HAP1 — Glycine max

Summary

GmHAP1 (GLYMA_15G097500V4) on soybean chromosome 15 encodes a Mago nashi family protein with translation initiation factor activity, RNA and mRNA binding, protein dimerization activity, and DNA-binding transcription factor activity. The gene is associated with plastid localization, mRNA transport, RNA splicing, nonsense-mediated mRNA decay, translation initiation, and positive regulation of gene expression. It is linked to guard cell fate commitment and differentiation, pollen tube guidance, and responses to hypoxia and low humidity. Associations with glycerolipid, salicylic acid, cytokinin, and fatty acid metabolism have been observed. The gene is associated with seed weight, seed size, stearic and palmitic acid content, protein content, amino acid content, days to flowering, drought tolerance, salt tolerance, and root and flower morphology traits. Related genes in other species are linked to stomatal development and viral accumulation.
