The effects of two entomopathogenic fungal endophytes, Beauveria bassiana and Purpureocillium lilacinum (formerly Paecilomyces lilacinus), were assessed on the reproduction of cotton aphid, Aphis gossypii Glover (Homoptera:Aphididae), through in planta feeding trials. In replicate greenhouse and field trials, cotton plants (Gossypium hirsutum) were inoculated as seed treatments with two concent...

Transgenic cotton (Gossypium hirsutum L.) with Bacillus thuringiensis Berliner δ-endotoxin genes has been widely adopted for suppression of lepidopteran pests. To account for inconsistency of the endotoxin gene expression, we developed a polymerase chain reaction (PCR) for checking the purity of transgenic cotton plants. A total of eight cry1Ac genes were aligned for the PCR primer design. A DN...

Cotton rats (Sigmodon hispidus) replicate measles virus (MV) after intranasal infection in the respiratory tract and lymphoid tissue. We have cloned the cotton rat signaling lymphocytic activation molecule (CD150, SLAM) in order to investigate its role as a potential receptor for MV. Cotton rat CD150 displays 58% and 78% amino acid homology with human and mouse CD150, respectively. By staining ...

Bt-transgenic cotton has proven to be highly efficient in controlling key lepidopteran pests. One concern with the deployment of Bt cotton varieties is the potential proliferation of non-target pests. We previously showed that Bt cotton contained lower concentrations of insecticidal terpenoids as a result of reduced caterpillar damage, which benefited the aphid Aphis gossypii. It is thus import...

Damage to cotton by micro-organisms causes a serious loss to the cotton farmer, manufacturer, and consumer. For this reason studies are in progress in the Department of Agriculture on the growth and effect of various micro-organisms which cause deterioration of cotton. In an earlier investigation in this laboratory by Rogers, Wheeler, and Humfeld (1940) the growth of Chaetomium globosum Kunze o...

Crop rotation has been practiced for centuries in an effort to improve agricultural yield. However, the directions, magnitudes, and mechanisms of the yield effects of various crop rotations remain poorly understood in many systems. In order to better understand how crop rotation influences cotton yield, we used hierarchical Bayesian models to analyze a large ecoinformatics database consisting o...

in order to evaluate the yield and nitrogen use efficiency of corn and cotton intercropping under different levels of nitrogen, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were nitrogen fertilizers in four levels (0, 50, 100 and 150 kg ha-1) and planting pattern in three levels (maize sol...

Cotton is the most important crop for the production of fiber that plays a key role in economic and social affairs. The aim of the study was to evaluate the impact of biofield energy treatment on cotton seeds regarding its growth, germination of seedling, glutathione (GSH) concentration, indole acetic acid (IAA) content and DNA fingerprinting using simple sequence repeat (SSR) markers for polym...

The recently stated hypothesis that histamine liberation by cotton dust extracts is caused by endotoxins from gram-negative bacteria contained in cotton was studied experimentally in various animals. It was shown clearly that such amounts of endotoxin as were found in cotton dust did not give rise to histamine liberation which was provoked by extracts from cotton card-room dusts. Further argume...

In the 21st century, advent of the omics era provides scientists with greater opportunities to dissect molecular mechanisms of cotton fiber development. Cotton contributes natural fiber for the worldwide textile industry; therefore, dissecting its biological properties is a very important scientific objective. Current Chinese scientists have made significant contributions to cotton omics, focus...
