Controlled stability of proteins is a highly efficient mechanism to direct diverse processes in plants. A key regulatory system for protein stability is given by the CULLIN‐RING E3 ligases (CRLs).
In this work, MYB43 is identified as a novel target of a CUL4‐DDB1‐PRL1 (PLEIOTROPIC REGULATORY LOCUS 1)‐RING E3 ligase (CRL4PRL1 E3 ligase). Its stability depends on the presence of PRL1, a WD40‐containing...
