HMG — Brassica juncea

Summary

BjHMG (BJUB04G48120S) on Indian mustard chromosome B04 encodes a protein with an HMG-box domain and belongs to the SSRP1/POB3 family, a component of the FACT complex. The product exhibits nucleosome, histone, DNA, and protein binding activities, as well as DNA-binding transcription factor activity. It localises to the nucleus, nucleolus, euchromatin, and the FACT complex. BjHMG is associated with the mevalonate pathway, isoprenoid, sterol, and glucosinolate anabolism, membrane biogenesis, DNA replication and repair, cell division, karyogamy, polar nucleus fusion, seed germination, cell death, and the transition from vegetative to reproductive phase. It has been connected to flowering time, anthocyanin content, seed dormancy, leaf size, fertility, and overall plant growth and development traits. Studies of related genes in other species link the family to plant development, DNA demethylation, and genomic imprinting.
