HAP1 — Oryza sativa Indica Group

Summary

BGIOSGA027851 (symbol HAP1, also known as OiHAP1, OiMEE63, OiMAGO2, and MAGO) on chromosome 8 of Indica rice encodes a Mago nashi family protein with translation initiation factor activity, protein dimerization activity, RNA and mRNA binding, DNA-binding transcription factor activity, and protein binding. This gene is associated with nonsense-mediated mRNA decay, mRNA transport, translation initiation and regulation, RNA splicing, the MAPK cascade, water transport, demethylation, diterpenoid anabolism, response to low humidity and hypoxia, guard cell fate commitment and differentiation, and pollen tube guidance. It is linked to grain yield, grain width, grain length, grain weight, seed weight and size, amylose content, shoot and root dry weight, root length, days to flowering, anthesis time, heat, cold and drought tolerance, chlorophyll content, jasmonic acid content, and stomatal complex closure time. The product localizes to the exon junction complex, nuclear speck, nucleolus, plant-type cell wall, plasmodesma, plastid, mitochondria, and cytosol.
