Outline of Final Research Achievements

Deepwater rice elongates its internodes in response to increasing water level to keep its leaves above the water surface and avoid anoxia. We investigated the molecular mechanism of internode elongation in deepwater rice. By genetic and physiological studies, we identified two genes (SK3 and SK4) which regulate internode elongation in deepwater rice. SK3 encodes unknown protein and it is highly expressed in the internode. SK4 encodes a gibberellic acid (GA) biosynthetic enzyme and it is also expressed in the internode. The GA biosynthetic activity of SK4 protein in deepwater rice was significantly higher than that of non-deepwater rice. The SK4 expression in the internode drives GA accumulation. We hypothesize that SK3 in the internode enhances cell division and SK4 driven GA accusation, induces cell elongation. The respective function of SK3 and SK4 in the cell division and cell elongation may explain internode elongation in deepwater rice.
