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...

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

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Rapid progress in comparative genomics among the grasses has revealed similar gene content and order despite exceptional differences in chromosome size and number. Large- and small-scale genomic variations are of particular interest, especially among cultivated and wild species, as they encode rapidly evolving features that may be important in adaptation to particular environments. We present a...

Rice (Oryza sativa L.) can produce black grains as well as white. In black rice, the pericarp of the grain accumulates anthocyanin, which has antioxidant activity and is beneficial to human health. We developed a black rice introgression line in the genetic background of Oryza sativa L. 'Koshihikari', which is a leading variety in Japan. We used Oryza sativa L. 'Hong Xie Nuo' as the donor paren...
