GNC — Brassica juncea
Summary
BjGNC (BJUA03G46810S) on chromosome A03 of Indian mustard encodes a GATA transcription factor of the GAT21-like family, containing ZnF_GATA and ZnF_NHR/GATA domains. It binds sequence-specific DNA and transcription cis-regulatory regions, acting as a DNA-binding transcription factor with zinc-binding and protein-binding activities. This gene is associated with the regulation of chlorophyll biosynthesis, chloroplast elongation, and carbohydrate utilization, as well as plant organ senescence, seed development and germination, floral organ development, and the timing of the vegetative-to-reproductive phase transition. It is linked to responses to nitrogen compounds, cytokinin, and glucose-mediated signaling, and localizes to the nucleus and Sin3-type complex. Associations with plant height, flowering time, germination rate, root morphology, and meristem identity have been noted. Studies of related genes in other species connect the family to chloroplast biogenesis, leaf senescence, starch synthesis, and flowering time regulation.
