| Abstract: | A gene
OsZnI encoding Cys3/His1-type zinc
finger protein was isolated from the water stress-induced cDNA library of rice (Oryza sativa) cv.
N-22, an
early maturing, deep-rooted, drought-tolerant genotype adapted to upland
conditions. The in-silico analysis revealed an insert of 800 bp with an ORF of 663 nucleotides,
encoding 221 amino acids. OsZnI had
three distinct features — nuclear localization signal (NLS) present in
Arg152-Arg168, Zn finger domain between 185-193 amino acids and 12 amino acids
conserved domain in 71-82 amino acids homologous to LEA motif, and belonged to
C-type family of Zn finger protein. OsZnI showed induced expression
under water deficit stress. |
