Elongation Growth in Internodes of Floating Rice :

Hormonal Regulations and Cell Wall Modifications

Abstract

Floating rice is the only crop that can be grown in flooded plains due to the capacity to elongate internodes rapidly under flooding conditions. The mechanisms of adaptation to flooding stress have been investigated from ecological, morphological, genetical, physiological, biochemical and molecular biological points of view. In this review, we mainly describe our research that has focused on the regulation of growth by plant hormones and the change in cell wall structure during rapid elongation in internodes of submerged floating rice.
