The apoplast is a continuous compartment in plants that connects cells between tissues and organs, serving as an important site for interaction between plants and microbes. The plant cell wall, occupying most of the apoplast, consists of polysaccharides, proteins, and ions. It acts as a physical barrier and nutrient source for the microbe, while also playing crucial roles in interkingdom detection, recognition, and response to other organisms. Both plant and microbe modify the cell wall and its environment to benefit from the interaction, and understanding these dynamic changes is essential for comprehending plant-microbe interactions.
The apoplast is a continuous plant compartment that connects cells between tissues and organs and is one of the first sites of interaction between plants and microbes. The plant cell wall occupies most of the apoplast and is composed of polysaccharides and associated proteins and ions. This dynamic part of the cell constitutes an essential physical barrier and a source of nutrients for the microbe. At the same time, the plant cell wall serves important functions in the interkingdom detection, recognition, and response to other organisms. Thus, both plant and microbe modify the plant cell wall and its environment in versatile ways to benefit from the interaction. We discuss here crucial processes occurring at the plant cell wall during the contact and communication between microbe and plant. Finally, we argue that these local and dynamic changes need to be considered to fully understand plant-microbe interactions. Plants and microbes modify the host cell wall to benefit from the interaction by altering its properties, which are defined by the biochemistry of its polysaccharides, regulated by cell wall ions and proteins.
