Non-human microbiome, August 14, 2014

Microbial diversity in lichen, rhizosphere microbiome, and a trip to the bottom of the “seaquence”.

Plant microbiome

Algal and Fungal Diversity in Antarctic Lichens – Chae Haeng Park – Journal of Eukaryotic Microbiology

“In the current study, we analyzed algal and lichen-associated fungal community structure in lichen species from King George Island, Antarctica by pyrosequencing of eukaryotic LSU and algal ITS domains of the nuclear rRNA gene.”

Nitrogen-transforming archaea and bacteria in tropical soils are affected under transgenic as compared to non-transgenic maize – Simone Raposo Cotta – Applied and Environmental Microbiology

“The data show that significant changes occurred in the abundances (revealed by qPCR) of ammonia-oxidizing bacterial and archaeal communities as a result of the maize host being genetically-modified.”

Soil microbiome

Spatial patterns of microbial diversity and activity in an aged creosote-contaminated site
Shinjini Mukherjee – ISME Journal

“Spatial distribution of bacterial groups unveiled patterns of niche differentiation regulated by patchy distribution of pollutants and an east-to-west pH gradient at the studied site. “

Water microbiome

Carbohydrate-active enzymes identified by metagenomic analysis of deep-sea sediment bacteria – Barbara Klippel – Extremophiles

“Metagenomic DNA purified from the pooled enrichments was sequenced and analyzed for phylogenetic composition and presence of genes encoding carbohydrate-active enzymes.”

Voyage to the bottom of the ‘seaquence’ – Rachael Wash & Carmen Diaz Soria – Nature Reviews Microbiology

“This month’s Genome Watch highlights the use of deep sequencing metagenomics to identify bacteriophages that carry sulphur-oxidizing genes in deep-sea hydrothermal vent plumes.”
