Arabidopsis thaliana during seed germination, the expression of the enzyme decreases until the cotyledons expand out of the seed coat down

General Information

General Information Comment Organism
malfunction a GAMT2null mutant displays ancymidol- and abscisic acid-resistant phenotype in seed germination assay Arabidopsis thaliana
physiological function the enzyme is involved in seed maturation, germination and silique development by modulating gibberellic acid activity. Enzyme overexpression in Arabidopsis results in multiple phenotypes, including dwarfism, retarded growth, late flowering, and reduced fertility Arabidopsis thaliana
