MS1 — Brassica oleracea

Summary

BoMS1 (BOLC102_C09P057650.1) on cabbage chromosome 9 encodes a protein with PHD-finger and MS1-like ubiquitin domains, and is associated with DNA binding transcription factor activity and zinc binding. The gene is linked to nuclear localisation and to biological processes including anther wall tapetum morphogenesis, microgametogenesis, pollen wall assembly, meiosis, pollen germination, cellular response to brassinosteroid stimulus, tRNA processing, and upregulation of programmed cell death. Traits associated with BoMS1 include cytoplasmic male sterility and self-incompatibility, and phenotypes include male sterility, pollen viability, anther development, tapetal programmed cell death, and flower fertility. Related genes in other species link the family to tapetum development, pollen fertility, anther morphology, and seed size.
