MS5 — Brassica napus

Summary

BnMS5 (DARMORV10_C07P51000.1) on chromosome C07 of oilseed rape encodes a protein containing MS5/SDI1 and tetratricopeptide repeat (TPR) domains, 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 have been noted. Studies of related genes in other species link the family to meiotic exit, male fertility, seed development, and genomic imprinting, while sequence similarity connections extend to pollen fertility restoration and cell cycle traits.
