ARAGORN, a program to detect tRNA genes and tmRNA genes in nucleotide sequences [PDF]

open access: yes, 2004
A computer program, ARAGORN, identifies tRNA and tmRNA genes. The program employs heuristic algorithms to predict tRNA secondary structure, based on homology with recognized tRNA consensus sequences and ability to form a base-paired cloverleaf.

Gene Location and Bacterial Sequence Divergence [PDF]

open access: yesMolecular Biology and Evolution, 2002
Previous comparison of a relatively small set of homologous genes from Escherichia coli and Salmonella typhimurium revealed that genes nearer to the origin of replication had substitution rates lower than genes closer to the replication terminus. The recently completed sequences of numerous bacterial genomes have allowed us to test whether this effect ...

Small variable segments constitute a major type of diversity of bacterial genomes at the species level [PDF]

open access: yes, 2010
Analysis of large scale diversity in bacterial genomes has mainly focused on elements such as pathogenicity islands, or more generally, genomic islands. These comprise numerous genes and confer important phenotypes, which are present or absent depending ...

Bacterial Genes Outnumber Archaeal Genes in Eukaryotic Genomes [PDF]

open access: yesGenome Biology and Evolution, 2019
Abstract Eukaryotes are typically depicted as descendants of archaea, but their genomes are evolutionary chimeras with genes stemming from archaea and bacteria. Which prokaryotic heritage predominates? Here, we have clustered 19,050,992 protein sequences from 5,443 bacteria and 212 archaea with 3,420,731 protein sequences from 150 ...

Mechanism and Breeding Application of Bacterial Blight Gene in Rice

open access: yesGuangdong nongye kexue, 2022
Rice is one of the most important food crops in the world. Rice disease is a major threat to its yield loss. Bacterial blight caused by the gram-negative bacterium Xanthomonas oryzae pv.

The Composition and Spatial Patterns of Bacterial Virulence Factors and Antibiotic Resistance Genes in 19 Wastewater Treatment Plants.

open access: yesPLoS ONE, 2016
Bacterial pathogenicity and antibiotic resistance are of concern for environmental safety and public health. Accumulating evidence suggests that wastewater treatment plants (WWTPs) are as an important sink and source of pathogens and antibiotic ...

Are alkane hydroxylase genes (alkB) relevant to assess petroleum bioremediation processes in chronically polluted coastal sediments? [PDF]

open access: yes, 2011
The diversity of alkB-related alkane hydroxylase sequences and the relationship between alkB gene expres- sion and the hydrocarbon contamination level have been investigated in the chronically polluted Etang-de-Berre sediments. For this purpose, these

Denitrification: from genes to ecosystems [PDF]

open access: yes, 2010
Denitrification is a part of the global nitrogen cycle in which fixed nitrogen in the biosphere is returned to the atmosphere, which is mediated by diverse communities of microorganisms. This thesis seeks to gain a greater understanding of the ecology of
