VASCULATURE COMPLEXITY AND CONNECTIVITY required for bilateral symmetry but not for dorsoventrality in Arabidopsis leaves

, , ,
The formation of the lobes at the Arabidopsis leaf margin are due to differences in local auxin accumulation, coordinated by auxin efflux carrier (PIN1) and transcriptional regulator (CUC2), but the molecular mechanisms acting upstream are not yet understood. Among viable leaf shape mutants, Wilson-Sanchez…
