Cotton (Gossypium hirsutum L.r. latifolium Hutch) is very sensitive to soil conditions. The Iuiu Valley, located in the Southwest of Bahia State in Brazil, was an important area for cotton production but an inadequate soil management for years and consequent soil quality degradation lead to the decline of the crop in the region. In an effort to reestablish cotton, this study was carried out to ...

A bacterial artificial chromosome (BAC) library for the A-genome of cotton has been constructed from the leaves of G. arboreum L cv. Jianglinzhongmian. It is used as elite A-genome germplasm resources in the present cotton breeding program and has been used to build a genetic reference map of cotton. The BAC library consists of 123,648 clones stored in 322 384-well plates. Statistical analysis ...

Cotton (Gossypium spp.) belonging to the genus Gossypium in the family Malvaceae. Cotton is an important fibre crop of global importance. It is grown in tropical and subtropical regions of more than 80 countries with an annual production of 20 million tonnes. It is an important source of oil and high quality protein meal and plays a significant role in the national economy. Among the cotton pro...

An increasing area of transgenic Bacillus thuringiensis (Bt) cotton is being planted in saline-alkaline soil in China. The Bt protein level in transgenic cotton plants and its control efficiency can be affected by abiotic stress, including high temperature, water deficiency and other factors. However, how soil salinity affects the expression of Bt protein, thus influencing the control efficienc...

BACKGROUND Upland cotton, Gossypium hirsutum L., is one of the world's most important economic crops. In the absence of the entire genomic sequence, a large number of expressed sequence tag (EST) resources of upland cotton have been generated and used in several studies. However, information about the flower development of this species is rare. METHODOLOGY/PRINCIPAL FINDINGS To clarify the mo...

Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...

Effective use of Gossypium hirsutum L. lines in cotton genetic improvement programs depends on the extent of genetic variation for desirable alleles and the accurate characterization of the variability among germplasm accessions. Marker assisted selection has provided the potential for efficient development of disease and pest resistant plants. Association mapping is used to identify chromosoma...

Cotton is one of the most economically important fiber crop plants worldwide. The genus Gossypium contains a single allotetraploid group (AD) and eight diploid genome groups (A-G and K). However, the evolution of repeat sequences in the chloroplast genomes and the phylogenetic relationships of Gossypium species are unclear. Thus, we determined the variations in the repeat sequences and the evol...
