  • Title: [Molecular structure of plant genomes].
    Author: Sivolap IuM, D'iachenko LF, Novoselov AN.
    Journal: Mol Biol (Mosk); 1977; 11(4):877-82. PubMed ID: 618330.
    Abstract:
    The genome structure of several species of Graminea and Drosophila was investigated by DNA renaturation method. Kinetics of DNA reassociation was studied by direct optical scanning and the data obout Cot curve were analized by an improved computer programm "Finger". Differences between structure DNA animals and plants are shown. Plant genomes have no unique fraction which exists in animal genomes. Slowly reassociating fraction in plants comprises about 20% DNA as compared with more than 60% in animal DNA. An analysis of kinetic complexity indicates that the relative content of the slowly reassociating fraction in the genome both of animal and of plants is much higher than that of the highly repeated DNA fraction.
