NAL1 — Oryza sativa Japonica

Summary

Rice NAL1 (OS04G0615000) on chromosome 4 encodes a protein with Nal1_N and Nal1_C domains and a Peptidase_S1_PA domain. The gene is associated with gibberellin, brassinosteroid, auxin, abscisic acid, ethylene, jasmonic acid and lignin metabolism, as well as stem and leaf vascular tissue pattern formation, internode patterning, leaf development, cell cycle modulation, anaphase, S phase, translation, and proteasome degradation. It has been linked to grain number, grain weight, grain width, grain yield per plant, panicle length, tiller number, plant height, leaf shape, leaf length, leaf number, flag leaf width, leaf nitrogen content, chlorophyll content, photosynthetic rate, amylose content, inflorescence branching, dwarfism, growth, and biomass. The protein localises to the cytoplasm. Studies of related genes in other species connect the family to auxin transport and plant architecture.
