Abstract:

The leucinerich repeats receptorlike protein kinase (LRRRLK) belongs to the transmembrane receptorlike kinase in plant, and it is made up by 3 parts containing leucinerich repeats (LRRs) domain, a transmembrane (TM) domain, and a functional protein kinase domain. As signal recognition receptor, the LRRRLK participates in the signal transduction process of CLV, BR and Ax21 in different plants, and plays important roles in plant development and cell growth, hormone signaling and stress responses. In this review, we described the research progress on regulatory function and molecular mechanism of LRRRLK in recent years, and provided a reference for further exploring the function and application of LRRRLK.
