Abstract：
:An arbitrary-primed RNA PCR differential display strategy was used to identify midgut genes of the reduviid bug Triatoma infestans that were differentially expressed after a blood meal. From interesting bands, 33 distinct cDNAs were cloned and sequenced. Although many had long open reading frames, most of the transcripts were unrelated to any other sequences in any databases. Only 14 Triatoma sequences had strong homologies to those from other organisms, including genes encoding for 2-oxoglutarate dehydrogenase, CAD protein, NADH-ubiquinone-oxoreductase, epidermal growth factor, plectin, aminopeptidase, heat-shock-related 70-kDa protein, golgin, mitochondrial carrier protein and high-density lipoprotein. RT-PCR was used to demonstrate constitutive expression in four of five of these sequences. Northern hybridisation was difficult due to the very low expression levels of most of the genes. However, a gene-fragment highly homologous to a heat-shock-related 70-kDa protein was strongly expressed in starved bugs, down-regulated after feeding and again expressed later, suggesting a role for a heat-shock protein in starvation survival.
