前的植物 - 真菌相互作用的知识表明一个复杂的协同进化,以确保动态植物对不断发展的真菌互助/致病策略的反应。 植物 - 真菌通讯依赖丰富的化学语言。为了操纵植物防御机制,真菌产生和分泌几种类型的生物分子,其作用模式很大程度上是未知的。感知真菌后,植物会产生植物激素和一系列次级代谢产物,作为防御入侵者的机制或促进互惠关系。这些相互作用的化学信号可以被致病性真菌选择用于其自身利益。 在调节植物 - 真菌相互作用的植物分子中,植物激素在调节植物发育,防御和应激反应的各个方面发挥关键作用。有趣的是,真菌也可以产生植物激素,尽管真菌产生的植物激素在植物 - 真菌相互作用中的实际作用知之甚少。在这里,我们讨论植物激素的真菌生产的最新进展,它们作为内源性真菌信号的假定作用,以及真菌怎样操纵植物激素平衡对其好处。

摘要: Living organisms are part of a highly interconnected web of interactions, characterised by species nurturing, competing, parasitizing and preying on one another. Plants have evolved cooperative as well as defensive strategies to interact with neighbour organisms. Among these, the plant-fungus associations are very diverse, ranging from pathogenic to mutualistic. Our current knowledge of plant-fungus interactions suggests a sophisticated coevolution to ensure dynamic plant responses to evolving fungal mutualistic/pathogenic strategies.
The plant-fungus communication relies on a rich chemical language. To manipulate the plant defence mechanisms, fungi produce and secrete several classes of biomolecules, whose modeof- action is largely unknown. Upon perception of the fungi, plants produce phytohormones and a battery of secondary metabolites that serve as defence mechanism against invaders or to promote mutualistic associations. These mutualistic chemical signals can be co-opted by pathogenic fungi for their own benefit.
Among the plant molecules regulating plant-fungus interaction, phytohormones play a critical role since they modulate various aspects of plant development, defences and stress responses. Intriguingly, fungi can also produce phytohormones, although the actual role of fungalproduced phytohormones in plant-fungus interactions is poorly understood. Here, we discuss the recent advances in fungal production of phytohormone, their putative role as endogenous fungal signals and how fungi manipulate plant hormone balance to their benefits.
