ABS7 — Triticum aestivum

Summary

TaABS7 (TRAESCS3A02G336500) on bread wheat chromosome 3A encodes a GAMYB-like transcription factor with sequence-specific DNA binding activity. This gene is associated with anther wall tapetum morphogenesis, floral organ senescence, regulation of leaf morphogenesis, regulation of pollen tube growth, and gibberellin biosynthesis. It is linked to salt tolerance in wheat, as well as to grain weight, grain length, grain protein content, heading time, plant height, flag leaf senescence, and stripe rust and stem rust responses. Additional associations include seed weight, anther length, water use efficiency, transpiration rate, and calcium concentration. 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, male sterility, and aleurone development.
