Abstract excerpt

BACKGROUND: Arabidopsis sepals must grow in a coordinated and robust manner to achieve consistent size and shape, ensuring proper closure and protecting the developing flower bud. To understand how this robust coordination occurs, we analyze the loss-of-robustness mutant development related myb-like1 (drmy1), which exhibits variable sepal initiation and growth, causing failure of bud closure. Specifically, drmy1...
