NAL1 — Oryza sativa Indica Group

Summary

BGIOSGA017117 (NAL1, also known as OiNAL1 or PAY1) in indica rice chromosome 4 encodes an N-acetyl-glutamate semialdehyde dehydrogenase with argininosuccinate lyase, N-acetyl-gamma-glutamyl-phosphate reductase, and acetylglutamate kinase activities, binding NADP+, NAD, and ATP. The gene is associated with grain number, yield, panicle, distance between small vascular bundles, breeding, growth, dwarf, tillering capacity, leaf nitrogen content, leaf thickness, grain appearance, tiller angle, panicle number, nitrogen content, leaf chlorophyll content, root volume, leaf length, spikelet number, leaf shape, tiller number, photosynthetic rate, chlorophyll content, and plant height. NAL1 is linked to stem vascular tissue pattern formation, internode patterning, auxin transport, regulation of cell division and leaf development, cell cycle modulation, arginine anabolism, and S phase. It localizes to the cytosol and cytoplasm and is associated with gibberellin, BR, ga, BR signaling, and senescence.
