MS1 — Brassica napus

Summary

BnMS1 (DARMORV10_C09P54390.1) on chromosome C09 of oilseed rape encodes a nuclear-localised zinc-finger protein of the MS1-like ubiquitin family, with DNA-binding transcription factor activity and zinc-binding capability. The gene is associated with anther wall tapetum morphogenesis, pollen wall assembly, pollen exine formation, microgametogenesis, meiosis, syngamy, and programmed cell death, as well as cellular responses to brassinosteroid stimulus and lipid metabolism. It has been linked 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 recorded. Related genes in other species connect the family to tapetum development, pollen fertility, anther morphology, and seed size.
