"The Rime of the Ancient Mariner"belongs to the second group. Some critics blame Coleridge for his lack of morals in this poem, but in fact,this poem contains lots of morals, as Coleridge himself said.Coleridge succeeds in exploring the theme of sin and punishment by his rich imagination and by the depicting of supernatural things. In "The Rime of the Ancient Mariner", Coleridge intentionally built a symbolic world of the supernatural wind, the bird, the sun, the moon ,the ship and the sea. All these symbols serve to develop the theme of Fall and Redemption, and play so important a part in the poem that we even can take it as a symbolic poem. In the following pages, I am going to devote to the functions of the supernatural wind in particular. Coleridge bestows the wind with a great deal of展开更多

The Himar1 (mariner) transposon is ideal for generating near-saturating mutant libraries, especially in AT-rich chromosomes, as the requirement for integration is a TA dinucleotide, and this transposon has been used for mutagenesis of a wide variety of bacteria. However, plasmids for mariner delivery do not necessarily work well in all bacteria. In particular, there are limited tools for functional genomic analysis of Pasteurellaceae species of major veterinary importance, such as swine and cattle pathogens, Actinobacillus pleuropneumoniae and Pasteurella multocida, respectively. Here, we developed plasmids, pTsodCPC9 and pTlacPC9 (differing only in the promoter driving expression of the transposase gene), that allow delivery of mariner into both these pathogens, but which should also be applicable to a wider range of bacteria. Using the pTlacPC9 vector, we have generated, for the first time, saturating mariner mutant libraries in both A. pleuropneumoniae and P. multocida that showed a near random distribution of insertions around the respective chromosomes as detected by TraDIS. A preliminary screen of 5000 mutants each identified 8 and 14 genes, respectively, that are required for growth under anaerobic conditions. Future high-throughput screening of the generated libraries will facilitate identification of mutants required for growth under different conditions, including in vivo, highlighting key virulence factors and pathways that can be exploited for development of novel therapeutics and vaccines.展开更多
