finger millet chromosome number
%PDF-1.5 Introduction Finger millet [Eleusine coracana (L.) Gaertn] is a potential future crop because of its adaptabil-ity to environmental fluctuations and high nutritional value. | Finger millet was native and first domesticated in The finger millet—rice comparative maps demonstrated that other than the rearrangements that are necessary to account for the difference in the chromosome number between finger millet and rice, the finger millet genome has remained highly conserved since its divergence from a common ancestor with rice some 60 million years ago. Abstract Eleusine (Poaceae) includes six diploid and three polyploid species and has three basic chromosome numbers, x=8, 9 and 10. Finger millet, Eleusine coracana L., is also known as African millet, koracan, ragi (India). among these crops.9 Comparative maps of finger millet and rice demonstrated that other than the rearrangements that are necessary to account for the difference in the chromosome number between these 2 genomes, the finger millet genome has remained highly conserved as its divergence from a com- It is believed that Ethiopia or a neighboring region (Uganda) is the center of origin of finger millet, but in India, it was introduced probably over 3000 yr ago. belongs to family Poaceae commonly known as ragi, mandua, nagli, kapai and madua is widely cultivated in India. It has a 2530 Mb genome size and a diploid chromosome number of 7, 2n = 14 (Bennett et al., 2000). It is relatively resistant to water logging and has few serious diseases. 2018 Feb 1;25(1):39-47. doi: 10.1093/dnares/dsx036.

Eleusine tristachya was included since it is the only other annual diploid species in the genus with a basic chromosome number of x = 9 like finger millet. Multiple hybrid de novo genome assembly of finger millet, an orphan allotetraploid crop. Eleusine coracana, commonly called finger millet, is an important cereal of semi-arid regions, cultivated in parts of Africa and India for its grain. Pearl millet (family: Poaceae, subfamily: Panicoideae) is a multi-purpose cereal crop which provides food, fodder and fuel on more than 27 million hectares worldwide (Jalaja et al., 2016). Finger millet is mostly self-pollinating, with some amount of cross-pollination (1%) mediated by wind (Jansen and Ong 1996; Purseglove 1972). The QTL for neck blast was associated with the genomic SSR marker UGEP18 which was linked at a P value of 0.01 and explained 11% of phenotypic variance. Niacin is important to maintaining the health of your skin, blood, and organs. Before sowing secondary tillage with cultivator and multiple tooth hoe to prepare smooth seed bed is necessary. Finger millet is one of the important minor millets grown in the world providing highly nutritious grains which are high in protein, fats and minerals as compared to other popular crops like rice and sorghum (Barbeau and Hilu 1993). <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 594.96 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> COVID-19 is an emerging, rapidly evolving situation.
