GLN — Nicotiana attenuata

Summary

A4A49_36137 (GLN, GLNA) encodes a glutamine synthetase (EC 6.3.1.2) with a Gln_synth_cat_dom domain. In coyote tobacco, this gene is associated with glutamine biosynthesis, nitrate assimilation, ammonia assimilation, leaf development and senescence, cell death, response to water, cadmium, and blue light, as well as regulation of gene expression and sumoylation. It is linked to traits including photosynthetic rate, chlorophyll content, root dry weight, flowering time, proline and cytokinin content, stomatal opening, and respiration rate. Related genes in other species have been connected to nitrogen remobilization, seed yield, germination, ammonium homeostasis, salt and cold stress tolerance, and plant defense.
