Evaluation of Tolerance to Drought Stress in Rice Genotypes (Oryza sativa L.) from Central and West Asian Countries

For 24 rice (Oryza sativa L.) varieties, genetic variation was studied of the Lox3 gene in samples of the two subspecies, japonica and indica. The genomic DNA was amplified, followed by DNA sequencing to detect sequence variation. A total of 13 single nucleotide polymorphisms (SNPs) was detected in the exon 4 containing lipoxygenase domain. The nucleotide diversity in the Lox3 region of O. sati...
