Abstract
Coordinated regulation of the many genes controlling leaf, flower, and root development determines the pheno-types of plants; this regulation requires exquisite control of many transcription factors, including the WuSChEL-related homeobox (WoX) family. We recently reported that rice (Oryza sativa) WuSChEL-related homeobox 3a (osWoX3a) plays important roles in organ development, including lateral-axis outgrowth and vasculature patterning in leaves, lemma and palea morphogenesis in spikelets, and the numbers of tillers and lateral roots. osWoX3a is encoded by NARROW LEAF2 (NAL2) and NAL3, a pair of duplicated genes. in this study, further analysis of nal2 nal3 (hereafter nal2/3) double mutants revealed that, in addition to its role in lateral root development, osWoX3a also acts in the control of root hair formation. Based on this new fnding, we describe a possible mechanism by which osWoX3a regulation of auxin transport genes acts in root development. ⓒ 2013 Landes Bioscience.
