MS5 — Brassica napus

Summary

BnMS5 (DARMORV10_C01P27910.1) on chromosome C01 of oilseed rape encodes a member of the MS5/SDI1 protein family and is annotated with protein-binding molecular function. The gene is associated with multiple stages of meiosis, including leptotene, pachytene, meiotic prophase I, and male meiotic nuclear division, as well as microsporogenesis and pollen exine formation. It is linked to negative regulation of translation, the meiotic cell cycle, and developmental processes. The encoded protein 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, seed development, and genomic imprinting.
