“…By using knockdown mutants, OsMIT on chromosome 3 has been detected to be associated with Fe accumulation in rice grains [20]. Genome editing method, such as CRISPR/Cas9 has been applied for Fe bio-fortification in rice grains [21,160,239,240,241]. Four candidate genes which identified by GWAS, including OsFAD2_1, LOC_Os02g32490, OsNHX2, and OsHKT1;5 related to Na and K concentration in rice grains [174].…”

Rice (Oryza sativa L.) is primary dietary source for half of the global population that comprising both essential nutrients and toxic heavy metal elements for human health. A number of nutrients are required within the diet and generally lacking in human diets, and need to biofortify into the rice grains, such as iron (Fe), zinc (Zn), calcium (Ca), potassium (K), sodium (Na), magnesium (Mg), phosphorus (P), copper (Cu), iodine (I), selenium (Se), and Sulphur (S). Meanwhile, some elements are toxic to human, including arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), mercury (Hg), manganese (Mn), nickel (Ni), and lead (Pb) which need to be eliminated from the rice grains. This article reviews the aspects of phenotypic variation of grain elemental concentration in the diverse rice genotypes, relationship of environmental conditions and rice grain elemental accumulation, correlation between rice grain elemental content and others agronomic traits, and also genetic basis of grain elemental concentration in rice. All of these aspects are important to develop rice varieties with a balanced elemental nutrients and lower toxic heavy metal elements. Enhancing the concentration of essential mineral elements and reducing the accumulation of toxic elements in the rice grain are important to improve the rice quality for human health in addressing mineral deficiency and toxicity that could be accomplished by using plant breeding, agronomic, and genetic engineering approaches.

“…The mutation techniques used two different kinds of mutagen, gamma (γ) irradiation with different doses (100Gy and 150Gy) and sodium azide (SA) along with variety soaking time (2 and 6 hours), and also combination of γ irradiation and sodium azide (Table 4 and 5). Several studies reported that the induction mutation techniques with γ irradiation, sodium azide, and their combination increase the grain yield up to 7-40% [36][37][38] and can increase the drought resistance in the level -0.0021 to -0.0077 MPa [39][40][41]. Based on the vegetative and reproductive performance of mutated Rojolele under drought, the best techniques to mutate Rojolele can be determined and used to develop drought resistance Rojolele rice cultivar.…”

Rojolele is an Indonesian traditional rice variety from Klaten (Central Java) that classified as tropical japonica and low land rice which become a premium rice variety and have higher price in the market due to a delicious taste and a fragrance aroma. The agronomic characteristics of Rojolele are having high plant stature with sturdy stems and upright plant shape, thick and rough leaves, strong and deeper root systems, long panicle length, and long duration of life. Rojolele rice cultivation is facing important challenges from drought, diseases, long duration, and lodging. Thus, breeding Rojolele cultivars with resistance to drought, diseases, lodging, and short duration is the major focus for Rojolele rice improvement. Indonesian farmer have learned to successfully cultivate Rojolele by applying practical skills, leading to increase the rice productivity. Molecular breeding program, including quantitative trait loci (QTL), genome-wide association study (GWAS), genomic selection, and genome editing can be applied to improve Rojolele characteristics. In this review, important agronomic and quality traits, intensification system for irrigation and pest control, mutation breeding, transgenic lines, and also future perspectives for Rojolele research were presented. Rojolele is useful for rice breeding program in order to guarantee the food security to overcome increasing population and climate change.

“…There are various kinds of rice are consumed that can be classified based on the grain color into black, red, purple, brown, green, and white [6][7][8][9]. White rice is generally consumed, while pigmented rice, such as black, red, purple, and brown contain natural pigment anthocyanins that accumulate in the particular layers of the seed coat, pericarp, and aleurone [10][11][12][13][14][15][16][17][18]. Total anthocyanins in each pigmented rice varieties are diverse in the range of 0-493 mg/100 g [19].…”

Rice (Oryza sativa L.) is the primary staple food for half of the world population. It is generally classified based on the grain color into black, red, purple, brown, green, and white. These colored rice are determined by the composition and concentration of anthocyanin pigments in different layers of aleurone, pericarp, and seed coat. Anthocyanins are also accumulated in various tissues of the rice plants, mostly in the grain, but are also presents in leaves, leaf sheath, floral organ, and hull. The type and concentration of the anthocyanins in rice tissues are influenced by the cultivars and developmental stages. Anthocyanin-enriched rice is related to the health effects, including antioxidant, antibacterial, and anti-inflammation activities that potentially use as functional food ingredients, dietary supplements, and natural colorants. Structural and regulatory genes are involved in anthocyanin biosynthesis of rice. Various molecular biology techniques have been applied to improve productivity, nutritional contents, and market value of pigmented rice. This review focused on the genetics, biochemistry and biophysical analysis of anthocyanin in rice that will facilitate rice breeding program to develop new high-yield pigmented rice varieties.
