Abstract
Cardamine hirsuta is a crucifer closely related to the model organism Arabidopsis thaliana. Its leaf morphology differs from Arabidopsis as the leaf blade is fully dissected into distinct units (leaflets). This is reminiscent of phenotypes conditioned in Arabidopsis by misexpression in leaves of Knotted1-like homeobox (KNOX) genes. We have demonstrated that KNOX protein is expressed within leaf primordia of Cardamine. This is in contrast to Arabidopsis where KNOX protein is excluded from leaves. Using a reverse genetics approach we will determine the precise role of KNOX genes in the elaboration of dissected leaf morphology in Cardamine. We will also investigate the molecular basis for the different expression pattern of KNOX genes in Arabidopsis and Cardamine. Our work will help understand how modifications of leaf development programmes in different taxa lead to the elaboration of distinct plant morphologies.
