GS2 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0606810 (HvGS2) encodes a growth-regulating factor (GRF) protein containing QLQ and WRC domains and functions as a transcription coactivator. Located in the nucleus, it is associated with seed development, grain filling, leaf senescence, root meristem growth, cell division, photorespiration, and responses to salt, nitrate, deep water, and gibberellin. The gene is linked to grain weight, grain yield, seed weight, water use efficiency, chlorophyll content, anthocyanin content, leaf morphology, and floral organ development. Studies of related genes in other species connect the family to grain size, heat and cold tolerance, organ size, and plant regeneration efficiency.
