Genome-wide analysis of genes associated with moderate and high DDT resistance in Drosophila melanogaster.
BACKGROUND Moderate to high DDT resistance in generally associated with overexpression of multiple genes and therefore has been considered to be polygenic. However, very little information is available about the molecular mechanisms that insect populations employ when evolving increased levels of resistance. The presence of common regulatory motifs among resistance-associated genes may help to ...
متن کاملInsights into DDT Resistance from the Drosophila melanogaster Genetic Reference Panel
Insecticide resistance is considered a classic model of microevolution, where a strong selective agent is applied to a large natural population, resulting in a change in frequency of alleles that confer resistance. While many insecticide resistance variants have been characterized at the gene level, they are typically single genes of large effect identified in highly resistant pest species. In ...
متن کاملMalathion Resistance in Drosophila melanogaster (Diptera: Drosophilidae)
Malathion resistance developed in a Drosophila melanogaster population that has been exposed to malathion for almost 20 years. Genetic analyses showed that malathion resistance in this population is under control of several genes that are located on the first, second and third chromosome. The second chromosome contributes the most to resistance; the factor(s) involved may be (partly) dominant o...
متن کاملOlfactory Proxy Detection of Dietary Antioxidants in Drosophila
BACKGROUND Dietary antioxidants play an important role in preventing oxidative stress. Whether animals in search of food or brood sites are able to judge the antioxidant content, and if so actively seek out resources with enriched antioxidant content, remains unclear. RESULTS We show here that the vinegar fly Drosophila melanogaster detects the presence of hydroxycinnamic acids (HCAs)-potent ...
متن کاملChromosomal Analyses of the Genetic Factors for Resistance to Ddt in Two Resistant Lines of Drosophila Melanogaster.
melanogaster all pointed to the conclusion that resistance was inherited not a3 a single gene but as a polygenic complex. Numerous resistant lines had been produced by selection. In some the mean tolerance had been increased more than twentyfold. But response to selection was always slow and it was as rapid at a relatively low level of selective intensity when only the most susceptible half of ...
