“…All control organic horizons had a similar phyla structure, consisting predominantly of Pseudomonadota, Actinobacteriota, Acidobacteriota, Verrucomicrobiota, Planctomycetota, Bacteroidota, and Chloroflexota. A plot of old-growth spruce forest in semi-hydromorphic landscapes in the Komi Republic was characterized by similar species abundance and complexity of the microbiome structure in accordance with [89] (in particular, representatives of the phyla Actinobacteriota, Acidobacteriota, Verrucomicrobiota, and Chloroflexota). Significant changes between different organic control horizons across major phyla were shown only for Bacillota, which predominated in the Oa,pyr horizon (Figure S3).…”

Data on the main properties of Histic Podzols in the pine forests of semi-hydromorphic landscapes in the middle taiga of the Komi Republic after forest fires are presented. A decrease in topsoil horizon thickness by more than 7.6 times, an increase in litter density by 6 times, and a decrease in litter stock by 4 times were observed in postfire soil. There was an increase in carbon content in the pyrogenic horizon (48%) and in the upper part of the podzolic horizon—from 0.49 at the control plot to 1.16% after the fire. The accumulation of all studied trace metals (Cu—from 2.5 to 6.8 mg × kg−1; Zn—from 35.7 to 127.4 mg × kg−1; Ni—from 2.2 to 8.1 mg × kg−1; Pb—from 1.4 to 28.3 mg × kg−1; Cd—from 0.3 to 1.1 mg × kg−1) in soils after wildfires was recorded. The effect of the fire can be traced to a depth of approximately 20–30 cm. A significant influence of the pyrogenic factor on the alpha and beta bacterial diversity was noted. The bacterial response to a forest fire can be divided into an increased proportion of spore-forming and Gram-negative species with complex metabolism as well.

Pseudostellaria heterophylla of the Caryophyllaceae family is an important medicinal herb in traditional Chinese medicine, but it encounters continuous cropping obstacle during cultivation. This study aimed to study the differences in the response of Pseudostellaria heterophylla cultivation to soil microorganisms and phenolic substances in different types of soil (Loamy soil and Clayey soil). The analysis of soil metabolites using HPLC-ESI-Q/TOF-MS and HPLC-DAD techniques revealed that the content of various phenolic components in the rhizosphere soil increased significantly after Pseudostellaria heterophylla cultivation. Pseudostellaria heterophylla cultivation in yellow soil could increase the abundance of Proteobacteria, Ascomycota, and Thermoplasmatota, while in brown soil, the abundance of Ascomycota significantly decreased. In addition, Pseudostellaria heterophylla cultivation could increase the α-diversity of bacteria and fungi in yellow soil, while reducing the α-diversity of archaea, and the impact on diversity in brown soil was relatively small. Correlation analysis showed that phenolic compounds were more likely to regulate the genera Bradyrhizobium, Calcarisporiella, Boothiomyces and Methanocella. Pseudostellaria heterophylla may regulate rhizosphere microbial diversity and community structure by secreting phenolic. However, in different types of soil environments, the response mechanism of soil microorganisms to Pseudostellaria heterophylla planting might vary. Our study provides new insights that the variability in the response of different soil types to Pseudostelariae heterophylla cultivation should be taken into account when developing strategies for reducing continuous cropping obstacles in medicinal plants.
