Summary: The growth of leaves is dependent on the extent of the expansion of leaf cells and on cell proliferation. The rates of the division and enlargement of leaf cells at each stage contribute to the final shape of the leaf, and play important roles throughout leaf development. However, the processes controlling these basic aspects of leaf development remain unresolved. Recently, we identified and characterized several genes that regulate leaf expansion. This brief review article focuses on our current study of the genetic mechanisms of leaf expansion in Arabidopsis.
