摘要: The improved cDNA representational difference analysis was preliminarily used to analyse the genetic differences between the deltamethrin-susceptible and -resistant strain of the diamondback moth. The driver amplicon is the cDNA from the susceptible strain while the tester amplicon is from the resistant strain. After four rounds of subtractive hybridization, we obtained one different product, the size of which was about 200 bp. Comparisons between our sequencing results and data in GenBank show that there is one sequence which has a relatively high homology to the ubiquitin gene, but there are no reports indicating that its upregulated expression is correlated with insecticide resistance. Hence further studies are warranted.
