Convergent Evolution of Filamentous Microbes Towards Evasion of Glycan-Triggered Immunity

Hanna Rovenich et al. New Phytol.

Abstract

896 I. 896 II. 896 III. 897 IV. 898 V. 899 VI. 899 900 References 900 SUMMARY: All filamentous microbes produce and release a wide range of glycans, which are essential determinants of microbe-microbe and microbe-host interactions. Major cell wall constituents, such as chitin and β-glucans, are elicitors of host immune responses. The widespread capacity for glycan perception in plants has driven the evolution of various strategies that help filamentous microbes to evade detection. Common strategies include structural and chemical modifications of cell wall components as well as the secretion of effector proteins that suppress chitin- and β-glucan-triggered immune responses. Thus, the necessity to avoid glycan-triggered immunity represents a driving force in the convergent evolution of filamentous microbes towards its suppression.

Keywords: chitin; effector; glycan recognition; microbial cell wall; β-glucan.
