Tobacco mosaic virus. Pioneering research for a century.

artifactual aggregation involving CLV1.) Their intriguing hypothesis is that the CLV3 protein may in fact be the activating ligand of the CLV1 receptor kinase. This possibility is attractive in that intermolecular associations of protein kinases are known to be instigated in animal systems by the binding of ligands to cell receptors. As the authors point out, the cloning of CLV3 will help to elucidate the signal transduction pathway that is promoted by CLV1 to regulate meristematic function.
