PL — Oryza sativa Indica Group

Summary

BGIOSGA015472 (PL, also known as EGL1, BHLH012, and MYC6.2) on chromosome 4 of Indica rice encodes a bHLH domain-containing protein with DNA-binding transcription factor activity, protein dimerization activity, and transcription coactivator activity. It is associated with small GTPase binding, ubiquitin-protein transferase activity, and protein serine/threonine kinase activity. The gene is linked to leaf elongation, trichome spacing and morphogenesis, stomatal complex formation, root hair localization, and proanthocyanidin anabolism. It is associated with grain shape, grain color, seed coat morphology and color, thousand-kernel weight, grain filling, stem dry weight, phosphate content, cadmium concentration, UV light sensitivity, plant male sterility, and biotic stress traits. Related genes in other species link the family to trichome development, root hair cell differentiation, seed oil accumulation, and UV-B stress response.
