Research Topic

Environmental control of morphogenesis in plants

Plants are sessile organisms that have to cope with the environment they are exposed to. Several developmental mechanisms are synchronized with the environment, like seed germination or the transition to flowering. We are interested in leaf development and how the environment can interfere with this complex process. We are analyzing the function of class III HD-ZIP transcription factors (HD-ZIPIII). The analysis of target genes of the HD-ZIPIII protein REVOLUTA (REV) revealed several factors that in addition to REV also respond to hormonal and environmental stimuli. Current work is to elucidate the function of some of these target genes and to place these into the regulatory network of genes controlling leaf development in Arabidopsis.
