ABS7 — Hordeum vulgare subsp. vulgare

Summary

HvABS7 (HORVU.MOREX.R3.3HG0296070) on barley chromosome 3H encodes a GAMYB-like transcription factor with sequence-specific DNA binding activity. The gene is associated with anther wall tapetum morphogenesis, protein storage vacuole organization, regulation of endosperm development, starch metabolism, and regulation of phenylpropanoid and lignin anabolism. It has been connected to grain weight, protein content, starch content, anthesis time, plant height, and yield. Associations also include drought tolerance, nitrogen deficiency response, root growth, seed germination, male fertility, and susceptibility to root-knot nematode. The encoded protein localizes to the nucleus, pollen tube, and plant-type cell wall. Studies of related genes in other species link the family to flowering time, gibberellin signaling, anther development, salt tolerance, tillering, seed development, and aluminium resistance.
