Summary:

Research in our laboratory focuses on the developmental genetics of plant reproduction, with an emphasis on cell-cell communication and epigenetic gene regulation. Fertilization depends on the proper reception of the pollen tube by the synergid cells, where the pollen tube arrests growth and ruptures to release the sperm cells. We have shown that receptor-like kinases (RLKs) of the CrRLK1L subfamily play an important role in reproduction, with the FERONIA RLK acting in the female and the two redundant ANXUR (ANX1/2) RLKs in the male gametophyte (Escobar-Restrepo et al., 2007; Boisson-Dernier et al. 2009; Miyazaki et al. 2009). The Arabidopsis genome encodes 17 plant-specific CrRLK1L family members with a multitude of functions in pollen tube reception, pollen tube growth but also phytohormone signalling, mechanosensing and plant defence. The extracellular domain of CrRLK1Ls has similarities with malectin (Boisson-Dernier et al. 2011), suggesting that it may bind carbohydrate moieties, but it was also reported to bind the small, secreted RALF peptide (Haruta et al. 2014; Stegmann et al. 2017). Thus, the functions of CrRLK1Ls are diverse and complex. Using various forward and reverse genetic approaches, we are in the process of identifying additional components in the CrRLK1L signalling cascade, focusing on both upstream and downstream components of this RLK subfamily (Mecchia et al., 2017). I will report on the characterization of new components that regulate pollen tube integrity and growth and provide insights into the structural basis of this signaling pathway.
