Abstract: Plant growth and development are affected by various environmental factors. In response to various environmental changes, plants have evolved a series of signal recognition and transduction proteins, such as the plasma membrane-localized receptor-like kinases (RLKs), to cope with the environmental conditions. The lectin receptor-like kinases (LecRLKs) are a subfamily of RLKs that contain three structural domains: the extracellular lectin domain, transmembrane domain, and the intracellular kinase domain. Based on the structural difference of the extracellular lectin domain, LecRLKs are classified into three subclasses: L-, G-, and C-type. Recent studies have shown that LecRLKs play a vital role in plant development and biotic/abiotic stress responses. In this review, we discribe the research history, structural features and classification, and biological functions of LecRLKs, and emphasize on the functions of LecRLKs in plants in response to biotic/abiotic stresses and in regulating development. This review provides a view for future functional study on LecRLKs and crop improvement by elaborating different types and functions of LecRLKs.

Key words: receptor-like kinase, lectin receptor-like kinase, biotic/abiotic stress, plant growth and development
