MS5 — Brassica napus

Summary

BnMS5 (MS5, TDM1) on chromosome A03 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 with microsporogenesis, pollen exine formation, and the negative regulation of translation. It is linked to heterosis and to phenotypes such as cell cycle transitions, meiotic progression, meiosis termination, and gametophytic development. The encoded protein localises to the nucleus and P bodies. Studies of related genes in other species connect the family to meiotic exit, male fertility, genomic imprinting, and seed development.
