Cloning and characterization of a gene encoding novel zinc finger protein transcription factor induced under water deficit stress from rice (Oryza sativa) cv. N-22.

摘要: 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 insert 800 bp with ORF 663 nucleotides, 221 amino acids. had three distinct features--nuclear localization signal (NLS) present in Arg152-Arg168, Zn domain between 185-193 acids and 12 conserved 71-82 homologous LEA motif, belonged C-type family protein. showed induced expression under deficit stress.
