GLN — Daucus carota subsp. sativus

Summary

DcGLN (DCAR_031586) on carrot chromosome DCARv2_B16 encodes a protein with a glutamine synthetase catalytic domain and is annotated with glutamine synthetase activity, as well as glutamate-tRNA ligase, histone acetyltransferase, SUMO transferase, and calmodulin binding activities. The gene is associated with the ammonia assimilation cycle, nitrate assimilation, leaf senescence, response to abscisic acid, and regulation of transcription. It is linked to traits including photosynthetic rate, respiration rate, flowering time, starch grain synthesis, and stomatal opening, and to phenotypes such as root development, seed yield, nitrogen remobilisation, ammonium metabolism, and salt and cold stress tolerance. Related genes in other species connect the family to lateral root development, ammonium tolerance, and circadian rhythm.
