“…Lignin accumulation may thus be seen as an alternative strategy employed by plants for cell wall reinforcement in the absence of cellulose synthesis. Interestingly, the malectin-like sites in the extracellular domain of this protein family are thought to mediate interactions with cell wall polysaccharides (Lindner et al, 2012). Although a small peptide was recently found to be the ligand of the FER extracellular domain (Haruta et al, 2014), cell wall polysaccharides could nonetheless represent alternative ligands, consistent with the implication of other CrRLK1-like proteins in cell wall integrity sensing.…”

“…Nath et al, 2003). FER has also been implicated in male-female interactions during pollen tube reception, in root hair development, and in the response to pathogen attacks (Lindner et al, 2012). In addition, FER was shown to influence various hormonal pathways such as the auxin, brassinosteroid, ethylene and abscisic acid signalling pathways (Lindner et al, 2012), suggesting that it plays a role in integrating mechanical stress signals with other chemical/hormonal signalling pathways required for the control of plant growth and development.…”

Developing a ‘thick skin’: a paradoxical role for mechanical tension in maintaining epidermal integrity?

Plant aerial epidermal tissues, like animal epithelia, act as loadbearing layers and hence play pivotal roles in development. The presence of tension in the epidermis has morphogenetic implications for organ shapes but it also constantly threatens the integrity of this tissue. Here, we explore the multi-scale relationship between tension and cell adhesion in the plant epidermis, and we examine how tensile stress perception may act as a regulatory input to preserve epidermal tissue integrity and thus normal morphogenesis. From this, we identify parallels between plant epidermal and animal epithelial tissues and highlight a list of unexplored questions for future research.

“…Indeed, FER plays roles in seedling development, root hair growth, trichome morphogenesis, responses to hormone and pathogen. The function of FER and CrRLK1L family has been discussed by several excellent reviews (Boisson-Dernier et al, 2011;Cheung and Wu, 2011;Lindner et al, 2012). Here we will mainly focus on its role in pollen tube reception.…”

“…RbohD is activated via the direct phosphorylation by cytosolic kinase in the RLK complex during pathogen response (Li et al, 2014), it would be plausible to speculate that MRI or other cytosolic kinases also activate RbohH/J. It was proposed that ANX and the CrRLK1L family, as a signaling integrator, could sense the cell wall integrity simultaneously (Cheung and Wu, 2011;Lindner et al, 2012). The CrRLK1L family contains two malectin-like domains at the extracellular region sharing limited homology with the animal endoplasmic reticulum-localized malectin that bind di-glucose (Schallus et al, 2008).…”

Different from animals, sessile plants are equipped with a large receptor-like kinase (RLK) superfamily. RLKs are a family of single trans-membrane proteins with divergent N-terminal extracellular domains capped by a signal peptide and C-terminal intracellular kinase. Researches in the last two decades have uncovered an increasing number of RLKs that regulate plant development, stress response and sexual reproduction, highlighting a dominant role of RLK signaling in cell-to-cell communications. Sexual reproduction in flowering plants is featured by interactions between the male gametophyte and the female tissues to facilitate sperm delivery and fertilization. Emerging evidences suggest that RLKs regulate almost every aspect of plant reproductive process, especially during pollination. Therefore, in this review we will focus mainly on the function and signaling of RLKs in plant male-female interaction and discuss the future prospects on these topics.
