Pantropic retroviral vectors mediate somatic cell transformation and expression of foreign genes in dipteran insects.

abstract：:Phenotypic diversity is frequently generated by differences in gene expression. In this study, we addressed the relationship between homology in gene expression and phenotype among four species of eusocial wasps. Specifically, we investigated the evolution of caste-specific and sex-specific gene expression patterns as...
