HMG — Brassica juncea

Summary

BjHMG (BJUA02G07030S) encodes a protein belonging to the SSRP1/POB3 family, containing an HMG-box domain and domains characteristic of the FACT complex. The product exhibits nucleosome, histone, DNA, and protein binding activities, and has DNA binding transcription factor activity. In Indian mustard, BjHMG is associated with the mevalonate (MVA) pathway, isoprenoid and sterol anabolism, 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 is linked to flowering time, anthocyanin content, leaf size, fertility, seed dormancy, and plant growth and development traits. The protein localizes to the nucleus, nucleolus, euchromatin, and the FACT complex. Studies of related genes in other species connect the family to plant development, DNA demethylation, and genomic imprinting.
