“…FER is the most extensively studied member of the malectin domain-containing receptor-like kinase (MLD-RLK) (also known as Catharanthus roseus RLK1-LIKE or CrRLK1L) family. It plays broad and profound roles in diverse processes including sexual reproduction, development of root hair, hormonal responses, mechanic sensing, plant-microbe interactions, and maintaining CWI under abiotic stresses (15)(16)(17)(18)(19)(20)(21)(22)(23)(24). Previous studies have shown that BR increases FER RNA level (12).…”

Plant cell expansion is driven by turgor pressure and regulated by hormones. How plant cells avoid cell wall rupture during hormone-induced cell expansion remains a mystery. Here we show that brassinosteroid (BR), while stimulating cell elongation, promotes the plasma membrane (PM) accumulation of the receptor kinase FERONIA (FER), which monitors cell wall damage and in turn attenuates BR-induced cell elongation to prevent cell rupture. The GSK3-like kinase BIN2 phosphorylates FER, resulting in reduced FER accumulation and translocation from endoplasmic reticulum to PM. By inactivating BIN2, BR signaling promotes dephosphorylation and increases PM accumulation of FER, thereby enhancing the surveillance of cell wall integrity. Our study reveals a vital signaling circuit that coordinates hormone signaling with mechanical sensing to prevent cell bursting during hormone-induced cell expansion.One-Sentence SummaryBrassinosteroid recruits a cell wall integrity monitor to prevent growth-induced cell wall damage.

“…Our findings highlight the importance of the putative IDR in the extended C terminus of P2K1 in regulating eATP signaling, especially in the eATP-induced regulation of primary root growth. Additionally, our results suggest a critical role for eATP and P2K1 in regulating ROS and cell wall integrity in the primary root meristem, which are essential for plant growth and stress adaptation [57][58][59][60][61][62][63]. This study also provides a framework for generating other truncated RK variants based on IDRs that can help further unravel the functional significance of the C terminus in other receptor proteins.…”

The intrinsically disordered C‐terminus of purinoceptor P2K1 fine‐tunes plant responses to extracellular ATP

P2K1 is a plant‐specific purinoceptor that perceives extracellular ATP (eATP), a signaling molecular implicated in various physiological processes. Interestingly, P2K1 harbors a C‐terminal intrinsically disordered region (IDR). When we overexpressed a truncated P2K1 (P2K1t) lacking the IDR, primary root growth completely ceased in response to eATP. We investigated the functional roles of the IDR in P2K1 using a combination of molecular genetics, calcium imaging, gene expression analysis, and histochemical approaches. We found that the P2K1t variant gave rise to an amplified response to eATP, through accumulation of superoxide, altered cell wall integrity, and ultimate cell death in the primary root tip. Together, these observations underscore the significant involvement of the C‐terminal tail of P2K1 in root growth regulation.

“…Pectin is likely to be involved in cell wall loosening and remodeling, and PG, PL, and PE are plant hydrolytic enzymes that modulate the firmness or softening of cell walls through pectin disassembly (Atmodjo et al, 2013;Khan et al, 2019). The cell wall remodeling and the release of elicitor-active pectic polysaccharides are affected by FER receptor-like kinase (Liu et al, 2023). Duan et al (2020) demonstrated that FER is crucial for maintenance of de-esterified pectin.…”

Cold is one of the main abiotic stresses in temperate fruit crops, affecting the yield and fruit quality of apple in China and European countries. The plant receptor-like kinase FERONIA is widely reported to be involved in abiotic stresses. However, its function in apple cold resistance remains unknown. Modification of cell wall components and accumulation of soluble sugars and amino acids are important strategies by which plants cope with cold. In this study, expression of the apple FERONIA receptor-like kinase gene MdMRLK2 was rapidly induced by cold. Apple plants overexpressing MdMRLK2 (35S:MdMRLK2) showed enhanced cold resistance relative to the wild type. Under cold conditions, 35S:MdMRLK2 apple plants had higher amounts of water insoluble pectin, lignin, cellulose, and hemicellulose, which may have resulted from reduced activities of polygalacturonase, pectinate lyase, pectinesterase, and cellulase. More soluble sugars and free amino acids and less photosystem damage were also observed in 35S:MdMRLK2 apple plants. Intriguingly, MdMRLK2 interacted with the transcription factor MdMYBPA1 and promoted its binding to MdANS and MdUFGT promoters, leading to more anthocyanin biosynthesis, particularly under cold conditions. These findings complemented the function of apple FERONIA MdMRLK2 responding to cold resistance.
