Genetic analysis of cell-expansion processes in leaves of Arabidopsis thaliana

Abstract

Arabidopsis thaliana(L.)Heynh. is an excellent model for studies of developmental genetics in plants. We have focused on the developmental genetics of leaf morphogenesis of Arabidopsis and several important processes in leaf morphogenesis have discovered from analyses of mutants in leaf morphology. This review summarizes our current understanding of the genetic mechanisms that regulate the expansion of leaf cells in Arabidopsis.
