Analysis of repetitive DNA in three species of Gossypium

Biochemical Genetics, 1976
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.

Molecular phylogeny of Gossypium species by DNA fingerprinting

Theoretical and Applied Genetics, 2000
Total genomic DNA from 31 available Gossypium species, three subspecies and one interspecific hybrid, were analysed to evaluate genetic diversity by RAPD, using 45 random decamer primers. A total of 579 amplified bands were observed, with 12.9 bands per primer, of which 99.8% were polymorphic.

Molecular confirmation of species status for the allopolyploid cotton species, Gossypium ekmanianum Wittmack

Genetic Resources and Crop Evolution, 2014
Understanding the relationship between domesticated crop species and their wild relatives is paramount to germplasm maintenance and the utilization of wild relatives in breeding programs. Recently, Gossypium ekmanianum was resurrected as an independent species based on morphological analysis of specimens obtained from the Dominican Republic, where the ...

Micropropagation of Cotton (Gossypium Species)

1992
Cotton belongs to the genus Gossypium, family Malvaceae. This genus comprises 39 species (Fryxell 1984), which have been categorized into seven genome groups based on the cytology of interspecific hybrids (Beasley 1942; Phillips and Strickland 1966; Edwards and Mirza 1979).

THE CYTOLOGY AND PHYLOGENETICS OF THE DIPLOID SPECIES OF GOSSYPIUM

American Journal of Botany, 1966
Meiotic chromosome behavior of 11 inter‐genomic hybrids of Gossypium (2n = 26) were investigated. Per cell univalent frequencies at meiotic metaphase I in these hybrids were: A genome × Cgenome—G. herbaceum × sturtianum, 10.53; G. herbaceum × australe, 18.05. A genome × E genome—G. smnalense × arboreum, 21.82. B genome × C genome—G.

A comparison of chemical properties of seeds of Gossypium species

Economic Botany, 1960
The possibility of utilizing gene pools from wild cottons in the improvement of commercial varieties, with special reference to seed quality, has led to the quanititative analysis of seeds from several species of Gossypiumun. The prinmary purpose of the study was to suipply data for Gossypiumt species that may serve to aid.

Meiosis of a Triple Species Hybrid in Gossypium

Nature, 1944
SKOVSTED1,2 brought forward considerable cytological evidence that New World (n = 26) cottons originated by amphidiploidy from crosses between ancestral Asiatic (n = 13) and American (n = 13) parents. Recently Harland3 and Beasley4 have independently synthesized by colchicine treatment amphidiploids from hybrids between present-day Asiatic and American

The occurrence of (+) gossypol inGossypium species

Journal of the American Oil Chemists' Society, 1971
Abstract(+) Gossypol, 2,2′‐bi[8‐formyl‐1,6,7‐trihydroxy‐5‐isopropyl‐3‐methylnaphthyl], has been isolated as the (+) dianilino derivative from cottonseed grown in widely different areas of the cottonbelt of the United States. The optically active derivative obtained had rotations varying from 43% to 54.7% of the value reported for the optically pure ...

Cross-species transferability of G. arboreum-derived EST-SSRs in the diploid species of Gossypium

Theoretical and Applied Genetics, 2006
Diploid species with a common Gossypium origin are highly diverse in morphology and have been classified into eight genomic groups designated A-G and K. In this study, the transferability of 207 Gossypium arboreum-derived expressed sequence tag-simple sequence repeat (EST-SSR) primer pairs was examined among 25 different diploid accessions representing
