Creation of Cellulolytic Communities of Soil Microorganisms-A Search for Optimal Approaches.

For the targeted selection of microbial communities that provide cellulose degradation, soil samples containing cellulolytic microorganisms and specific plant residues as a substrate can be used. The details of this process have not been studied: in particular, whether the use of different soils determines the varying efficiency of communities; whether these established cellulolytic communities will have substrate specificity, and other factors. To answer these questions, four soil microbial communities with different cellulolytic activity (Podzol and the soil of Chernevaya taiga) and substrates (oat straw and hemp shives) with different levels of cellulose availability were used, followed by trained communities that were tested on botrooth substrates (in all possible combinations).

Microbial Composition on Abandoned and Reclaimed Mining Sites in the Komi Republic (North Russia).

Restoration of anthropogenically disturbed soils is an urgent problem in modern ecology and soil biology. Restoration processes in northern environments are especially important, due to the small amounts of fertile land and low levels of natural succession. We analyzed the soil microbiota, which is one of the indicators of the succession process is the soil.

Dynamic of the Soil Microbiota in Short-Term Crop Rotation.

Crop rotation is one of the oldest and most effective methods of restoring soil fertility, which declines when the same plant is grown repeatedly. One of the reasons for a reduction in fertility is the accumulation of pathogenic and unfavorable microbiota. The modern crop rotation schemes (a set of plant species and their order in the crop rotation) are highly effective but are designed without considering soil microbiota dynamics.

Diversity Indices of Plant Communities and Their Rhizosphere Microbiomes: An Attempt to Find the Connection.

The rhizosphere community represents an "ecological interface" between plant and soil, providing the plant with a number of advantages. Despite close connection and mutual influence in this system, the knowledge about the connection of plant and rhizosphere diversity is still controversial. One of the most valuable factors of this uncertainty is a rough estimation of plant diversity.

Phenome-wide functional dissection of pleiotropic effects highlights key molecular pathways for human complex traits.

Over the recent decades, genome-wide association studies (GWAS) have dramatically changed the understanding of human genetics. A recent genetic data release by UK Biobank (UKB) has allowed many researchers worldwide to have comprehensive look into the genetic architecture of thousands of human phenotypes. In this study, we used GWAS summary statistics derived from the UKB cohort to investigate functional mechanisms of pleiotropic effects across the human phenome.

Draft Genome Sequence of Sinorhizobium meliloti Strain CXM1-105.

Sinorhizobium meliloti is a Gram-negative bacterium which fixes atmospheric nitrogen in symbiosis with Medicago spp. We report the draft genome sequence of S. meliloti strain CXM1-105, associated with nodules of Medicago sativa subsp.

Draft Genome Sequence of Sinorhizobium meliloti AK555.

The inoculation of legume seeds with Sinorhizobium bacteria significantly improves pasture production. Here, we report the draft genome sequence of symbiotically efficient and salt-tolerant Sinorhizobium meliloti inoculant strain AK555, which substantially increases biomass yield of a number of Medicago sativa subsp. varia varieties, such as "Agniya," "Vega 87," and "Selena.
