Comparisons of protein, lipid, phenolics, γ-oryzanol, vitamin E, and mineral contents in bran layer of sodium azide-induced red rice mutants

Abstract: The brans of M-18, M-50 and M-56 are good sources of proanthocyanidins, vitamin E and γ-oryzanol, respectively, while the bran of M-54 is rich in Fe. Thus these mutants could be used to produce high-value phytochemicals or Fe byproducts from bran during rice grain milling or as genetic resources for rice improvement programs.

“…Sodium azide is a chemical mutagen that creates point mutation in the genome of plants by producing metabolite, which consequently produces protein in mutant plants that have different functions from the normal plant (Al-Qurainy and Khan, 2009). This technique has been used to improve the Fe content in the bran part of colored rice (Jeng et al, 2011). In this study, high variability in the Fe contents of the polished grains of the wild type variety IR64 and its NaN 3 -induced mutants was observed (Fig.…”

“…sodium azide (NaN 3 ) and ethyl methanesulphonate) mutagenesis has been used to create genetic variability and improve some agronomic traits (Tai, 2007;Jeng et al, 2011). Therefore, it is worthwhile to use this technique to increase genetic diversity in some of important rice varieties and, subsequently, increase the iron content in their polished grains.…”

“…The content of total flavonoids was expressed as g quercetin equivalent kg −1 dry plant material, with quercetin used in the construction of the standard curve. The content of total anthocyanins was determined using the spectrophotometric method, with cyanidin 3‐ O ‐β‐glucoside used as the standard (Jeng et al ., ). Contents of soluble protein in the prepared polyphenolics‐rich extracts and αAI‐rich extracts were measured using the method of Bradford ().…”
