Genotypic Variation and Relationships between Quality Traits and Trace Elements in Traditional and Improved Rice (Oryza sativa L.) Genotypes

Abstract: In this study, we assessed the extent of genotypic differences among rice genotypes for grain size, milling quality, cooking properties, protein, and the mineral contents of Fe, Zn, Mn, and Cu in unpolished rice varieties. Further, relationship among grain quality traits and mineral contents was determined. The results showed that the visible difference could be found in the mineral contents among rice genotypes studied. The contents of Fe and Zn in traditional genotypes were significantly higher than those of improved cultivars. There was a negative correlation between grain yield and mineral contents. However, Fe, Zn, Mn, and Cu contents appeared to be positively correlated. The relationships between mineral element contents and cooking quality traits viz., kernel length after cooking and kernel linear elongation ratio were positively correlated, indicated the role of micronutrients in cooking quality traits. Both Fe and Cu contents were correlated positively and significantly with head rice recovery. The eigen values of 1st 6 principal components (PC) were > 1.0. The present study suggests that breeding for high minerals will be probably realistic.

Effect of taurine on biomarkers of oxidative stress in tissues of fructose-fed insulin-resistant rats.

Abstract: Introduction The present study was designed to investigate whether taurine mitigates fructose-induced oxidative stress in rat tissues such as heart and kidney. Methods Male Wistar rats of body weight 170-190 g were divided into four groups containing six rats each. Control animals received the control diet containing starch while fructose-fed animals received a fructose-enriched diet (greater than 60 percent of total calories). Fructose and taurine rats received the fructose diet and two percent taurine solution to drink. Control and taurine rats received the control diet and two percent taurine solution. After the treatment period of 30 days, insulin resistance index, by homeostasis model assessment (HOMA) was determined. The levels of lipid peroxidation markers, the enzymatic and non-enzymatic antioxidants status in heart and kidney tissues were measured. Results Fructose rats showed high values of HOMA, increased lipid peroxidation and impaired antioxidant status. Taurine treatment to fructose rats attenuated the increased lipid peroxidation, enhanced the levels of antioxidants and improved insulin sensitivity. Conclusion Inhibition of peroxidation markers and upregulation of antioxidant activity in rat tissues by taurine signify the potential utility of taurine as an adjunct in treatment of insulin resistance.
