PICRUSt [1] is a bioinformatics software package. The name is an abbreviation for Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.. The tool serves in the field of metagenomic analysis where it allows inference of the functional profile of a microbial community based on marker gene survey along one or more samples.
Metatranscriptomics is the set of techniques used to study gene expression of microbes within natural environments, i.e., the metatranscriptome. [1]While metagenomics focuses on studying the genomic content and on identifying which microbes are present within a community, metatranscriptomics can be used to study the diversity of the active genes within such community, to quantify their ...
UniFrac, a shortened version of unique fraction metric, is a distance metric used for comparing biological communities.It differs from dissimilarity measures such as Bray-Curtis dissimilarity in that it incorporates information on the relative relatedness of community members by incorporating phylogenetic distances between observed organisms in the computation.
Metagenomic approaches to the analysis of complex microbial communities allow the targeted screening of enzymes with industrial applications in biofuel production, such as glycoside hydrolases. [84] Furthermore, knowledge of how these microbial communities function is required to control them, and metagenomics is a key tool in their understanding.
T-RFLP Analysis (APLAUS+): Another ‚‘in-silico‘‘ assignment tool on the website of the Microbial Community Analysis project at the University of Idaho: BEsTRF: a tool for optimal resolution of terminal restriction fragment length polymorphism analysis based on user defined primer-enzyme-sequence databases
A 2015 study analyzed a panel of Arabidopsis hormone mutants impaired in synthesis or signaling of individual or combinations of plant hormones, the microbial community in the soil adjacent to the root and in bacteria living within root tissue. Changes in salicylic acid signaling stimulated a reproducible shift in the relative abundance of ...
Knowledge of the composition and metabolic activity of the microbiota in soils, water and waste materials is useful in optimizing crop production, in bioremediation and in understanding microbial ecosystems. Soil microbial community analysis by PLFA has been a widely used technique due to the sensitive, reproducible measurement of the dominant ...
the ability to perform genomic and gene expression analyses of single cells and of entire microbial communities in the disciplines of metagenomics and metatranscriptomics [13] databases accessible to researchers across multiple disciplines [13] methods of mathematical analysis suitable for complex data sets [13]
