ABS5 — Glycine max

Summary

GLYMA_10G205000V4, designated GmABS5, encodes a basic helix-loop-helix (bHLH) transcription factor with DNA binding, protein dimerization and homodimerization activities. The product belongs to the AIG1-like and bHLH domain families. In soybean, GmABS5 is associated with stele and stigma development, meristem initiation, epidermal cell fate specification, and metabolism of vitamins A, B6, riboflavin, folate, ALA, glycerolipids, and mycose. It is linked to numerous agronomic traits including seed weight, seed coat color and morphology, root nodule number, root volume, root hair length, leaf trichome density, leaf water potential, chlorophyll content, anthocyanin content, flowering time, heterosis, and responses to biotic and abiotic stress. The gene localizes to both the cytoplasm and nucleus. Studies of related genes in other species connect this gene family to vascular development, root hair patterning, trichome formation, anthocyanin pigmentation, and seed coat pigmentation.
