chromosome number of sorghum

7 de janeiro de 2021

Rice chromosomes 5 and 10 as well as sorghum chromosomes 1 and 9 were substantially enriched for putative orthologs and outnumbered the remaining chromosomes of the respective genomes. The chromosome number for E. esculenta appears to be variable, from 2n = 36, 42, 48, 54 to 2n = 72 (CCDB, undated), but cultivated strains are hexaploid (Aoki and Yamaguchi, 2008). Enter multiple addresses on separate lines or separate them with commas. Populations from the USA and Canada are of Mediterranean origin and are a tetraploid ecotype. The NOR of its close rhizomatous relative, S. propinquum, is located in the short arm of the smallest chromosome (Magoon and Shambulingappa 1961). Although C-banding can be used for identification of sorghum chromosomes that are not fully condensed (Yu et al. 2. in which chromosome number is built by units of ten (i.e. The diploid races originated in south Eurasia.

Sorghum bicolor is a widely grown cereal crop, particularly in Africa, ranking 5th in global cereal production. 1984).
