Scientists review research on CrRLK1L receptor kinase signaling network |
Recently, the team of Professor Yu Feng of Hunan University published an online review article in "New Botanist", summarizing decades of findings on the CrRLK1L receptor kinase signaling network, and looking forward to future research directions
.
Receptor-like kinases (RLKs) are the largest receptor family in plants and are important molecules for plants to perceive and transmit various environmental stimuli
.
The Arabidopsis genome encodes more than 600 receptor-like kinase (RLK) genes, which mediate the inside and outside of plant cell membranes by recognizing different ligands including their own hormone signals, small peptide signals, and foreign pathogen-related molecular patterns (PAMP).
In the past few decades, researchers have made great progress in elucidating the mechanism of action of several RLKs, and emerging paradigms have pointed out their role in cellular adaptation
.
Among these research paradigms, CrRLK1L protein kinase family proteins and their RALF peptide ligands have attracted widespread attention
FERONIA (FER) is a CrRLK1L protein that participates in a wide range of physiological processes related to RALF signaling.
It is a central regulator of stress response, plant hormone response, energy/RNA metabolism and transcription
.
In this article, the author analyzed the status of CrRLK1L members and their ligands in various species
.
Summarizes the working model of FER, and raises many questions about the role of CrRLK1L signal network in the process of cell adaptation
