HMG — Asparagus officinalis

Summary

A4U43_C03F29710 (AoHMG) encodes a protein containing an HMG-box domain and is a component of the FACT complex, with molecular functions including nucleosome, histone, DNA and protein binding, as well as DNA-binding transcription factor activity. In asparagus, this gene is associated with excretion, karyogamy, polar nucleus fusion, system development, DNA replication and repair, DNA-dependent transcription, cholesterol metabolism, and the transition from vegetative to reproductive phase. It localises to the FACT complex, euchromatin, nucleolus and nucleus. AoHMG is linked to traits including flowering time, anthocyanin content, plant growth and development, and vegetative-to-reproductive phase transition, as well as phenotypes such as seed dormancy, reduced leaf size, early flowering and reduced fertility. Related genes in other species are linked to plant development, genomic imprinting and DNA demethylation.
