The emergence and fate of horizontally acquired genes in Escherichia coli

, 2008
Bacterial species, and even strains within species, can vary greatly in their gene contents and metabolic capabilities. We examine the evolution of this diversity by assessing the distribution and ancestry of each gene in 13 sequenced isolates of ...

Structure and Function of Soil Bacterial Communities in the Different Wetland Types of the Liaohe Estuary Wetland

Microorganisms
Soil bacterial communities play a crucial role in the functioning of estuarine wetlands. Investigating the structure and function of these communities across various wetland types, along with the key factors influencing them, is essential for ...

Anaerobic methane-oxidizing bacterial communities in sediments of a drinking reservoir, Beijing, China

Annals of Microbiology, 2020
Purpose Nitrate/nitrite-dependent anaerobic methane oxidation (N-DAMO) connects the global cycle of carbon and nitrogen in aquatic ecosystems. The aims of this study were to investigate the spatiotemporal variation of N-DAMO bacteria and its driving ...

Diversity of Bacterial Biosynthetic Genes in Maritime Antarctica

Microorganisms, 2020
Bacterial natural products (NPs) are still a major source of new drug leads. Polyketides (PKs) and non-ribosomal peptides (NRP) are two pharmaceutically important families of NPs and recent studies have revealed Antarctica to harbor endemic polyketide ...

Phage Resistance Reduced the Pathogenicity of Xanthomonas oryzae pv. oryzae on Rice

Viruses, 2022
Plants grow together with microbes that have both negative and positive impacts on the host, while prokaryotes are in turn also hosts for viruses, co-evolving together in a complex interrelationship.

What traits are carried on mobile genetic elements, and why? [PDF]

, 2010
Although similar to any other organism, prokaryotes can transfer genes vertically from mother cell to daughter cell, they can also exchange certain genes horizontally.

Effect of bacterial inoculation, plant genotype and developmental stage on root-associated and endophytic bacterial communities in potato (Solanum tuberosum)

, 2010
Beneficial bacteria interact with plants by colonizing the rhizosphere and roots followed by further spread through the inner tissues, resulting in endophytic colonization.

Synthesis of empty bacterial microcompartments, directed organelle protein incorporation, and evidence of filament-associated organelle movement [PDF]

, 2010
Compartmentalization is an important process, since it allows the segregation of metabolic activities and, in the era of synthetic biology, represents an important tool by which defined microenvironments can be created for specific metabolic functions ...

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

, 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.

Dna Supercoiling and Bacterial Gene Expression [PDF]

Science Progress, 2006
DNA in bacterial cells is maintained in a negatively supercoiled state. This contributes to the organization of the bacterial nucleoid and also influences the global gene expression pattern in the cell through modulatory effects on transcription.
