Despite its use, the long life cycle of Nipponbare makes it time-consuming for most genetic analyses. In short, we wanted to 1) confirm the genetic bottleneck in African rice as a result of domestication; 2) identify which alleles have been driven to (near) fixation as a result of artificial selection; 3) discover population … New Insights Into the Nature of Interspecific Hybrid Sterility in Rice. multiregional) domestication origin for African rice.

Identification of the domestication center of O. glaberrima . Oryza glaberrima is the African cultivated rice species, domesticated from its wild ancestor by farmers living in Inland Delta of Niger River. Mussurova S, Al-Bader N, Zuccolo A, Wing RA. Portères, R. in Origins of African Plant Domestication (ed. 2008;174:394–408. Sequence comparisons of OsSh1 and Sh4 . Background African rice, Oryza glaberrima , is an invaluable resource for rice cultivation and for the improvement of biotic and abiotic resistance properties. cultivars with improved yield and quality traits, that have been adopted Figure 2. 1957). eCollection 2020. Figure 4. glaberrima, thus we hypothesize that Trinidad rice has a higher proportion of the Oryza glaberrima genome. It incorporates the previously assembled chromosome 3 short arm (Chr3s) sequence and consists of 12 chromosome pseudomolecules and 1,939 unplaced scaffolds. Here we present a high-quality assembly and annotation of the O. glaberrima genome and detailed analyses of its evolutionary history of domestication and selection. Variation effect prediction with sequence ontology. Oryza glaberrima is one of the two cultivated species of rice, and harbors various interesting agronomic traits, especially in biotic and abiotic resistance, compared with its Asian cousin O. sativa. O. glaberrima is a west African species of cultivated rice that was domesticated independently of Asian rice (O. sativa ssp. ; yellow, gene and repeat density between red and blue); and D paralogous relationships between, Plot of the composite likelihood ratio (CLR) across. Since its domestication in the inner Niger delta ca. Figure 4. Population genomics analyses of 20 O. glaberrima and 94 Oryza barthii accessions support the hypothesis that O. glaberrima was domesticated in a single region along the Niger river as opposed to noncentric domestication events … Genome Wide Association Study Pinpoints Key Agronomic QTLs in African Rice Oryza glaberrima. drought). There are only two species of cultivated rice in the world: Oryza glaberrima, or African rice, and Oryza sativa, or Asian rice.Native to sub-Saharan Africa, O. glaberrima is thought to have been domesticated from the wild ancestor Oryza barthii (formerly known as Oryza brevilugata) by peoples living in the floodplains at the bend of the Niger River some 2,000–3,000 years ago (1, 2). RepeatMasker with MIPS and AGI repeat libraries, and Dust, TRF. They were independently domesticated from divergent progenitor wild species in different geographic locations, South Asia and West Africa, respectively [2] . Genome sequencing and analysis of numerous wild rice (Oryza rufipogon) and Asian cultivated rice (Oryza sativa) accessions have enabled the identification of genome-wide signatures of rice domestication and the unlocking of the origin of Asian cultivated rice. African rice was independently domesticated ~3000 years ago in the Ann Bot. Data source Oryza Genome Evolution Project. The genome sequence was generated and assembled by the Arizona Genomics Institute (AGI) using strain IRGC:96717. By analyzing whole genome re-sequencing data from 282 individuals of domesticated African rice Oryza glaberrimaand its progenitor O. barthii, we hypothesize a non-centric (i.e. In 2005 the Nipponbare genome was sequenced and annotated to a high-quality level (International Rice Genome Sequencing and Sasaki 2005). [1] Distinct evolutionary patterns of Oryza glaberrima deciphered by genome sequencing and comparative analysis.Hiroaki S, Hiroshi I, Tsuyoshi T, Hisataka N, Hiroshi M, Masaki F, Michie S, Kanako K, Ari K, Masao H et al: Distinct evolutionary patterns of Oryza glaberrima deciphered by genome sequencing and comparative analysisThe Plant Journal 2011, 66(5):796-805. Generally, African rice has small, pear-shaped grain, reddish bran and green to black hulls, straight, simply-branched panicles, and short, rounded ligules. Nabholz B, Sarah G, Sabot F, Ruiz M, Adam H, Nidelet S, Ghesquière A, Santoni S, David J, Glémin S. Mol Ecol. The five wild and two domesticated A genome species, Oryza sativa and Oryza glaberrima, can be crossed relatively easily. Scipio is used for the retrieval of the genome sequence corresponding to a protein query. Figure 5. We detected evidence for artificial selection at a genome-wide scale, as well as with a set of O. glaberrima genes orthologous to O. sativa genes that are known to be associated with domestication, thus indicating convergent yet independent selection of a common set of genes during two geographically and culturally distinct domestication processes. 1.

The genome was assembled as outlined in Supplementary Figure 1and is composed of 5,309 scaffolds (scaffold N50, 217 kb) assembled into 12 pseudomolecules, result- ing in a total assembly size of 316 Mb (Supplementary Table 2). This organ is thought to aid in seed dispersal and prevent predation by animals. NIH Although less cultivated than the Asian rice (O. sativa), O. glaberrima landraces often display interesting adaptation to rustic environment (e.g. Oryza is a genus of plants in the grass family. 2020 Sep 23;11:555572. doi: 10.3389/fpls.2020.555572. eCollection 2020. 2020 Sep 16;13(1):66. doi: 10.1186/s12284-020-00424-1.

The complex history of the domestication of rice. What can I find? Interestingly, African rice is not of the same origin as Asian rice (Oryza sativa L.) but rather is an entirely different species (i.e., Oryza glaberrima Steud.). Both species have same genome AA (Chang 1976, Morinaga et al. Harlan, J.R.) 409–452 (Mouton Publishers, 1976). However, these studies could rarely identify the precise natures of specific DNA sequence changes, because it was usually not clear whether the changes occurred in the indica or japonica lineage. Epub 2014 Apr 18. African rice is a tall rice plant, usually under 120 cm but up to five meters for floating varieties, which may also branch and root from higher stem nodes.

The Oryza genus contains 11 different genome types across 27 species, both diploid and polyploid, with a 3.6-fold difference in genome sizes (from around 300 Mb in the diploid FF genome of O. brachyantha to 1,283 Mb in the HHJJ polyploid genome of O. ridleyi, with the AA genome of cultivated rice falling in the 400Mb range). The tool does not require any annotation data, and is able to correctly identify the gene even if this is spread on several genome contigs and contains mismatches and frameshifts. There are two distinct cultivated species in the genus Oryza that both belong to the AA genome with diploid level (2n = 24), O. sativa (Asian rice) and O. glaberrima (African rice).
