Twenty bacterial artificial chromosome (BAC) clones that could produce bright signals and no or very low fluorescence in situ hybridization (FISH) background were identified from Gossypium arboreum cv. JLZM, and G. hirsutum accession (acc.) TM-1 and 0-613-2R. Combining with 45S and 5S rDNA, a 22-probe cocktail that could identify all 13 G. arboreum chromosomes simultaneously was developed. According to their homology with tetraploid cotton, the G. arboreum chromosomes were designated as A1-A13, and a standard karyotype analysis of G. arboreum was presented. These results demonstrated an application for multiple BAC-FISH in cotton cytogenetic studies and a technique to overcome the problem of simultaneous chromosome recognition in mitotic cotton cells.

“…A total of 111 loci detected with these 99 EST-SSRs integrated with 511 SSR loci and two morphological marker loci assorted to 34 linkage groups containing 2 to 41 markers each, covering 5644.3 cm with an average intermarker distance of 9.0 cm. Intraspecific genetic linkage map of the Agenome diploid cotton was constructed with newly developed SSR markers using 189 F2 plants derived from the cross of two Asiatic cotton cultivars (G. arboreum L.) 'Jianglingzhongmian × Zhejiangxiaoshanl'ushu (Ma et al, 2008). For this study, 268 pairs of SSR primer with better polymorphism were picked out of 6092 pairs which generated a total of 320 polymorphic bands.…”

The genus Gossypium has 45-50 species, of which only four (two allotetraploids and two diploids) enjoy the status of cultivated cotton. Among the four cultivated ones, Gossypium arboreum holds a special place because of the inherent ability to withstand drought, salinity and remarkable resistance to sucking pests and leaf curl virus. However, the species suffer with poor fiber quality traits, low yield and has certain undesirable plant and boll features. Improvement of fiber quality traits of G. arboreum, without disturbing its unique characteristics, has been a long sought after dream of scientists world over. For conservation, evaluation and documentation of existing accessions, gene banks of diploid cultivated cotton has been established by different countries, of which India holds the highest number of G. arboreum collections. Traditional breeding efforts made to improve fiber quality of G. arboreum have met with limited success due to paucity of polymorphic phenotypic markers and polygenic nature of the desired traits. Genetic engineering approach is highly genotype dependent and much success has not been achieved by this way also. Molecular breeding approach, based on the strength of breeding with high polymorphic nature of molecular markers, has yielded significant results in the improvement of G. arboreum. A number of molecular markers have been developed and used in various cotton improvement programs but dominantly these efforts have been made for the allotetraploid species G. hirsutum. Some efforts have been made for generating fingerprint database of G. arboreum germplasm, though much more efforts are needed in this direction. Linkage maps of G. arboreum have been generated using different markers systems which has enabled the mapping of gene/QTLs of desired traits on the chromosome of G. arboreum. More research inputs need to be devoted to produce consensus and saturated genomic maps, if the aim of 'breeding by design', by retaining suitable features and improving the undesirable ones, is to be realized for G. arboreum.

“…Cotton (Gossypium spp) is one of the most expansively grown species around the globe, and is grown in tropical and subtropical regions between the latitudes 36°S and 46°N (Reller and Gerstenberg, 1997) in more than 80 countries (Fryxell, 1979;Smith, 1995). The Gossypium genus consists of 50 species (Fryxell, 1992;Stewart, 1995;Ma et al, 2008), which includes five allotetraploid species [2n = 4x = 52; (AD) 1 to (AD) 5 ] and 45 diploid species (2n = 2x = 26, A through G and K) (Fryxell, 1979;Stewart, 1995;Brubaker et al, 1999;Zhang et al, 2005). The evolution of domesticated cotton has involved various steps, which provide scientists with insight into the role of polyploidy in the diversification process and permit the investigation of unique traits.…”

ABSTRACT. Gossypium tomentosum and G. darwinii are wild allotetraploid cotton species, characterized by many excellent traits, including fiber fineness, drought tolerance, and Fusarium and Verticillium wilt resistance. Based on the construction of F 2 linkage groups of G. hirsutum x G. tomentosum and G. hirsutum x G. darwinii, two genetic linkage maps were compared. As a result, we found a total of seven inverted fragments on chr02, chr05, chr08, chr12, chr14, chr16, and chr25, and three translocated fragments on chr05, chr14, and chr26. In addition, comparison of the inverted and translocated fragments revealed that the orientation of four of seven markers in G. tomentosum were consistent with G. hirsutum or G. raimondii. The orientation of one of seven inverted markers of G. darwinii was consistent with G. hirsutum, and the orientation of one of three translocated markers of G. tomentosum was consistent with G. raimondii. These results indicate that, in comparison to G. darwinii, G. tomentosum has a closer genetic relationship to G. hirsutum. These findings will be important for our understanding on the genome structure of G. tomentosum and G. darwinii, and set the scene for further in-depth genome research such as fine mapping, tagging genes of interest from wild relatives, and evolutionary study.
