The identification of molecular markers linked to leaf curl virus (CLCuV) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. Genetic analysis suggested that CLCuV resistance is controlled by a single dominant gene. In this study, an interspecific F2 population derived from a cross of Gossypium barbadense and G...
The goal of the current study was to assess possibility interspecific hybridization for transfer jassid-resistant genes from two wild cotton species Gossypium armourianum (Kearney (2n=2x=26) D2A) and Gossypium gossypoides (Standley (2n=2x= 26) D6) into genotypes cultivated hirsutum. demonstrated that seeds were successfully produced crosses between G. hirsutum armourianum using t...
The cotton (Gossypium spp.) fiber is a unique elongated cell that is useful for investigating cell differentiation. Previous studies have demonstrated the importance of factors such as sugar metabolism, the cytoskeleton, and hormones, which are commonly known to be involved in plant cell development, while the secondary metabolites have been less regarded. By mining public data and comparing an...
A successful cross fertilization involving two different species implies that a chain of reproductive process takes place unhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent and matching gene or gene complexes in the pistil parent should be hormonious. Understanding of pollen tube growth and pollen attrition is revealed from the st...
The red leaf coloration of Empire Red Leaf Cotton (ERLC) (Gossypium hirsutum L.), resulted from anthocyanin accumulation in light, is a well known dominant agricultural trait. However, the underpin molecular mechanism remains elusive. To explore this, we compared the molecular biological basis of anthocyanin accumulation in both ERLC and the green leaf cotton variety CCRI 24 (Gossypium hirsutum...
Green cotton (Gossypium hirsutum L.) fibers were shown by electron microscopy to have numerous thin concentric rings around the lumen of the cell. These rings possessed a lamellar fine structure characteristic of suberin. LiA1D(4) depolymerization and gas chromatography-mass spectrometry analysis showed the presence of a suberin polymer in the green cotton with the major aliphatic monomers bein...
Transposable elements (TEs) are a major component of plant genomes. It is of particular interest to explore the potential activation of TE proliferation, especially in hybrids and polyploids, which often are associated with rapid genomic and epigenetic restructuring. Here we explore the consequences of genomic merger and doubling on copia and gypsy-like Gorge3 long terminal repeat (LTR) retrotr...
Cotton (Gossypium spp.) is an economically important crop that is grown throughout the world. It is the main material in textile and the main economic resource for more than 100 millions of cotton farmers in China. Due to its main role in our economy, cotton biotechnology has been significantly improved in the last decades in China, which led to a significantly progress both in cotton research ...
Fluorescence in situ hybridization on extended DNA (fiber-FISH) is a powerful tool in high-resolution physical mapping. To introduce this technique into cotton, we developed the technique and tested it by deliberately mapping of telomere and 5S rDNA. Results showed that telomere-length ranged from 0.80 kb to 37.86 kb in three species, G. hirsutum, G. herbaceum and G. arboreum. However, most of ...
