Two systemic neonicotinoids, imidacloprid and thiamethoxam, are widely used for residual control of several insect pests in cotton (Gossypium spp.), vegetables, and citrus (Citrus spp.). We evaluated their impact on six species of beneficial arthropods, including four parasitoid species--Aphytis melinus Debach, Gonatocerus ashmeadi Girault, Eretmocerus eremicus Rose & Zolnerowich, and Encarsia ...

This study investigates the inhibitory activities of gossypol, a natural polyphenolic compound from Gossypium spp., against Helicobacter pylori (HP) clinical strains and urease enzyme that plays key role in pathogenesis HP. Gossypol was detected to exhibit bacteriostatic action all HP tested with minimum concentration (MIC) values ranging 3.51 4.14 µg/mL. The activity (HPU) efficiently impeded ...

Modern cotton (Gossypium spp. L) cultivars are efficient in nutrient uptake and utilization, thus, may potentially tolerate stress. Early- late-season stress (E-stress L-stress, respectively) effects on productivity quality were assessed under different production conditions Camilla Midville, GA, USA. The E-stress received no application the early season, but full rates split-applied equally at...

Vigna unguiculata, Cassia fasiculata, and Sesamum indicum did not support Meloidogyne arenaria, M. incognita, or Heterodera glycines race 4 in greenhouse studies with soils from peanut and soybean fields. Fagopyron eseulentum, Cyamopsis tetragonoloba, and Cucurbita pepo were hosts to the two Meloidogyne spp. but were nonhosts to H. glycines. Meloidogyne arenaria and M. incognita galled but repr...

Genetic mapping studies have suggested that diploid cotton (Gossypium) might be an ancient polyploid. However, further evidence is lacking due to the complexity of the genome and the lack of sequence resources. Here, we used the grape (Vitis vinifera) genome as an out-group in two different approaches to further explore evidence regarding ancient genome duplication (WGD) event(s) in the diploid...

PREMISE OF THE STUDY Single-nucleotide polymorphism (SNP) marker discovery in plants with complex allotetraploid genomes is often confounded by the presence of homeologous loci (along with paralogous and orthologous loci). Here we present a strategy to filter for SNPs representing orthologous loci. METHODS AND RESULTS Using Illumina next-generation sequencing, 54 million reads were collected ...

Scientific information on the A genome species of Gossypium is limited due to their decline as crop species and low levels of marker polymorphism. As the A subgenome of the allotetraploid species of Gossypium is contributed by A genome progenitors, studies on the A genome will help us understand the evolution of polyploids. We compared DNA marker order along the chromosomes of A, D and At genom...

In order to determine the effects of different water-saving irrigation techniques on physiological growth, farmland microclimate, and yield cotton (Gossypium Spp.), a two-year field experiment was carried out in an oasis area Northwest China, three methods were tested, including on-film (T1), under-film drip (T2), automatic (T3). The results showed that relative humidity, plant height, leaf are...

In this study, two halophilic bacterial strains isolated from saline habitats in Argentina grew in the presence of gas oil. They were identified as Halomonas spp. and Nesterenkonia sp. by 16S ribosomal RNA sequencing. Chemotaxis towards gas oil was observed in Halomonas spp. by using swimming assays.
