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 LEAF1 (NAL1) exerts a multifaceted influence on leaf morphology and crop yield. Recent crystal study proposed that histidine 233 (H233) is part of the catalytic triad. Here we report that unlike suggested previously, H234 instead of H233 is a component of the catalytic triad alongside residues D291 and S385 in NAL1. Remarkably, residue 233 unexpectedly plays a pivotal role in regulating NAL1's proteolytic activity. These findings establish a strong foundation for utilizing NAL1 in breeding programs aimed at improving crop yield.
