Abstract

Plant cell walls are essential elements for disease resistance that pathogens need to overcome to colonise the host. Certain pathogens secrete a large battery of enzymes to hydrolyse plant cell wall polysaccharides, which leads to the release of carbohydrate-based molecules (glycans) that are perceived by plant pattern recognition receptors and activate pattern-triggered immunity and disease resistance. These released glycans are used by colonizing microorganisms as carbon source, chemoattractants to locate entry points at plant surface, and as signals triggering gene expression reprogramming. The release of wall glycans and their perception by plants and microorganisms determines plant-microbial interaction outcome. Here, we summarise and discuss the most recent advances in these less explored aspects of plant-microbe interaction.

植物细胞壁:植物与病原体相互作用中基于碳水化合物的信号源
植物细胞壁是抗病的基本要素,病原体需要克服这些要素才能在宿主体内定居。某些病原体会分泌大量酶来水解植物细胞壁多糖,从而释放出以碳水化合物为基础的分子(聚糖),这些分子会被植物模式识别受体感知,并激活模式触发免疫和抗病能力。定殖微生物利用这些释放的聚糖作为碳源和趋化吸引剂,以确定植物表面的进入点,并作为触发基因表达重编程的信号。植物和微生物对壁糖的释放和感知决定了植物与微生物相互作用的结果。在此,我们总结并讨论了植物与微生物相互作用中这些探索较少的方面的最新进展。
