Structural variation at the maize WUSCHEL1 locus alters stem cell organization in inflorescences
Abstract
The WUSCHEL transcription factor promotes plant stem cell proliferation. Here the authors show that the maize Bif3 mutant contains a duplication of the ZmWUS1 locus leading to cytokinin hypersensitivity and overproliferation at the shoot meristem demonstrating the role of WUSCHEL in maize and how structural variation can impact plant morphology.
