Phylogenetic and functional characterization of the hAT transposon superfamily.
Transposons are found in virtually all organisms and play fundamental roles in genome evolution. They can also acquire new functions in the host organism and some have been developed as incisive genetic tools for transformation and mutagenesis. The hAT transposon superfamily contains members from the plant and animal kingdoms, some of which are active when introduced into new host organisms. We...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
Characterization of a small mobilizable transposon, MTnSag1, in Streptococcus agalactiae.
The transposon MTnSag1 from Streptococcus agalactiae carried an IS1-like transposase gene and the lnu(C) gene, which encoded a lincosamide nucleotidyltransferase. MTnSag1 could be mobilized by the conjugative transposon Tn916. An intermediate circular form of MTnSag1 and a putative origin of transfer at the 3' end of the lnu(C) gene were characterized.
متن کاملTransposon Mutagenesis in Bifidobacterium breve: Construction and Characterization of a Tn5 Transposon Mutant Library for Bifidobacterium breve UCC2003
Bifidobacteria are claimed to contribute positively to human health through a range of beneficial or probiotic activities, including amelioration of gastrointestinal and metabolic disorders, and therefore this particular group of gastrointestinal commensals has enjoyed increasing industrial and scientific attention in recent years. However, the molecular mechanisms underlying these probiotic me...
متن کاملmPing: The bursting transposon
Though transposable elements (TEs) have been considered as an efficient source of evolution, it has never been possible to test this hypothesis because most of TE insertions had occurred millions of years ago, or because currently active TEs have very few copies in a host genome. However, mPing, the first active DNA transposon in rice, was revealed to hold a key to answer this question. mPing h...
