Analysis of repetitive DNA in three species of Gossypium
Biochemical Genetics
|December 1, 1976
Abstract:
The rate of reassociation of denatured DNA was determined for two selected diploid species, Gossypium thurberi (D genome) and G. arboreum (A genome), and one allotetraploid species, G. hirsutum (AD genome). The relative genome size and DNA content of the chromosomes of the diploids were A greater than D. Renaturation curves indicated that the differences in genome sizes were due primarily to the repetitive DNA content.
