Smith, Adrienne H. K. Roeder The growth and division of cells in plant leaves is highly dynamic in time and space, even though cells cannot move relative to their neighbors. Thus, organ shape must emerge from carefully coordinated growth, especially in leaves that remain relatively flat as they grow. Here we explored the phenotype of the jagged and wavy ( jaw-D ) mutant in Arabidopsis thaliana , in which the leaves do not remain flat. It has previously been shown that the jaw-D mutant phenotype is caused by the overexpression of miR319 , which represses TCP transcription factors, thus delaying matur
