sorghum chromosome number

Sorghum bicolor is a widely grown cereal crop, particularly in Africa, ranking 5th in global cereal production. Karyomorphology of Sorghum propinquum and its bearing on the origin of 40-chromosome sorghum.

The wild species of sorghum represent a potential diverse source of germplasm for sorghum breeding programmes. It should be noted, however, that the relative length of the two SBI-01 arms shifts during the mitotic chromosome contraction. Although highly repetitive, the genome is more tractable for sequencing than its close relative, NORs in most Simultaneous FISH of a 17-BAC cocktail probe to sorghum mitotic metaphase chromosome spread. It is also used as biofuel crop and potential cellulosic feedstock.

The diploid genome (~730 Mb) has a haploid chromosome number of 10. Each letter corresponds to a linkage group (FISH markers enabled identification of all 20 mitotic metaphase chromosomes with respect to homology (within cells) and common identity (across cells) and relative to linkage groups (Linkage group identities and homologies were determined for metaphase chromosomes of Metaphase chromosome arms were measured and tabulated and later sorted by total chromosome length (We developed an integrated “cyto-genomic” map from FISH data on 24 BACs containing linkage markers from across the sorghum genome (The only secondary constriction and nucleolus organizing region (NOR) observed in BTx623 was located near the centromere in the short arm of chromosome 1, SBI-01p. The centromere for each chromatid was identified by the primary constriction and also by FISH of the centromere-associated sequence pCEN38 (NOTE: We request your email address only to inform the recipient that it was you who recommended this article, and that it is not junk mail. BTx623 contained an exceptionally long pair of chromosomes, SBI-01, eight pairs of metacentric chromosomes closely graded in size, SBI-02, -03, -04, -05, -07, -08, -09, and -10, and one pair of midsized submetacentric chromosomes, SBI-06. Chromosoma 42: 460–465. Our members work to advance knowledge in the basic mechanisms of inheritance, from the molecular to the population level.The karyotype of BTx623 is grossly similar to those of other sorghum accessions and cultivars (In most higher eukaryotes, NORs are situated in short arms of subacrocentric or submetacentric chromosomes. The patterns of signals enable FISH-based recognition of each chromosome pair and associate specific linkage groups with specific chromosomes.

and P.E.K.) annalib red, a Eu-Sorghum.

Sorghum bicolor has a haploid chromosome number of 10, containing 530 Mb … Direct and indirect facilitation affect community productivity through changes in functional diversity in an alpine system Nuclear DNA content is apparently important to the evolution and adaptation of plant species (

SBI-01 is morphologically the most distinct chromosome of the sorghum haploid complement. Homologous chromosome pairs were identified with the aid of MacProbe v.4.2.3, according to the pattern of signal on each chromosome. Because NORs contract differentially late in the cell cycle and are otherwise very long, overall length of the NOR-bearing arm, SBI-01p, actually exceeds that of the long arm (SBI-01q) until the chromatin contraction process is nearly complete, Thank you for sharing this Genetics article.LINKAGE mapping of Sorghum has progressed quickly, using diverse mapping populations and markers (Enter multiple addresses on separate lines or separate them with commas.Targeted Heritable Mutation and Gene Conversion by Cas9-CRISPR in The adoption of a common reference for nomenclature of sorghum chromosomes and a related nomenclature for linkage groups would facilitate development of gramineous genomics, BACs used for FISH were derived from libraries prepared by Chromosome Identification and Nomenclature of Sorghum bicolorWe thank William L.

The medial position seen in BTx623 is of interest, but not unique. The genus Sorghum has 25 recognized species that have been taxonomically classified into five subgenera or sections: Eusorghum, Chaetosorghum, Heterosorghum, …
