Abstract
Understanding the microbial community structure in soil contaminated with heavy metals (HMs) is a precondition to conduct bioremediation in mine soil. Samples were collected from a typical lead-zinc (Pb-Zn) mine to assess the microbial community structure of the HMs concentrated in the soil. The goal was to analyze the bacterial and fungal community structures and their interactions using the 16S rRNA genes and internal transcribed spacer high-throughput sequencing. Analyses at different sampling sites showed that contamination with HMs significantly reduced the bacterial richness and diversity but increased that of the fungi. The predominant bacteria genera of Acidobacteriales, Gaiellales, Anaerolineaceae, Sulfurifustis, and Gemmatimonadaceae, and predominant fungal genera of Sordariomycetes, Talaromyces, and Mortierella were assumed as HM resistant genera in Pb-Zn mining area. The pH effect on the bacterial and fungal communities was opposite to those of Cd, Pb, and Zn. This study offers comprehensive outlooks for bacterial and fungal community structures upon multiple HM stresses in the soil around a typical Pb-Zn mine area.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:86097-86109.

Abstract
The Ebinur Lake wetland in Xinjiang is a typical wetland, comprising a desert ecosystem with rich soil microbial resources, especially soil fungi in the inter-rhizosphere regions of the wetland plants. This study aimed to clarify the diversity and community structures of the inter-rhizosphere soil fungi of plants in areas of high salinity in the Ebinur Lake wetland and their correlations with environmental factors, as little is currently known on this topic. The diversity and differences in the community structures of fungi associated with 12 salt-tolerant plant species in the Ebinur Lake wetland were investigated using 16S rRNA sequencing. Correlations between the fungi and environmental factors, specifically, the physiochemical characteristics of the soil, were evaluated. The results showed that fungal diversity was highest in the rhizosphere soil of Haloxylon ammodendron, followed by H. strobilaceum. The dominant fungal groups were found to be Ascomycota and Basidiomycota, and the dominant genus was Fusarium. Redundancy analysis revealed significant associations between total nitrogen, electrical conductivity, and total potassium in the soil and both the diversity and abundance of the fungi (P < 0.05). Furthermore, the abundance of fungi of all genera in the rhizosphere soil samples were found to be strongly correlated with environmental physicochemical factors such as available nitrogen and phosphorus. These findings provide data and theoretical support for a better understanding of the ecological resources of fungi in the Ebinur Lake wetland.

Culturable endophytic fungi community structure isolated from Codonopsis pilosula roots and effect of season and geographic location on their structures. BMC Microbiol 2023; 23:132.

Abstract
BACKGROUND Rhizosphere soil physicochemical, endophytic fungi have an important role in plant growth. A large number of endophytic fungi play an indispensable role in promoting plant growth and development, and they can provide protection for host plants by producing a variety of secondary metabolites to resist and inhibit plant pathogens. Due to the terrain of Gansu province is north-south and longitudinal, different climatic conditions, altitude, terrain and growth environment will affect the growth of Codonopsis pilosula, and the changes in these environmental factors directly affect the quality and yield of C. pilosula in different production areas. However, In C. pilosula, the connection between soil nutrients, spatiotemporal variation and the community structure of endophytic fungi isolated from C. pilosula roots has not been well studied. RESULTS Seven hundred six strains of endophytic fungi were obtained using tissue isolation and the hyphaend-purification method from C. pilosula roots that picked at all seasons and six districts (Huichuan, HC; Longxi, LX; Zhangxian, ZX; Minxian, MX; Weiyuan, WY; and Lintao, LT) in Gansu Province, China. Fusarium sp. (205 strains, 29.04%), Aspergillus sp. (196 strains, 27.76%), Alternaria sp. (73 strains, 10.34%), Penicillium sp. (58 strains, 8.22%) and Plectosphaerella sp. (56 strains, 7.93%) were the dominant genus. The species composition differed from temporal and spatial distribution (Autumn and Winter were higher than Spring and Summer, MX and LT had the highest similarity, HC and LT had the lowest). physical and chemical of soil like Electroconductibility (EC), Total nitrogen (TN), Catalase (CAT), Urease (URE) and Sucrase (SUC) had significant effects on agronomic traits of C. pilosula (P < 0.05). AK (Spring and Summer), TN (Autumn) and altitude (Winter) are the main driving factors for the change of endophytic fungal community. Moreover, geographic location (such as altitude, latitude and longitude) also has effects on the diversity of endophytic fungi. CONCLUSIONS These results suggested that soil nutrients and enzyme, seasonal variation and geographical locations have an impact on shaping the community structure of culturable endophytic fungi in the roots of C. pilosula and its root traits. This suggests that climatic conditions may play a driving role in the growth and development of C. pilosula.

Abstract
El Bosque de Prosperina es un área protegida ubicada en la ciudad de Guayaquil-Ecuador donde existe una gran diversidad de plantas, animales y, últimamente, microorganismos que contribuyen a su conservación y mantenimiento. Las muestras de suelo recogidas en las estaciones de Cuevas, Cañas y FCV durante la estación seca se analizaron mediante métodos microbiológicos convencionales. Como resultado, se identificaron 38 especies, y en cada estación se obtuvieron 16, 16 y 16, respectivamente. Los géneros más frecuentes encontrados en las tres estaciones son Aspergillus, Penicillium, Trichoderma y Absidia, con menor frecuencia Fusarium, Cladosporium, Talaromyces, Cur-vularia, Humicola, Gongronella, Clonostachys y Mariannea. Se crioconservaron 38 cepas de hongos filamentosos en la Colección de Cultivos de microorganismos del CIBE (CCM-CIBE), de las cuales 36 eran especies únicas. Los resultados obtenidos sugieren que las especies encontradas. Su desplazamiento puede verse afectado por factores naturales y humanos. Además, confirmamos microorganismos biocontroladores como Purpureocillium, un nematófago y Cladosporium que, pueden tener un alto potencial en actividades de biorremediación de im-portancia para la agricultura y recuperación de suelos, lo que corrobora que el Bosque de Protección es una rica fuente de microorganismos con una gran reputación para su conservación.

Abstract
Rhizoplane microbes are considered proxies for evaluating the assemblage stability of the rhizosphere in wetland ecosystems due to their roles in plant growth and ecosystem health. However, our knowledge of how microbial assemblage stability is promoted in the reed rhizosphere of wetlands undergoing recovery is limited. We investigated the assemblage stability, diversity, abundance, co-occurrence patterns, and functional characteristics of reed rhizosphere microbes in restored wetlands. The results indicated that assemblage stability significantly increased with recovery time and that the microbial assemblages were capable of resisting seasonal fluctuations after more than 20 years of restoration. The number of bacterial indicators was greater in the restoration groups with longer restoration periods. Most bacterial indicators appeared in the 30-year restoration group. However, the core taxa and keystone species of module 2 exhibited greater abundance within longer recovery periods and were well organized, with rich and diverse functions that enhanced microbial assemblage stability. Our study provides insight into the connection between the rhizosphere microbiome and recovery period and presents a useful theoretical basis for the empirical management of wetland ecosystems.
