Characterization of a putative S-locus encoded receptor protein kinase and its role in self-incompatibility. Progress report
The major results of our research effort include the determination of the S-Receptor Kinase (SRK) gene structure, the demonstration of S-haplotype-associated SRK polymorphisms and possible co-evolution of SRK and SLG, the characterization of the temporal and spatial expression patterns of SRK, and the demonstration that SRK has intrinsic serine/threonine kinase activity. Our results have indicated that SLG originated from an SRK-like gene by a gene duplication event and suggested a possible molecular basis for leaky S haplotypes. The data have allowed us to develop a model of self-incompatibility based on the interaction of SRK and SLG and the activation of SRK in response to self-pollination. More generally, the information that we have obtained is potentially relevant to understanding mechanisms of signalling inplants. Thus, the interaction of membrane-based receptor protein kinases with secreted forms of their extracellular domains may represent a generalized mechanism by which receptors signal across the plant cell wall.
