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 ...
Approximately 185,000 Gossypium EST sequences comprising >94,800,000 nucleotides were amassed from 30 cDNA libraries constructed from a variety of tissues and organs under a range of conditions, including drought stress and pathogen challenges. These libraries were derived from allopolyploid cotton (Gossypium hirsutum; A(T) and D(T) genomes) as well as its two diploid progenitors, Gossypium arb...
BACKGROUND AND AIMS Gossypium is an economically important, globally distributed taxon comprising more than 50 species. DNA content estimates from about half of the species indicate over a 3-fold variation exists. However, the nine DNA content estimates for G. hirsutum reveal over a 2-fold difference for this species alone. Recent reports have shown that several plant compounds can bias DNA con...
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...
Several restriction sites in the cytochrome oxidase I gene of fall armyworm, Spodoptera frugiperda (J.E. Smith), were identiÞed by sequence analysis as potentially being speciÞc to one of the two host strains. Strain speciÞcity was demonstrated for populations in Florida, Texas, Mississippi, Georgia, and North Carolina, with an AciI and SacI site speciÞc to the rice (Oryza spp.)-strain and a Bs...
Understanding the composition, evolution, and function of the Gossypium hirsutum (cotton) genome is complicated by the joint presence of two genomes in its nucleus (AT and DT genomes). These two genomes were derived from progenitor A-genome and D-genome diploids involved in ancestral allopolyploidization. To better understand the allopolyploid genome, we re-sequenced the genomes of extant diplo...
Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), or fall armyworm, is an important agricultural pest of several crops in the Western Hemisphere, including cotton (Gossypium L.). Two morphologically identical host strains of fall armyworm exist that differ in plant host use and habitat distribution. The corn-strain is a primary pest of corn, Zea mays L., whereas the rice-strain is th...
