ABI3 (GLYMA_08G357600V4) — Glycine max

Summary

GLYMA_08G357600V4, designated GmABI3 (also GmSIS10), encodes a LEC2-like protein containing a B3 DNA-binding domain. The product exhibits sequence-specific DNA binding, transcription coactivator activity, and associations with Hsp90 binding, phytochrome binding, and ubiquitin-protein transferase activity. In soybean, GmABI3 is associated with positive regulation of seed maturation, seed growth, petal morphogenesis, and responses to gibberellin, trehalose, and oomycetes. It is associated with numerous agronomic traits including seed protein content, seedling vigor, vegetative vigor, seed set percent, iron content, cadmium concentration, phosphorus uptake, photoperiod sensitivity, water stress response, and aphid response. The gene is also linked to seed storage protein expression. Studies of related genes in other species link the family to seed longevity, desiccation tolerance, oil accumulation, and ABA responsiveness.
