MS1 — Brassica napus

Summary

BnMS1 (DARMORV10_A10P18540.1) on chromosome A10 of oilseed rape encodes a protein with PHD-finger and zinc-binding domains, belonging to the MS1-like ubiquitin family, and is annotated with DNA binding transcription factor activity. The gene is associated with anther wall tapetum morphogenesis, pollen wall assembly, exine formation, microgametogenesis, meiosis, mitosis, syngamy, pollen germination, programmed cell death, and brassinosteroid response. It localises to the nucleus and is linked to lipid metabolism, cell development, and transcriptional regulation. BnMS1 has been connected to male sterility, pollen viability, anther development, tapetal programmed cell death, flower fertility, and microsporogenesis. Associations with cytoplasmic male sterility and heterosis have also been noted. Related genes in other species link the family to tapetum development, pollen fertility, anther morphology, and seed size.
