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.

Klebsiella Phage ΦK64-1 Encodes Multiple Depolymerases for Multiple Host Capsular Types.

TL;DR: Nine functional capsule depolymerase-encoding genes in a bacteriophage are identified and correlated activities of the gene products to all ten hosts of this phage, providing an example of carriage of multiple depolymersases in a phage with a wide capsular type host spectrum.

The rubber tree genome shows expansion of gene family associated with rubber biosynthesis

TL;DR: The data suggest that H. brasiliensis’s capacity to produce high levels of latex can be attributed to the expansion of rubber biosynthesis-related genes in its genome and the high expression of these genes in latex.

Characterization of two polyvalent phages infecting Enterobacteriaceae.

TL;DR: Two novel virulent phages are isolated and characterized using a strain of Shigella flexneri as host bacterium and it is suggested that they may be useful for controlling bacterial populations.
