Genes Translocated into the Plastid Inverted Repeat Show Decelerated Substitution Rates and Elevated GC Content
Plant chloroplast genomes (plastomes) are characterized by an inverted repeat (IR) region and two larger single copy (SC) regions. Patterns of molecular evolution in the IR and SC regions differ, most notably by a reduced rate of nucleotide substitution in the IR compared to the SC region. In addition, the organization and structure of plastomes is fluid, and rearrangements through time have re...
متن کاملIdentified Hybrid tRNA Structure Genes in Archaeal Genome
Background: In Archaea, previous studies have revealed the presence of multiple intron-containing tRNAs and split tRNAs. The full unexpurgated analysis of archaeal tRNA genes remains a challenging task in the field of bioinformatics, because of the presence of various types of hidden tRNA genes in archaea. Here, we suggested a computational method that searched for widely separ...
متن کاملLateral transfer and GC content of bacterial resistance genes
Lateral genetic transfer (LGT) is one of the ways in which microorganisms such as bacteria could move and rearrange genetic materials from and into their genomes (Ragan and Beiko, 2009). The dissemination of antibiotic resistance genes between two microorganisms or between a microorganism and the environment could occur, for example, by conjugation, transduction, and transformation (Fondi and F...
متن کاملDetection of tRNA Genes with Introns from DNA Sequences of Archaea
With the progress of genome projects, a vast amount of nucleotide sequence data is now available, which makes it possible to study the species-specific gene expression systems involving transcription and translation for a wide range of organisms. To understand species-specific translation system, it is important for comprehending the whole set of tRNAs for individual species. We have been devel...
متن کاملGC content provides new insights into exon recognition
Studies throughout the years revealed several characteristics that differentiate alternative exons from constitutive ones. However, some of those characteristics, such as splice signals and other regulatory sequences, are inherently sequence-based. Herein we show that these characteristics are heavily biased by GC content, and may not actually differ between alternative and constitutive exons. ...
