Function

NAL1_ORYSJ Involved in the regulation of lateral leaf growth (PubMed:18562767, PubMed:22179305, PubMed:23985993). May be involved in the regulation of basipetal polar auxin transport (PAT) and vascular patterning in leaves (PubMed:18562767). Controls photosynthesis rate by regulating carboxylation efficiency and consequently photosynthesis rate (PubMed:23985993). Controls panicle and spikelet numbers, and grain yield (PubMed:23985993, PubMed:24297875, PubMed:24795339).^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

NARROW LEAF 1 (NAL1) is a breeding-valuable pleiotropic gene that affects multiple agronomic traits in rice, although the molecular mechanism is largely unclear. Here, we report that NAL1 is a serine protease and displays a novel hexameric structure consisting of two ATP-mediated doughnut-shaped trimeric complexes. Moreover, we identified TOPLESS-related corepressor OsTPR2 involved in multiple growth and development processes as the substrate of NAL1. We found that NAL1 degraded OsTPR2, thus modulating the expression of downstream genes related to hormone signalling pathways, eventually achieving its pleiotropic physiological function. An elite allele, NAL1(A), which may have originated from wild rice, could increase grain yield. Furthermore, the NAL1 homologues in different crops have a similar pleiotropic function to NAL1. Our study uncovers a NAL1-OsTPR2 regulatory module and provides gene resources for the design of high-yield crops.
