Abstract

Plants survey their environment for the presence of potentially harmful or beneficial microbes. During colonization, cell surface receptors perceive microbe-derived or modified-self ligands and initiate appropriate responses. The recognition of fungal chitin oligomers and the subsequent activation of plant immunity are well described. In contrast, the mechanisms underlying beta-glucan recognition and signaling activation remain largely unexplored. Here, we systematically tested immune responses towards different beta-glucan structures and show that responses vary between plant species. While leaves of the monocots Hordeum vulgare and Brachypodium distachyon can recognize longer (laminarin) and shorter (laminarihexaose) beta-1,3-glucans with responses of varying intensity, duration and timing, leaves of the dicot Nicotiana benthamiana activate immunity in response to long beta-1,3-glucans, whereas Arabidopsis thaliana and Capsella rubella perceive short beta-1,3-glucans. Hydrolysis of the beta-1,6 side-branches of laminarin demonstrated that not the glycosidic decoration but rather the degree of polymerization plays a pivotal role in the recognition of long-chain beta-glucans. Moreover, in contrast to the recognition of short beta-1,3-glucans in A. thaliana, perception of long beta-1,3-glucans in N. benthamiana and rice is independent of CERK1, indicating that beta-glucan recognition may be mediated by multiple beta-glucan receptor systems.
