Adjacent-1 duplication-deficiencies (dp-dfs) are readily recovered from most heterozygous translocations in Gossypium hirsutum L., but frequencies of specific cytotypes differ widely in progenies from heterozygote (female symbol) x standard crosses. Surprisingly, these frequencies seem to be unrelated to the primary (postmeiotic) frequencies predicted by metaphase I configurations or to the pro...

Similar Cry proteins are expressed in both Bt corn, Zea mays L., and cotton, Gossypium hirsutum (L.), commercial production systems. At least one generation of corn earworm, Helicoverpa zea (Boddie), completes development on field corn in the Mid-South before dispersing across the landscape into other crop hosts like cotton. A concern is that Bt corn hybrids may result in selection for H. zea p...

Methyl jasmonate (MeJA)-mediated defense in conventional cotton, Gossypium hirsutum L. (Malvaceae), against cotton bollworm, Helicoverpa armigera (H€ ubner) (Lepidoptera: Noctuidae), was investigated with respect to the activities of the detoxification enzymes acetylcholinesterase (AChE), carboxylesterase (CarE), and glutathione S-transferases (GST) in pupae as well as the performance of larvae...

Abstract Background Soil salt stress seriously restricts the yield and quality of cotton worldwide. To investigate molecular mechanism response to stress, a main cultivated variety Gossypium hirsutum L. acc. Xinluzhong 54 was used perform transcriptome proteome integrated analysis. Results Through analysis in leaves under for 0 h (T0), 3 (T3) 12 (T12), we identified 8 436, 11 628 6 311 differen...

Background: Gossypium arboreum is resistant to Cotton leaf curl Burewala virus and its cognate Cotton leaf curl Multan betasatellite (CLCuBuV and CLCuMB). However, the G. arboreum wax deficient mutant (GaWM3) is susceptible to CLCuV. Therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission a...

Potassium uptake rate of two cotton (Gossypium hirsutum L.) varieties viz., NIBGE-2 and MNH-786 was investigated in nutrient solution culture having deficient K @ 0.3 mM and deficient K+ Na @ 0.3 +2.7 mM. Depletion of K from solution was monitored over a period of 24 h at regular time intervals after 0, 0.5, 1.0, 1.5, 2, 3, 4, 5, 6, 8, 10, 12 and 24 h to estimate K uptake kinetics of the roots ...

In this study, six taxa of micromycetous fungi collected from Golestan province (N Iran) during spring and summer of 2010, are reported. Melanospora zobelii on Picoa lefebvrei, Diachea leucopodia on Sambucus nigra, Choanephora cucurbitarum on Brassica oleracea, Trichurus spiralis on Prunus domestica, tuber of Solanum tuberosum and seeds of Gossypium hirsutum and Dictyosporium heptasporum on dea...

There is much interest in the role that agricultural practices might play in sequestering carbon to help offset rising atmospheric CO₂ concentrations. However, limited information exists regarding the potential for increased carbon sequestration of different management strategies. The objective of this study was to quantify and contrast carbon dioxide exchange in traditional non-mulching with f...

The tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is one of the most important pests of cotton, Gossypium hirsutum L, that has become resistant to a wide range of synthetic insecticides. CrylAc-expressing cotton has proven its effectiveness against this insect since its introduction in North America in 1996. However, the constant exposure of tobacco budworm to this protein...

Aphids cause significant damage to crop plants. Studies regarding predator-prey relationships in fennel (Foeniculum vulgare Mill.) and cotton (Gossypium hirsutum L.) crops are important for understanding essential ecological interactions in the context of intercropping and for establishing pest management programs for aphids. This study evaluated the association among Hyadaphis foeniculi (Passe...
