BRI113

BRI113 is a gene identified in various plant species, most notably *Arabidopsis thaliana*. It encodes a protein that plays a role in plant growth and development. Specifically, BRI113 is a member of the BRI1-associated kinase (BAK) family. These kinases are known to be involved in the brassinosteroid signaling pathway, a crucial system for regulating plant cell elongation, division, and differentiation.

The brassinosteroid pathway is initiated by the perception of brassinosteroid hormones by the receptor kinase BRI1. BRI113, along with other BAK proteins, acts downstream of BRI1, mediating the signal transduction that ultimately affects gene expression. While the precise functions of individual BAK proteins can be complex and sometimes redundant, research suggests that BRI113 contributes to the fine-tuning of brassinosteroid responses. Studies involving mutations in BRI113 have indicated its involvement in processes such as root development and flowering time in *Arabidopsis*. Understanding the specific contributions of BRI113 helps to elucidate the intricate mechanisms governing plant hormone signaling and its impact on overall plant architecture and fitness. Further research continues to explore its precise molecular interactions and physiological roles.
