PL — Oryza sativa Indica Group

Summary

BGIOSGA003819 (PL, also known as EGL1, BHLH012, and OiMYC6.2) on Indica rice chromosome 1 encodes a protein with MYC/MYB_N and bHLH domains, possessing DNA-binding, transcription coactivator, protein kinase, and ubiquitin-protein transferase activities. In rice, it is associated with leaf elongation, trichome spacing and morphogenesis, stomatal complex formation, epidermal cell fate specification, proanthocyanidin and mucilage anabolism, and sucrose-mediated signaling. The gene is linked to numerous agronomic traits including grain shape and color, seed set percent, stem dry weight, leaf trichome density, phosphate content, cadmium concentration, UV light sensitivity, plant male sterility, and lignin and gibberellin biosynthesis traits. It localizes to the nucleus, cytoplasm, plasmalemma, mitochondria, root hair, and vesicle. Studies of related genes in other species connect the family to trichome and root hair development, anthocyanin production, seed oil accumulation, and stress responses.
