NAL1 — Oryza sativa Indica Group

Summary

BGIOSGA017120 (NAL1, also known as OiNAL1 or PAY1) on chromosome 4 of Indica rice encodes a protein containing Nal1_N and Nal1_C domains and a Peptidase_S1_PA domain. The gene is associated with grain number, yield, panicle architecture, plant height, tillering capacity, leaf size and shape, flag leaf width, spikelet number, grain appearance and quality, biomass, and photosynthetic rate. It is linked to gibberellin and brassinosteroid signaling, auxin transport, jasmonic acid, nitrogen content, cell cycle modulation, cell division, stem and leaf vascular tissue pattern formation, internode patterning, and regulation of leaf development. The encoded protein localizes to the cytoplasm. Studies of related genes in other species link the family to grain yield, panicle length, and inflorescence branching.
