Transcriptome profiling of Arabidopsis thaliana (Col-0) wild type and wox-135 triple mutants

Transcriptome profiling of A. thaliana (Col-0) and wox-135 triple mutants along with genetics and time-lapse growth analysis was done to show that in A. thaliana WOX5, one of the WUSCHEL-RELATED HOMEOBOX (WOX) family of homeobox genes, acts redundantly with WOX1 and WOX3 (PRS) to control leaf shape such that triple wox1 wox3 wox5 mutants have extremely narrow leaves. We find that these WOXes act in part through regional control of YUCCA (YUC) auxin biosynthetic gene expression along the leaf margin.
