Increasing tolerance to Cry1Ac cotton from cotton bollworm, Helicoverpa armigera
1. Changes in the frequency of Cry1Ac resistance genes and shifts in tolerance of cotton bollworm, Helicoverpa armigera , to the Cry1Ac toxin were assessed using bioassays of F 1 and F 2 offspring of isofemale lines from Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) and Xiajin County of Shandong Province (an intensive Bt cotton planting ar...
متن کاملDynamic transcriptome analysis and volatile profiling of Gossypium hirsutum in response to the cotton bollworm Helicoverpa armigera
In response to insect herbivory, plants emit elevated levels of volatile organic compounds for direct and indirect resistance. However, little is known about the molecular and genomic basis of defense response that insect herbivory trigger in cotton plants and how defense mechanisms are orchestrated in the context of other biological processes. Here we monitored the transcriptome changes and vo...
متن کاملAgrobacterium-mediated Transformation of Cotton (Gossypium hirsutum) Using a Synthetic cry1Ab Gene for Enhanced Resistance Against Heliothis armigera
Cotton (Gossypium hirsutum L.) is an important fiber crop in Iran, cultivated on 150000-200000 ha of land. In Iran the estimated loss due to the insect pest is more than 30%. Traditionally, pests are controlled by 10-12 times spraying per growing season of environmentally harmful chemical insecticides (e.g. endosulfan and/or methosystox). In order to produce transgenic cotton resistance to in...
متن کاملConstruction of Genetic Linkage Map and QTL Analysis for Fiber Traits in Diploid Cotton (Gossypium arboreum x Gossypium herbaceum)
Diploid A genome cottons are grown for their natural fiber in drought prone areas of Asia. Although they possess inferior fiber qualities to cultivated Upland and Pima cotton, their value lies in their inherent resistance to pests and diseases. Molecular linkage maps provide essential tools for plant genetic research, facilitating quantitative trait locus (QTL) mapping, marker-assisted selectio...
متن کاملResistance allele frequency to bt cotton in field populations of helicoverpa armigera (Lepidoptera: Noctuidae) in China.
Resistance evolution in target insects to Bacillus thurningiensis (Bt) cotton, Gossypium hirsutum L., is a main threat to Bt cotton technology. An increasing trend of population density of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) has been observed since 2001 in Qiuxian County (Hebei, China), where Bt cotton has been planted dominantly since 1998. This region was selected in 2006 a...
