Molecular organization of great millet (Sorghum vulgare) DNA

Approximately 52% of the nuclear genome of great millet(Sorghum vulgare) consists of repetitive DNA which can be grouped into very fast, fast and slow components. The reiteration frequencies of the fast and slow reassociating components are {dy7000} and 92 respectively. Approximately 90% of the genome consists of repeated sequences interspersed amongst themselves and with single copy sequences. The interspersed repeat sequences are of three sizesviz. > 1·5 kilobase pairs, 0·5–1·0 kilobase pairs and 0·15–0·30 kilobase pairs while the size of the single copy sequences is 3·0 kilobase pairs. Hence the genome organization of great millet is essentially of a mixed type NCL communication No. 3527.
