• Partial submergence greatly stimulates internodal growth in deepwater rice (Oryza sativa L.). Previous work has shown that the effect of submergence is, at least in part, mediated by ethylene, which accumulates in the air spaces of submerged internodes. To investigate the expression of the genes encoding ethylene biosynthetic enzymes during accelerated growth of deepwater rice, we cloned a 1-aminocyclopropane-1-carboxylate (ACC) oxidase cDNA (OS-ACO1) from internodes of submerged plants and measured the activity of the enzyme in tissue extracts with an improved assay. We found an increase in ACC oxidase mRNA levels and enzyme activity after 4 to 24 h of submergence. Thus, it is likely that ethylene biosynthesis in internodes of deepwater rice is controlled, at least in part, at the level of ACC oxidase.
