malfunction a gln1-1:gln1-2 double mutant shows impairment of seed germination and seedling establishment, phenotype, overview Arabidopsis thaliana
malfunction enzyme mutants, single mutant gln1-2 and gln1-1:gln1-2 double mutant, show impairment of seed germination and seedling establishment. The negative effect of Gln1-2 deficiency, causing slower seedling development in the mutants, is associated with reduced N remobilization from the cotyledons and can be fully alleviated by exogenous N supply. Phenotypes, overview Arabidopsis thaliana
physiological function specific roles of the individual GS1 isogenes with respect to nitrogen remobilization, early seedling vigour, and final seed productivity. Isozyme Gln1-2 plays an important role in N remobilization for both seedling establishment and seed production in Arabidopsis thaliana Arabidopsis thaliana
