Annotated Information
Function
Map-based cloning revealed thatNAL2andNAL3are paralogs that encode an identical OsWOX3A (OsNS) transcriptional activator, homologous to NARROW SHEATH1 (NS1) and NS2 in maize and PRESSED FLOWER in Arabidopsis.OsWOX3Ais expressed in the vascular tissues of various organs, wherenal2/3mutant phenotypes were displayed. Expression levels of several leaf development-associated genes were altered innal2/3, and auxin transportrelated genes were significantly changed, leading topinmutant-like phenotypes such as more tillers and fewer lateral roots.OsWOX3Ais involved in organ development in rice, lateral-axis outgrowth and vascular patterning in leaves, lemma and palea morphogenesis in spikelets, and development of tillers and lateral roots. Please input function information here.
Expression
The ricenarrow leaf2andnarrow leaf3loci encode WUSCHELrelated homeobox 3A (OsWOX3A) and function in leaf, spikelet,tiller and lateral root development.nal2/3 mutation negatively affects both vegetative and reproductive organ development with a severe loss of grain yield. Please input expression information here.
