MS5 — Brassica napus

Summary

BnMS5 (DARMORV10_A02P38940.1) on chromosome A02 of oilseed rape encodes a member of the MS5/SDI1 protein family. The gene product is associated with protein binding and localises to the nucleus and P bodies. It has been linked to multiple meiotic processes including leptotene, pachytene, meiotic prophase I, male meiotic nuclear division, and the meiotic cell cycle, as well as microsporogenesis, pollen exine formation, and negative regulation of translation. Associations with heterosis have also been noted. Studies of related genes in other species link them to meiotic exit, male fertility, seed development, and genomic imprinting, with further connections to pollen fertility restoration and seed growth traits.
