Salicylic Acid and Jasmonic Acid Signaling Defense Pathways Reduce Natural Bacterial Diversity on Arabidopsis thaliana

Molecular Plant-Microbe Interactions, 2007
Terrestrial plants serve as large and diverse habitats for a wide range of pathogenic and nonpathogenic microbes, yet these communities are not well described and little is known about the effects of plant defense on microbial communities in nature.

Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals [PDF]

, 2013
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

MICROBIAL CHARACTERIZATION OF ABANDONED MINING AREA OF SIDI KAMBER NORTH-EAST OF ALGERI [PDF]

, 2018
The ecological importance of soil bacteria is not limited to their number or biomass, although these parameters contribute greatly. Indeed, their main asset lies in their great genetic and functional diversity.

Expression of factor V by resident macrophages boosts host defense in the peritoneal cavity [PDF]

, 2019
Macrophages resident in different organs express distinct genes, but understanding how this diversity fits into tissue-specific features is limited. Here, we show that selective expression of coagulation factor V (FV) by resident peritoneal macrophages ...

High-throughput sequencing of 16S rRNA gene amplicons : effects of extraction procedure, primer length and annealing temperature [PDF]

, 2012
The analysis of 16S-rDNA sequences to assess the bacterial community composition of a sample is a widely used technique that has increased with the advent of high throughput sequencing.

Beyond one-size-fits-all approach: How do various harvesting strategies shape soil microbial diversity in Larix gmelinii (Daxinganling larch) forests of the Greater Khingan Mountains?

Frontiers in Microbiology
This study analyzed the effects of six harvesting strategies, including primary forests (PF), shelterwood cutting (SC), clear cutting (CC), optional cutting with low intensity (OCL), optional cutting with moderate intensity (OCM), and optional cutting ...

Stream microbial diversity responds to environmental changes: Review and synthesis of existing research

Frontiers in Microbiology, 2015
The importance of microbial activity to ecosystem function in aquatic ecosystems is well established, but microbial diversity has been less frequently addressed. This review and synthesis of the hundreds of published studies on stream microbial diversity

Phylogenetically diverse bacterial species produce histamine

Systematic and Applied Microbiology
Histamine is an important biogenic amine known to impact a variety of patho-physiological processes ranging from allergic reactions, gut-mediated anti-inflammatory responses, and neurotransmitter activity. Histamine is found both endogenously within specialized host cells and exogenously in microbes.
