Contribution of mobile genetic elements on variation in gene content among bacteria
نویسندگان
چکیده
Bacterial genomes vary widely in gene content [1]. This variation can be the result of different evolutionary events including gene loss, gene duplication, and horizontal gene transfer [2]. Mobile genetic elements such as plasmids and viruses are major vehicles to transfer genes between different cells, and thus play a key role in the evolution and diversification of bacteria [3]. To understand the importance of the mobile genetic elements in bacterial evolution, we investigated contributions of plasmids and viruses on variation in gene content among bacteria.

Prevalence of Class 1 Integron in Klebsiella Pneumoniae Isolates from Hospitals of Sanandaj, Iran
Background and Aims: Integrons as mobile genetic elements are located on the chromosome or on a plasmid in bacteria. Integrons play a main role in the dissemination of antibiotic resistance genes among different families of bacteria. The aim of this study was to identify the prevalence of class 1 integron in Klebsiella pneumoniae isolates from hospitals of Sanandaj, Kurdistan province, Iran. M...

SeqWord Gene Island Sniffer, a new program for the identification of mobile genetic elements in sequences of bacterial chromosomes is presented. This program is based on the analysis of oligonucleotide usage variations in DNA sequences. 3,518 mobile genetic elements were identified in 637 bacterial genomes and further analyzed by sequence similarity and the functionality of encoded proteins. Th...
متن کاملP30: Are There Anxious Genes?
Anxiety comprises many clinical descriptions and phenotypes. A genetic predisposition to anxiety is undoubted; however, the nature and extent of that contribution is still unclear. Extensive genetic studies of the serotonin (5-hydroxytryptamine, 5-HT) transporter (5-HTT) gene have revealed how variation in gene expression can be correlated with anxiety phenotypes. Complete genome-wide linkage s...

Tomato yellow leaf curl virus (TYLCV) is a supreme pathogen in tropical and subtropical areas. During 2014-2015, a total of 393 tomato samples showing Tomato yellow leaf curl disease (TYLCD) symptoms were collected from six different provinces of Iraq. In serological assays, 55 out of 393 samples (14%) reacted positively with TYLCV-specific antibodies .The presence of TYLCV was verified in 21 (...

Background: Extended spectrum beta lactamases (ESBLs) are an important cause of transferable multidrug resistance (MDR) in gram-negative bacteria. The most described ESBL genes are generally found within integron-like structures as mobile genetic elements. The aim of this study was to identify the accompanying of class 1 integrons and ESBLs in the MDR E. coli isolates. Methods: Susceptibility t...
