Function
Alpha-amylase gene, RAmylA, encodes rice α-amylase isoform A.
Expression
A significant difference in the seed germinability was observed between the two rice cultivars, 'Nipponbare' and 'Suweon 287', under anoxia (i.e., during germination in submerged soil at 18℃), although little difference was seen under aerobic (in air) or hypoxic (in water) conditions. The number of α-amylase isoforms synthesized in germinating seeds was inversely proportional to the O2 concentrations at the early germination stage. The formation of isoform B was promoted by oxygen supply, while isoform H was undetectable if the seeds were unable to germinate. The activity of isoform H was highly correlated with the coleoptile length in the submerged soil at 18℃, indicating that isoform H is a critical factor for seed germination under anoxia. The expression of the rice α-amylase RAmy1A gene was repressed when the seeds germinated under hypoxia or anoxia.
Ontology
Gene ontology: The chemical reactions and pathways involve in carbohydrates.
