GLN — Cucumis melo

Summary

MELO3C020230.2, designated CmGLN on melon chromosome 7, encodes a protein with Gln_synt_N and Gln_synth_cat_dom domains and is annotated with glutamine synthetase activity. The gene is associated with glutamine biosynthesis, nitrate assimilation, and the ammonia assimilation cycle. It has been linked to leaf senescence, flowering time, and responses to abscisic acid, cadmium, and blue light. Associations with starch grain synthesis, photosynthetic rate, respiration rate, and stomatal opening have been noted. The gene is connected to seed yield, seed germination, pollen viability, nitrogen remobilisation, and vegetative growth. Studies of related genes in other species link the family to lateral root development, ammonium tolerance, and circadian rhythm.
