 ILA1 is a functional kinase with Ser/Thr kinase activity.ILA1 is a key factor regulating mechanical tissue formation at the leaf lamina joint and is involved in mechanical tissue formation in the leaf lamina joint<ref name="ref1"/>.
 ===Expression===
 ILA1 is predominantly resident in the nucleus and expressed in the vascular bundles of leaf lamina joints.ILA1Encodes a Group C Raf-Like MAPKKK with Ser/Thr Kinase Activity<ref name="ref2" />.Thermal asymmetric interlaced PCR show that the increased leaf angle ofila1arises from a T-DNA insertion in Os06g50920.Because nuclear localization is a significant feature of transcription factors, GFP is fused to the N terminus of IIP2 and IIP4 and transformed the rice protoplasts. Detection of thefusion proteins in the nuclei of the transformed cells suggest that IIP2 and IIP4 are nuclear-localized proteins. To confirm the sequence identity ofILA1, a complementation test is performed by transforming theila1 mutant with an 8.8-kbgenomic region that included the complete open reading frame(ORF) and putative promoter region for ILA1 (pILA1). All of the complementation lines show the wild-type leaf inclination,suggesting that Os06g50920 is ILA1.The leaf angle of WT is increased compared that of ila1. But the increased leaf angle of ila1 is not due to altered BR.ILA1 mutation significantly represses the expression of genes involved in cell wall synthesis and consequently causes the increased leaf responses <ref name="ref3" />.ILA1 regulates mechanical strength in the leaf lamina joint.Genome-wide exploration of the expression profiles of ila1 and wild-type leaf lamina joints showed that the expressionof many genes involved in cell wall formation is downregulated in the mutants.Rice leaf angle is one of the important agronomic traits
 affecting plant architecture and yield. Most of the previously documented rice leaf inclination mutants arise from BR-induced cell division and/or elongation at the adaxial surface of the leaf lamina joint. Suppression of BR biosynthesis or signaling generally blocks cell propagation/expansion and results in an erect leaf; in the presence of BR, cell division/expansion occurs and induces an increased leaf angle<ref name="ref4" />.
