细胞壁是一种复杂的结构，主要由嵌入粘性果胶基质中的纤维素-半纤维素网络组成。果胶以高度甲基酯化的形式合成，并在 muro 中通过果胶甲基酯酶 (PME) 进行脱酯化。甲酯化的程度和模式影响细胞壁的结构和特性，从而影响植物的生理过程及其对病原体的抵抗力。 PME 活性使果胶更容易受到病原体产生的酶的作用，从而在植物与病原体相互作用的结果中发挥着至关重要的作用。本综述重点关注果胶甲酯化在植物-病原体相互作用中的影响以及其在发病过程中改变的动态作用。 (c) 2012 年爱思唯尔有限公司。版权所有。
The cell wall is a complex structure mainly composed by a cellulose-hemicellulose network embedded in a cohesive pectin matrix. Pectin is synthesized in a highly methyl esterified form and is de-esterified in muro by pectin methyl esterases (PMEs). The degree and pattern of methyl esterification affect the cell wall structure and properties with consequences on both the physiological processes of the plants and their resistance to pathogens. PME activity displays a crucial role in the outcome of the plant-pathogen interactions by making pectin more susceptible to the action of the enzymes produced by the pathogens. This review focuses on the impact of pectin methyl esterification in plant-pathogen interactions and on the dynamic role of its alteration during pathogenesis. (c) 2012 Elsevier GmbH.
