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.
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
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 ...
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.
PAST includes functions for data management, data visualisation through graphics, univariate and multivariate analysis procedures as well as linear and non-linear modelling. There are also functions for diversity calculation, time series analysis, geostatistical and stratigraphic analysis. [3] The operation is basically mouse-controlled.
Effective microorganisms enhance the soil's beneficial microbial community, paving the way for sustainable agriculture. These microorganisms consist of naturally occurring microbes, such as photosynthesizing bacteria, lactic acid bacteria, yeasts, and fermenting fungi, which can be applied to increase soil microbial diversity.
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 ...
Microbial phylogenetics is the study of the manner in which various groups of microorganisms are genetically related. This helps to trace their evolution . [ 1 ] [ 2 ] To study these relationships biologists rely on comparative genomics , as physiology and comparative anatomy are not possible methods.
