Advances in Research on Plant Lectin Receptor-like Kinases

Abstract:

Plant lectin receptor-like kinases (LecRLKs), which belong to the family of plant receptor-like kinases, are a group of plant membrane protein receptors. LecRLKs are primarily composed of extracellular lectin domains, transmembrane domains, and intracellular kinase domains. They can be classified into G-type, L-type, and C-type based on the specificity of their extracellular domains. In plants, lectin receptor-like kinases play a significant role in regulating growth, development, and environmental responses. This article provides a comprehensive review of the research history, structure, and classification of lectin receptor-like kinases, systematical elucidation of their critical functions in plant growth, development, and responses to environmental stimuli, and categorization of genes with established functions. The article also discusses the limitations in previous lectin receptor-like kinase researches, including the lack of evolutionary history elucidation, unclear signal pathways, and unidentified ligands. Based on the current state of researches, the specific recommendations are proposed with the aim of providing theoretical support for targeted breeding within the gene family.
