This species is the oldest of the listed and characterized by long and almost transparent grains. ⦠All the BPH-resistance genes identified to date have been from indica rice or wild species. Rice is often characterized as one of three varieties - long grain, medium grain, or short grain rice. The japonica cultivars thus met the cereal Cd limits of China (0.2 mg kg-1) under low and moderate soil Cd pollution. Indica rice usually accumulates more Cd in shoots and grains than Japonica rice. Rice varieties are often classified as so-called Indica, Japonica and Javanica groups on the basis of morphological variations. Here, we provide a comprehensive characterization of transcriptome The Cd content of the indica cultivar grain was 1.84-4.14 times higher than that of the japonica cultivars (P < 0.05). and . The F\1\ hybrids between varieties belonging to the latter two types, however, have normal F\1\ fertility (Morinaga 1958). Japonica rice is also stickier due to the higher content of amylopectin, whereas indica rice starch consists of less amylopectin and more amylose. The percentage of indica varieties m⦠In Japan, generally, rice should be consumed in 2 months in winter, 1 month in spring/fall, and 2 weeks in summer. In addition, this species grains are very hard, so the process of cleaning the rice ⦠It ⦠Japonica . We mapped NPQ regulator and identified a locus (qNPQ1-2) that seems to be responsible for the difference in NPQ capacity between Indica and Japonica. Subpopulation differences are well known in , especially between subspecies . Japonica Japonica varieties are usually cultivated in dry fields (it is cultivated mainly submerged in Japan), in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while indica varieties are mainly lowland rices, grown mostly submerged, throughout tropical Asia. Cd translocation from sheath to grain occurred along with sugar transfer in the indica cultivars. In a previous study, a collection of 533 different cultivated rice accessions was divided into , indica. I wonder whatâs the difference between Japanese rice and korean rice. It is found in the cooler zones of the subtropics and in the temperate zones. These results suggest a high level of genetic differentiation between indica and japonica rice. However, the proteins and genes responsible for these differences remain poorly ⦠It is a group of rice varieties from northern and eastern China grown extensively in some areas of the world. japonica/indica hybrid rice was higher than that of japonica rice by 75.6% at N0, 57.2% at N150, 41.1% at N225, 38.3% at N300, and 45.8% at N375. Organic matter content ranged from 8.92 g/Kg to 17.98 g/Kg, and the OM, TP, and AP contents were not significantly different among all the compared groups. Across the four rice varieties, N uptake increased significantly with increased N-fertilizer rates at all the growth stages (p < 0.05). However, underlying genetic bases for differential Cd accumulation between Indica and Japonica rice are still unknown. However, the differences between these subspecies at the transcriptome level remains largely unexamined. Theor Appl Genet 104:1â8. The main difference between japonica and indica is that japonica grain is roundish, short, do not shatter easily and have 10-24% amylose whereas indica grain is slender, somewhat flat, long to short, and have 23-31% amylose. Many studies have shown genotypic differences in Cadmium (Cd) accumulation among rice cultivars, and concentrations in shoots and grains are generally higher in indica rice cultivars than in japonica rice cultivars, but the mechanism remains unknown. and . Compare to japonica, indica rice has been less responsive to in vitro culture. The effect of soluble starch synthase I (SSI) on differences of amylopectin structure between the indica and japonica rice varieties was investigated. Japonica varieties, on the other hand, are grown in both tropical and temperate environments, and only account for approximately 20% of rice ⦠Both basmati and jasmine rice belong to Indica species. Across the three planting years, the average grain yield of japonica/indica hybrid rice was higher than that of japonica rice by 75.6% at N0, 57.2% at N150, 41.1% at N225, 38.3% at N300, and 45.8% at ⦠Cultivated rice consists of two subspecies: Indica and Japonica. According to a 2004 study (Zhu et al. A recombinant inbred line (RIL) population of F 8 and F 9 generations derived from a cross between a typical indica rice (Qishanzhan) and a typical japonica rice (Akihikari) was used to study the difference between morphological differentiation based on phenotype characters and genetic differentiation using indica and japonica ⦠To prove that the 1 bp Indel is specific for salt tolerance between indica and japonica rice varieties, we investigated the genotype of this 1 bp Indel in 66 diverse rice accessions based on the data of pan-genome analysis (Zhao et al. Japonica rice grains are also harder than those of Indica rice. RN, RL, and MRL had differences at the significant level of p < 0.05 in the two subpopulations, while the difference of RGA between the two subpopulations ⦠In this study, we cloned a quantitative trait locus ⦠Japonica is a group of rice varieties from northern and eastern China grown extensively in some areas of the world.

Meanwhile, the genetic diversity of the landraces was higher than that of the improved varieties, and Na of the improved varieties was 86.5% of the landraces. The differences in quality traits between indica and japonica. Using an F(2) population from a cross between the indica cultivar 93-11 and B14, we mapped the BPH12 gene to a 1.9-cM region on ⦠65 No. These two rice varieties are the complete opposites of each other. 2012). For the relationship between GY and PN (GY-PN), a negative association was found for the II (r = -0.17, P < 0.001) and IH (r = -0.32, P < 0.001), but a positive association was found for the JI (r = 0.27, P < 0.001) and JH (r = 0.33, P < 0.001; Figure 2A). Relationship between grain yield and quality in rice Breeding Science Vol. Japonica Rice. These results indicate the presence of rich genomic diversity at the SNP level among the 353 accessions. Generally, japonica rice varieties are more tolerant to low temperatures than varieties of indica rice. There were clear, significant differences between japonica rice and indica rice soils at each soil layers. -quality traits also showed distinct Eating distributions within subpopulations (Figure 1B). Recent genetic evidence show that all forms of Asian rice, both indica and japonica, come from a single domestication event that occurred 8,200â13,500 years ago in the Pearl River valley region of China. Rice can be divided into several species. Indica and japonica are two main subspecies of Asian cultivated rice (Oryza sativa L.) that differ clearly in morphological and agronomic traits, in physiological and biochemical characteristics and in their genomic structure. We used Illumina Hiseq 2000 sequencing platform for comparative transcriptome analysis between two rice subspecies at six different ⦠There was an obvious difference in SSR allelic diversity between indica and japonica rice.

In the present study, transcriptomic analysis was performed to illustrate the different reactions of Indica and Japonica rice to Al toxicity. In 1980s, the hybrid sterility between Indica and Japonica types was analyzed, and Indica, Japonica, and wide-compatibility type which gives fertile hybrids when cross to Indica and Japonica types, are proved to contain an allele, S 5 i, S 5 j and S 5 n, respectively at a locus on chromosome 6. ABSTRACT. Long Grain Rice- This rice has milled grains that are at least three to four times as long as they are wide. Japonica rice plants are shorter than indica rice plants. 1. Japonica cultivars generally showed higher NPQ capacities than Indica cultivars when we measured a rice core collection. They are usually available in late fall and winter. Right after Japonica comes the second major Asian rice variety, Indica rice. In the past 15 years, grain quality in japonica rice and indica hybrid rice have improved, while there have been limited improvements in indica inbred riceâthe head rice rate has increased, but the chalky rice rate and amylose content have decreased. Generally, japonica rice has a significantly higher head rice rate, lower degree of chalkiness, lower amylose content, and higher gel consistency than indica rice; all these characteristics of japonica contribute to ⦠Due to its starch composition, it is sepa⦠While Japonica rice features round and thick grains, the Indica rice has longer and thinner grains. 1. japonica (Huang et al.

We also found that as compared with japonica rice, the Japonica is one of the two major eco-geographical races of O. sativa (O. sativa japonica), the other is Indica. The Food War between Rice. The most popular are Indica, Javanica and Japonica. Indica varieties are cultivated throughout the tropics, and account for the majority of rice production worldwide. The BPH12 gene in the indica rice accession B14 is derived from the wild species Oryza latifolia. Indica rice showed more variation than japonica rice both for Na and He. Somatic embryogenesis is a unique process in plants and has considerable interest for biotechnological application. Simply speaking, long grain rice will have a longer cylindrical shape, whereas short grain rice will be shorter and wider. Japonica rice grains are rounder, thicker, and harder, compared to longer, thinner, and fluffier indica rice grains. China is a major rice-producing country and is acutely aware of the importance of improving the quality and yield of rice. Although japonica rice and indica rice are the main food in China, peopleâs evaluation of them has changed several times in the past decades. Rice is a major source of cadmium (Cd) intake for Asian people. in rice breeding, if the mechanism of Al-tolerance between Indica and Japonica could be proven to be different. Therefore, cold tolerance in indica rice can be improved by introducing genes from japonica rice through molecular breeding. 2004), the brown rice ratios of japonica and indica in China were 83.6% and 80.5%, respectively, while the head rice ratios of japonica and indica were 67.8% and 49.4%, respectively.
