Water stress influences the transmission of an insect-vectored plant pathogen by altering the induction of plant gene transcripts involved in defense.

Hydrocarbon input in Antarctic soils may result from anthropogenic and natural sources. In this case, a careful investigation was performed to evaluate Antarctic soil microorganisms’ genetic potential for hydrocarbon degradation.

Early season soil microbiome can accurately predict wheat grain quality at harvest.

Different dietary fructoselysine exposure affected bacterial composition as well as its metabolic capacity of infant gut microbiota.

Bacterial diversity assessed across four DWDSs: Proportion of Proteobacteria higher in non-disinfected than in disinfected systems; Sphingomonas, Mycobacterium, Lactobacillus, and Ralstonia could have an effect on promoting the formation of DBPs; Bacterial diversity in a post-treated and disinfected DWDS higher than in raw water.

Our study examines how lab strains of a widespread insect pest species (the African Armyworm) have a distinct gut microbiome and the role that gut microbes play in affecting resistance to nucleopolyhedrovirus, SpexNPV. Through a combination of antiobiotic control and field-collected frass innoculations, we demonstrate that inoculation of the field microbiome of this pest species into lab strains increases resistance to the virus, and that this is subsequently reversed when treated with a broad spectrum antibiotic.

Impacts of an invasive filter-feeder on bacterial biodiversity are context dependent.

Marine bacteria cultivable on plates are dominated by a minor population of planktonic bacteria that lives preferentially close to or on phytoplankton and particles.

DNA metabarcoding revealed a resident gut microbiota within the eastern mud snail, a keystone deposit-feeder along the US Atlantic coast, and demonstrated significant alteration of sediment bacterial assemblages following gut passage.

Controlling Heterosigma akashiwo bloom with a Streptomyces-derived algicide avoided the enrichment of nitrite, bio-laible DOM, and pathogenic bacteria by optimizing inorganic nutrient composition, enhancing DOM recalcitrance and restoring metabolic generalists.

Iron-bearing minerals are a key control on the composition of microbial communities in basaltic subglacial sediments, likely because of their ability to serve as electron acceptors in energy metabolism.
