“…In our study, the endophytic strain mainly degraded carbohydrates and carboxylic acids, which are the main sources of metabolic changes in cells [71], but other carbon sources such as amino acids and polymers have also been consumed. Similarly, in the study by Barrera et al [66] on the carbon assimilation by 10 strains from the genus Cladorrhinum, carbohydrates were mainly utilized by most strains. Only three strains, C. foecundissimum CBS 180.66, C. samala INTA-AR 1, and C. bulbillosum INTA-AR 54, used mainly esters or polymers.…”

“…This system is a rapid method for the analysis of the catabolic potential of a fungal community or fungal strain pure culture based on their abilities to utilize 95 carbon substrates [64]. The BIOLOG method has been applied previously to assess functional diversity and nutritional profiles of individual fungal species [65,66], to test the nutritional competition between fungal pathogens and beneficial strains [67], and to distinguish closely related cultures [64,[68][69][70].…”

Biocontrol Potential and Catabolic Profile of Endophytic Diaporthe eres Strain 1420S from Prunus domestica L. in Poland—A Preliminary Study

Recently, Diaporthe has been considered the most frequently isolated genera of endophytic fungi, having a broad spectrum of host plants and a worldwide distribution. The endophytic Diaporthe strain used in the present work came from the Fungal Collection of Phytopathology and Mycology Subdepartment, University of Life Sciences in Lublin (Poland), and was isolated from healthy Prunus domestica shoots during previous studies. Due to the possibility of using the Diaporthe endophytes as a promising option for plant disease management, the main goal of the research was to study the antagonistic effect of endophytic Diaporthe strain against six phytopathogens: Verticillium dahliae, Botrytis cinerea, Fusarium avenaceum, F. sprotrichioides, Alternaria alternata, and Trichothecium roseum based on the dual culture assay and to determine the catabolic profile of the endophyte by using Biolog FF Plates. The dual-culture test assay revealed the ability of the endophytic Diaporthe to limit the growth of all tested pathogens. The growth inhibition percentage ranged from 20% (V. dahliae) to 40% (T. roseum). A distinct zone of inhibition occurred between the endophytic Diaporthe and the pathogens T. roseum, V. dahliae, and B. cinerea in the co-growth combinations. As for the catabolic profile results, the most intensive utilization of carbon substrates was observed after 168 h of incubation. The growth of the analyzed strain was observed on 79 media containing carbohydrates, carboxylic acids, amino acids, amines and amides, polymers, and others. The most effective decomposition was observed in the polymers group, the least in amines and amides. Molecular identification indicated that this strain was closely related to the Diaporthe eres species complex.

“…These rhizosphere microorganisms played an important role in plant growth and the inhibition of pathogenic microorganisms [ 39 – 43 ]. By contrast, some potentially pathogenic microorganisms, such as Cercophora [ 44 ], Alternaria , Paraphoma , Cladosporium [ 45 ], Monographella [ 46 ], Hydropisphaera [ 47 ], and Colletotrichum were significantly amplified. For example, Alternaria and Paraphoma can cause root rot of B. chinense [ 25 , 48 ], and Colletotrichum can infect leaves to produce disease spots [ 49 ] .…”

The effects of cropping practices on the rhizosphere soil physical properties and microbial communities of Bupleurum chinense have not been studied in detail. The chemical properties and the microbiome of rhizosphere soil of B. chinense were assessed in the field trial with three cropping practices (continuous monocropping, Bupleurum-corn intercropping and Bupleurum-corn rotation). The results showed cropping practices changed the chemical properties of the rhizosphere soil and composition, structure and diversity of the rhizosphere microbial communities. Continuous monocropping of B. chinense not only decreased soil pH and the contents of NO3−-N and available K, but also decreased the alpha diversity of bacteria and beneficial microorganisms. However, Bupleurum-corn rotation improved soil chemical properties and reduced the abundance of harmful microorganisms. Soil chemical properties, especially the contents of NH4+-N, soil organic matter (SOM) and available K, were the key factors affecting the structure and composition of microbial communities in the rhizosphere soil. These findings could provide a new basis for overcoming problems associated with continuous cropping and promote development of B. chinense planting industry by improving soil microbial communities.

“…Our results showed that Ascomycota and Basidiomycota were the dominant phyla identified in the two rhizosphere groups. Fungi from the Ascomycota are effective contributors in controlling plant pathogens, promoting plant development, and regulating carbon and nitrogen cycling in arid ecosystems ( 28 , 29 ). Similarly, fungi from Basidiomycota are well documented as promising agents for carbon recycling, ecosystem functioning, and medicinal properties ( 30 ).…”

Our study highlighted the importance of rhizosphere fungal communities in an endangered plant, S. tsinyunensis . Comparative analysis of soil samples in nearly all extant S. tsinyunensis populations identified that soil properties, especially soil water content, might play essential roles in the survival and expansion of S. tsinyunensis .
