Identification of differential expression genes associated with host selection and adaptation between two sibling insect species by transcriptional profile analysis.

ABSTRACT:

Background

Cotton bollworm (Helicoverpa armigera) and oriental tobacco budworm (Helicoverpa assulta) are noctuid sibling species. Under artificial manipulation, they can mate and produce fertile offspring. As serious agricultural insect pests, cotton bollworms are euryphagous insects, but oriental tobacco budworms are oligophagous insects. To identify the differentially expressed genes that affect host recognition and host adaptation between the two species, we constructed digital gene expression tag profiles for four developmental stages of the two species. High-throughput sequencing results indicated that we have got more than 23 million 17nt clean tags from both species, respectively. The number of unique clean tags was nearly same in both species (approximately 357,000).
