MS5 — Brassica napus

Summary

BnMS5 (DARMORV10_A03P64520.1) on chromosome A03 of oilseed rape encodes a protein with protein-binding activity. This 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 negative regulation of translation. It is linked to the nucleus and P-body localisation. Associations with heterosis, cell cycle transitions, meiotic progression, meiosis termination, gametophytic development, and meiotic division have been noted. Studies of related genes in other species link the MS5/SDI1 family, which contains TPR domains, to male fertility, meiotic exit, seed development, and genomic imprinting.
