BS1 — Glycine max

Summary

GmBS1 (GLYMA_04G172500V4) encodes a basic helix-loop-helix (bHLH) domain-containing protein with DNA-binding transcription factor activity, protein dimerization activity, and transcription cis-regulatory region binding. It is associated with the regulation of brassinosteroid-mediated signaling, response to brassinosteroid, and regulation of seed size, as well as embryonic root morphogenesis, organ growth, and regulation of leaf development. The gene has been connected to seed size, leaf size, days to maturity, amino acid content, seed coat color, and brassinosteroid sensitivity. It is also linked to root initiation, lateral root development, and plant height. The protein localizes to both the cytoplasm and nucleus. Studies of related genes in other species link the family to hypophysis division and root development, and to plant height.
