Nuclear volume, chromosome size and DNA content relationships in three species of Pinus.

New report on chromosome number , karyotype and 4 C DNA content in three species of

Extensive karyotype analysis including determination of somatic chromosome number, total chromosome length and volume and estimation of 4C DNA content were carried out on three species of Pachypodium namely P. lamerei; P. namaquanum and p rosulatum ' horombense' for the first time. A significant variation in nuclear DNA amount was recorded at interspecific level. The somatic chromosome number 2...

Nuclear DNA content variation and species relationships in the genus Lupinus (Fabaceae).

The 2C nuclear DNA content has been estimated by flow cytometry in 18 species and botanical forms of the genus Lupinus (family Fabaceae), using propidium iodide as a fluorescent dye. They represented distinct infrageneric taxonomic groups and differed in somatic chromosome numbers. Estimated 2C DNA values ranged from 0.97 pg in L. princei to 2.44 pg in L. luteus, which gives a more than 2.5-fol...

Nuclear DNA content and genome size of trout and human.

NUCLEAR DNA CONTENT AND GENOME SIZE OF TROUT AND HUMAN In their recent paper, Thomas et al. (1) discussed design, resolution, sensitivity, and reproducibility of the National Aeronautics and Space Administration/American Cancer Society flow cytometer. The results of their study demonstrated high stability and sensitivity of the instrument, which is suitable for detection of near-diploid tumor c...

karyological and nuclear dna content variation in some iranian endemic thymus species (lamiaceae)

thymus is a medicinal plant which contains one of the world's top ten essential oils, exhibiting antibacterial, antioxidative, food preservative and mammalian age-delaying properties. this work was aimed at identifying between-species variations requiring for selecting appropriate parents for hybridization. six iranian endemic thymus accessions belonging to thymus daënensis, t. eriocalyx and t....
