A program is described, tRNAscan-SE, which identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases.
Abstract
We describe a program, tRNAscan-SE, which identifies 99-100% of transfer RNA genes in DNA sequence while giving less than one false positive per 15 gigabases. Two previously described tRNA detection programs are used as fast, first-pass prefilters to identify candidate tRNAs, which are then analyzed by a highly selective tRNA covariance model. This work represents a practical application of RNA covariance models, which are general, probabilistic secondary structure profiles based on stochastic context-free grammars. tRNAscan-SE searches at approximately 30 000 bp/s. Additional extensions to tRNAscan-SE detect unusual tRNA homologues such as selenocysteine tRNAs, tRNA-derived repetitive elements and tRNA pseudogenes.

Distinctive Genome Reduction Rates Revealed by Genomic Analyses of Two Coxiella-Like Endosymbionts in Ticks

TL;DR: The CRt genome is an extreme example of a symbiont genome caught in the act of genome reduction, and the comparison between CLEAA and CRt indicates that losses of particular genes early on in this process can potentially greatly influence the speed of this process.

Comparative and functional genomics of Rhodococcus opacus PD630 for biofuels development.

TL;DR: In this paper, a comparative analysis of the 9.27 Mb R. opacus PD630 genome was performed and the results of the catabolic screen, phylogenetic analysis of TAGs cycle enzymes, and metabolic product characterizations were integrated into a working model of prokaryotic oleaginy.

Structural Analysis of a Lotus japonicus Genome. V. Sequence Features and Mapping of Sixty-four TAC Clones Which Cover the 6.4 Mb Regions of the Genome

TL;DR: A total of 56 TAC clones with an average insert size of 100 kb were isolated from a TAC library of the Lotus japonicus genome based on the expressed sequences tags, cDNA and gene information, and their nucleotide sequences were determined according to the shot-gun based strategy.

Complete mitochondrial DNA sequence of Tigriopus japonicus (Crustacea: Copepoda).

TL;DR: The complete nucleotide sequence of the mitochondrial genome was determined for a harpacticoid copepod, Tigriopus japonicus (Crustacea), using an approach that employs a long polymerase chain reaction technique and primer walking, resulting in one of the smallest mitochondrial genomes in the arthropod lineage.
