Expression of -Expansins Is Correlated with Internodal Elongation in Deepwater Rice
Fourteen putative rice (Oryza sativa) -expansin genes, Os-EXPB1 through Os-EXPB14, were identified in the expressed sequence tag and genomic databases. The DNA and deduced amino acid sequences are highly conserved in all 14 -expansins. They have a series of conserved C (cysteine) residues in the N-terminal half of the protein, an HFD (histidine-phenylalanine-aspartate) motif in the central regi...

متن کاملThe biophysical basis of elongation growth in internodes of deepwater rice.
Partial submergence induces rapid internodal elongation in deepwater rice (Oryza sativa L., cv Habiganj Aman II). We measured in vivo extensibility, tissue tension, hydraulic conductance and osmotic potential in the region of cell elongation in the uppermost internode. The in vivo extensibility of the internode, measured by stretching of living tissue with a custom-made constant stress extensio...
متن کاملRice growth adapting to deepwater.
Flooding is one of the most hazardous natural disasters, and there are several levels of flooding. Recently, research on flood-tolerant rice plants revealed that some rice varieties have evolved to overcome two different flood types, 'flash flood' and 'deepwater flood', using two different mechanisms, and their molecular mechanisms were determined. During flash flooding, the tolerant plants tha...
متن کاملGenetic Divergence in Deepwater Rice Genotypes
The nature and the magnitude of genetic divergence was estimated in 35 deepwater rice genotypes using Mahalonobis’s D2 – statistics. The genotypes were grouped onto 10 clusters showing fair degree of relationship between geographic distribution and genetic divergence. Cluster IV showed maximum intra cluster divergence while inter cluster divergence was maximum between clusters IX and X. All the...
