Abstract

The interaction between plants and fungal pathogens comprises a range of mechanisms that determine the outcome of the interaction, i.e., compatible leading to susceptibility or incompatible leading to resistance. Several host defense mechanisms act both in susceptible and resistant plants. Yet, in the case of a compatible interaction involving a susceptible host and a virulent pathogen, the latter is able to win the battle and cause disease. By documenting several interactions between plant and fungal pathogens, this review describes some of the mechanisms which plants use for defense such as the reinforcement of the cell wall and the accumulation of pathogenesis-related (PR) proteins and of secondary metabolites and ways by which pathogens overcome plant defense.

真菌发病过程中的宿主防御机制及其如何在易感植物中被克服:综述

植物与真菌病原体之间的相互作用包括一系列决定相互作用结果的机制，即相容导致易感性或不相容导致抗性。几种寄主防御机制在易感和抗性植物中都起作用。然而，在涉及易感宿主和毒性病原体的相容相互作用的情况下，后者能够赢得战斗并引起疾病。本文综述了植物与真菌病原体之间的几种相互作用，阐述了植物用于防御的一些机制，如细胞壁的强化、致病相关蛋白(PR)和次生代谢物的积累以及病原体克服植物防御的途径。

期刊介绍： Phyton-International Journal of Experimental Botany is an international journal that publishes on the broadest aspects of plant biology and ecology. The journal welcomes the original and exciting submissions that provide new and fundamental insights into the origins, development, and function of plants from the molecular to the whole organism and its interactions within the biotic and abiotic environment. Phyton-International Journal of Experimental Botany publishes outstanding research in the plant and ecology sciences, especially in the areas of plant physiology and biochemistry, plant metabolism, plant ecology and evolution, as well as those making use of synthetic, modeling, bioinformatics, and -omics tools. Manuscripts submitted to this journal must not be under simultaneous consideration or have been published elsewhere, either in part or in whole.
