“…The phytochemical compounds and antioxidant activity of rice grain were already reported (Shen, Jin, Xiao, Lu, & Bao, 2009;Chen, Nagao, Itani, & Irifune, 2012). The antioxidant activity of rice bran was investigated extensively (Rohrer & Siebenmorgen, 2004;Iqbal, Bhanger, & Anwar, 2005;Renuka Devi & Arumughan, 2007;Arab, Alemzadeh, & Maghsoudi, 2011).…”

“…ANS was recently detected in rice by homology research 14 . Chen et al 15 reported that black rice contains 3 kinds of anthocyanin pigments; however, red rice contains only one micromolecule anthocyanin pigment (malvidin). Moreover, the content of anthocyanin pigment in black rice was 20-fold higher than that in red rice.…”

Flavonoids play an important role in the grain color and flavor of rice. Since their characterization in maize, the flavonoid biosynthetic genes have been extensively studied in grape, Arabidopsis, and Petunia. However, we are still a long way from understanding the molecular features and mechanisms underlying the flavonoid biosynthetic pathway. The present study was undertaken to understand the physiological factors affecting the transcription and regulation of these genes. We report that the expression of CHI, CHS, DFR, LAR, and ANS, the 5 flavonoid biosynthetic genes in different rice varieties, differ dramatically with respect to the stage of development, white light, and sugar concentrations. We further demonstrate that white light could induce the transcription of the entire flavonoid biosynthetic gene pathway; however, differences were observed in the degrees of sensitivity and the required illumination time. Our study provides valuable insights into understanding the regulation of the flavonoid biosynthetic pathway.

“…Окраска зерновки риса обусловлена наличием и раз-личным соотношением пигментов, содержащихся в пери-карпе, семенной оболочке и алейроновом слое (Dong et al, 2008;Chen et al, 2012;Maeda et al, 2014).

Genetic Resources of Rice (Oryza Sativa L.) With Colored Pericarp

The rice plant (Oryza sativa L.) provides nutrition for more than half the world's population. Traditionally it is considered an Asian crop, but it is also cultivated in Africa, America, Australia and Southern Europe. The main areas of rice growing in the world are occupied with the white-grained varieties. Wild-growing ancestors of cultural rice had a colored grain pericarp. In the countries of traditional rice growing, along with white-grained varieties, red and black grain rice varieties are grown as a dietary and therapeutic product. It is used for food without preliminary grinding of the grains, therefore all nutrients and biologically active substances this culture is valued for are preserved. Rice with the colored grain pericarp has a higher antioxidant activity than white-grained. The review presents data on the content of antioxidant compounds in the varieties of the red-and black-grained rice: phenolic acids, flavonoids, γ-oryzanol, anthocyanins, proanthocyanidins, etc. Aiming at these useful properties of rice plants with a colored grain pericarp, the leading rice-growing countries work on breeding of the modern pigmented rice varieties. In European countries, Italy and France, the red and black grain varieties of rice with a high content of phytochemical elements have also been bred based on Asian varieties. Breeding of rice varieties with colored grain pericarp was started in the Russian Federation in 2001. As a result, the following rice varieties were developed: red-grained Mars and Rubin (2012), as well as the black-grained glutinous variety Yuzhnaya Noch (2014), which are included in the RF State Register of Protected Breeding Achievements. These varieties have been revealed to contain a large amount of oleic and linolenic acids (up to 43 % each), whereas only their traces are found in the white-grained rice variety Rapan. There are significant differences in the content of antioxidants: Rapan has 7 mg/100 g; Mars and Rubin, 45 mg/100 g; Yuzhnaya Noch, 105 mg/100 g. These varieties have been introduced into commercial production and are used for dietary nutrition and as a starting material for the creation of new exclusive varieties of rice.Key words: red rice; black rice; rice varieties; hybridization; breeding; antioxidants; anthocyanins; proanthocyanidins; nutritional value.Рис посевной (Oryza sativa L.) обеспечивает питание более полови ны населения Земли. Традиционно он считается азиат-ской культу рой, но возделывается также в Африке, Америке, Австралии и Южной Европе. Основные площади посева риса в странах мира занимают белозерные сорта. Дикорастущие предки культурного риса имели окрашенный перикарп зерна. В странах традиционного рисоводства наряду с белозерными сортами выращивают крас нозерный и чернозерный рис для использования в качестве дие тического и лечебного продукта. Его употребляют в пищу без предварительного шлифования крупы, поэтому сохраняются все питательные и биологически активные вещества, которыми ценит ся эта культура. Рис с окра-шенным перикарпом зерна обладает более выс...
