BRI1like

BRI1like refers to a family of plant receptor-like kinases (RLKs) that are structurally and functionally related to BRI1 (Brassinosteroid Insensitive 1). BRI1 is the primary receptor for brassinosteroid (BR) hormones, which play crucial roles in plant growth and development, including cell expansion, division, and differentiation. BRI1like proteins share conserved domains with BRI1, such as an extracellular leucine-rich repeat (LRR) domain and an intracellular kinase domain.

While BRI1 is the canonical BR receptor, BRI1like proteins have emerged as important regulators of plant development, often exhibiting overlapping or distinct functions. Some BRI1like genes have been shown to be involved in BR signaling pathways, either by acting as co-receptors with BRI1, mediating downstream signaling events, or by regulating the expression of BR-responsive genes. Others may have evolved to perceive different ligands or to participate in signaling pathways independent of brassinosteroids.

The study of BRI1like genes provides insights into the complexity and redundancy of plant hormone signaling networks. Different BRI1like proteins can contribute to fine-tuning developmental processes and responding to environmental cues. Understanding the specific roles of each BRI1like member is an ongoing area of research in plant biology, contributing to our knowledge of how plants regulate their growth and development.
