MS5 — Brassica napus

Summary

BnMS5 (MS5) on chromosome A10 of oilseed rape encodes a protein of the MS5/SDI1 family and is annotated with protein binding activity. The gene is associated with multiple stages of meiosis, including leptotene, pachytene, meiotic prophase I, and male meiotic nuclear division, as well as microsporogenesis, pollen exine formation, and negative regulation of translation. It localises to the nucleus and P bodies. Associations with heterosis, cell cycle transitions, meiotic progression, meiosis termination, gametophytic development, and meiotic division have been reported. Studies of related genes in other species link the family to meiotic exit, male fertility, male sterility with abnormal pollen division after meiosis, genomic imprinting, and seed development.
