“…A black rice line has been developed in the genetic background of a leading Japanese white rice variety (Koshihikari); which has eating quality superior to that of the widely cultivated black rice variety "Okunomurasaki" (Maeda et al, 2014). Crosses have been initiated between pigmented and non-pigmented varieties to develop pigmented varieties adapted to the growing conditions in Kazakhstan (Rysbekova et al, 2017). The Thai aromatic, deep purple indica-type rice variety "Riceberry" has developed a reputation for its healthpromoting properties.…”

Improving the nutritional quality of rice grains through modulation of bioactive compounds and micronutrients represents an efficient means of addressing nutritional security in societies which depend heavily on rice as a staple food. White rice makes a major contribution to the calorific intake of Asian and African populations, but its nutritional quality is poor compared to that of pigmented (black, purple, red orange, or brown) variants. The compounds responsible for these color variations are the flavonoids anthocyanin and proanthocyanidin, which are known to have nutritional value. The rapid progress made in the technologies underlying genome sequencing, the analysis of gene expression and the acquisition of global 'omics data, genetics of grain pigmentation has created novel opportunities for applying molecular breeding to improve the nutritional value and productivity of pigmented rice. This review provides an update on the nutritional value and health benefits of pigmented rice grain, taking advantage of both indigenous and modern knowledge, while also describing the current approaches taken to deciphering the genetic basis of pigmentation.

“…The second method for scoring Rc was based off the protocol of Rysbekova et al (2017) and used 2 sets of primer pairs: Rc_wtF1 with Rc_wtR1, and Rc_delF3 with Rc_delR3 (Supplementary Table S2). Thermocycler conditions for both reactions were as follows: denaturation at 94 °C for 2 min followed by 40 cycles of denaturation at 94 °C for 30 s, annealing at 54 °C for 30 s, and elongation at 72 °C for 30 s. PCR was finished with elongation at 72 °C for 7 min and held at 4 °C.…”

Weedy relatives of crop species infest agricultural fields worldwide, reducing harvests and threatening global food security. These weeds can potentially evolve and adapt through gene flow from both domesticated crop varieties and reproductively compatible wild relatives. We studied populations of weedy rice in Thailand to investigate the role of introgression from cultivated and wild rice in their evolution. We examined 2 complementary sources of genetic data: allelic variation at 3 rice domestication genes (Bh4, controlling hull color; Rc, controlling pericarp color and seed dormancy; and sh4, controlling seed shattering), and 12 previously published SSR markers. Sampling spanned 3 major rice growing regions in Thailand (Lower North, North East, and Central Plain) and included 124 cultivated rice accessions, 166 weedy rice accessions, and 98 wild rice accessions. Weedy rice strains were overall closely related to the cultivated varieties with which they co-occur. Domestication gene data revealed potential adaptive introgression of sh4 shattering alleles from wild rice. Introgression of potentially maladaptive rc crop alleles (conferring reduced dormancy) was also detected, with the frequency of the crop allele highest in northern populations. Although SSR markers also indicated introgression into weed populations from wild and cultivated rice, there was little overlap with domestication genes in the accessions showing admixed ancestry. This suggests that much of the introgression we detected at domestication genes most likely reflects past introgression rather than recent gene flow. This finding has implications for understanding long-term gene flow dynamics between rice and its weedy and wild relatives, including potential risks of transgene escape.

“…Based on cell and tissue culture methods, perspective lines of wheat, barley, sorghum, rape, safflower and rice with economically valuable traits are created for inclusion in breeding programs, aiming at the creation of new varieties (Rysbekova et al 2016;Zhambakin et al 2014).…”

Biotechnological methods are becoming an integral part of biological research. This review presents some of the most significant scientific results of Kazakhstan biologists in the field of plant biotechnology over the past 10 years. One of the recent important areas of application of biotechnological methods is the conservation and study of plant genetic resources and bioremediation. Studies on the flora lead to the identification of new sources of previously unknown biologically active materials, especially among wild plants growing in Kazakhstan. In addition, various biotechnological approaches are used to increase the efficiency of breeding practices for the production of new crop varieties.
