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

General Information
General Information
Commentary
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
