Outline of Final Research Achievements

Plant organ growth is mediated by a balanced progression of cell division and differentiation. Plant cells udergo massive transcriptional changes when they transit from proliferateive to differentiation phases but how these modifications in gene expression are regulated is not well understood. From a new genetic screen we have recently identified several putative transcriptional regulators that might mediate these transcriptional responses. In this study we investigated functional roles of these new regulators and we showed that a DOF transcriptional factor OBP4 negatively regulates root hair growth.
