ABS7 — Hordeum vulgare subsp. vulgare

Summary

HvABS7 (HORVU.MOREX.R3.1HG0069820) on barley chromosome 1H encodes a protein with a Myb domain and SANT/Myb domain, and has DNA binding transcription factor activity and sequence-specific DNA binding. The gene is associated with anther wall tapetum morphogenesis, protein storage vacuole organization, pH reduction, regulation of leaf morphogenesis, regulation of endosperm development, seed maturation, starch metabolism, and upregulation of programmed cell death. It localizes to the nucleus and pollen tube. Associations include grain weight, plant height, anthesis time, starch content, protein content, meristem identity, drought tolerance, male fertility, seed germination, ABA sensitivity, root growth, and susceptibility to root-knot nematode. Related genes in other species link the family to gibberellin signaling, anther development, flowering time, aluminium tolerance, grain size, and cold tolerance.
