Features of the Formation of Microbiomes in Two Types of Soils under Pine Provenance Trials of Pinus sibirica Du Tour and Pinus koraiensis Siebold et Zucc

The effect of pine provenance trials of Pinus sibirica Du Tour and Pinus koraiensis Siebold et Zucc. grown in Krasnoyarsk and Khabarovsk krais on the chemical and biological parameters of gray forest and brown forest soils in the rhizosphere and between rows of plantations is compared. It is shown that the interspecies heterogeneity of pines affects the chemical composition of the soil, the enzymatic and microbiological activity, and the formation of prokaryotic microbiomes. It is noted that the biodiversity of prokaryotes is more strongly determined by the features of soil types than by the inter- and intraspecies heterogeneity of pines and by the effect of their roots. The phyla Proteobacteria, Acidobacteria, and Actinobacteria dominate in both soil types and together account for 75-85% of the total number of type-specific 16S rRNA gene sequences in each soil.
