Cheng CY, Zhang MY, Niu YC, Zhang M, Geng YH, Deng H. Comparison of Fungal Genera Isolated from Cucumber Plants and Rhizosphere Soil by Using Various Cultural Media. J Fungi (Basel) 2023; 9:934. [PMID: 37755042 PMCID: PMC10532442 DOI: 10.3390/jof9090934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 09/06/2023] [Accepted: 09/11/2023] [Indexed: 09/28/2023] Open
Abstract
Plant endophytic fungi and rhizosphere soil fungi are often reported as biocontrol agents against plant pathogens or with plant growth promotion potential. Four treatments were performed in field and greenhouse experiments where cucumber plants were inoculated with Trichoderma harzianum and Fusarium oxysporum in 2022. The roots, stems and leaves of cucumber plants and their rhizosphere soil were collected twice individually from the field and greenhouse for isolation of cucumber endophytic and rhizosphere soil fungi. All fungal strains were identified through sequence similarity of the ITS1-5.8s-ITS2 rDNA region. The potato dextrose agar (PDA) media yielded the highest number of genera isolated from cucumber plants, rhizosphere soil and both compared to other media. There were no significant differences among the four media for the isolation of all cucumber endophytic fungi. However, in the roots, the number of endophytic fungi isolated by MRBA was significantly higher than that isolated on malt extract agar (MEA), while in the stems, the number of fungi isolated with PDA was significantly higher than that isolated with Martin's rose bengal agar medium (MRBA). PDA had significantly higher isolation efficiency for the rhizosphere soil fungi than MRBA. The 28 fungal genera had high isolation efficiency, and the endophytic Trichoderma strains were significantly more isolated by MEA than those of MRBA. It is suggested that PDA can be used as a basic medium, and different cultural media can be considered for specific fungal genera.

Antagonistic Activity of Fungal Strains against Fusarium Crown Rot. PLANTS 2022; 11:plants11030255. [PMID: 35161236 PMCID: PMC8838148 DOI: 10.3390/plants11030255] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 01/12/2022] [Accepted: 01/13/2022] [Indexed: 11/17/2022]
Abstract
The crown rot of wheat is a destructive soil-borne pathogen that severely reduces the yield and quality of wheat. This study aimed to screen and identify the antagonistic strains against Fusarium pseudograminearum (Fp), which is the dominant pathogen associated with the crown rot of wheat in China, and evaluate their biosynthetic potential. The antagonistic strains were screened via a dual-culture antagonism assay, and then identified by combining the morphological characteristics and internal transcribed spacer gene sequencing. The polyketide synthases (PKS-I and PKS-II) and non-ribosomal peptide synthetase (NRPS) genes in the antagonistic strains were detected via specific amplification of chromosomal DNA. Eleven out of 157 fungal strains, including six strains with matrix competition and five strains with antibiosis, were obtained. The eleven antagonistic strains belonged to the following four genera: Alternaria, Botryosphaeria, Phoma and Talaromyces. The inhibition rate of six strains with matrix competition was greater than 50%, with B. dothidea S2-22 demonstrating the highest at 80.3%. The width of the inhibition zone of T. trachyspermus R-17 among the five strains with antibiosis was the widest at 11 mm. Among the eleven antagonistic strains, three strains of A. alternata and the strain P. moricola only contained the PKS-II gene, the strain A. tenuissima contained PKS-I and PKS-II genes, three strains of B. dothidea contained PKS-II and NRPS genes, while three strains of T. trachyspermus did not contain any genes. These results demonstrated potential strains for the biocontrol of the crown rot of wheat. In particular, T. trachyspermus R-17 can be investigated further as a promising agent, and the active substances secreted by antagonistic strains may be synthesized by other pathways.

Abstract
Fusarium wilt is an important disease of many food crops and often causes serious damages to yield and food quality. Consequently, numerous studies mainly focused on exploring the control strategy for Fusarium oxysporum as well as the mechanism of interaction between the F. oxysporum and other beneficial soil microorganisms. In this study, we have screened and identified an efficient biocontrol strain from the soil with infection of F. oxysporum f. sp. momordica (referred to as Fom), Talaromyces purpurogenus Q2 (referred to as TpQ2), which could be effective to reduce relative abundance of the rhizospheric Fom, leading to a significant decrease of Fusarium wilt disease incidence in bitter gourd during the greenhouse and field trails. TpQ2 can reduce the relative abundance of rhizospheric Fom through inhibition of growth and development of Fom. During the co-cultivation of TpQ2 and Fom, we confirmed that TpQ2 could significantly suppress the growth and development of Fom through disturbing the normal hyphae shape and function of the cell walls of Fom via secreting cell wall–degrading enzymes and suppression of the expression of cell wall biosynthesis genes, such as FomCFEM. In the meantime, TpQ2 showed a strong negative correlation with F. oxysporum in soil and positive correlation with beneficial indigenous microorganisms that had significant negative correlation with Fusarium populations, such as Streptomycetes, Lysobacter, and Sphingobium. To summarize, TpQ2 has a good biocontrol efficacy on Fusarium wilt of bitter gourd. The biocontrol mechanisms of TpQ2 on Fusarium wilt are complex and diverse.

Abstract
Three novel fungal species, Talaromyces gwangjuensis, T. koreana, and T. teleomorpha were found in Korea during an investigation of fungi in freshwater. The new species are described here using morphological characters, a multi-gene phylogenetic analysis of the ITS, BenA, CaM, RPB2 regions, and extrolite data. Talaromyces gwangjuensis is characterized by restricted growth on CYA, YES, monoverticillate and biverticillate conidiophores, and globose smooth-walled conidia. Talaromyces koreana is characterized by fast growth on MEA, biverticillate conidiophores, or sometimes with additional branches and the production of acid on CREA. Talaromyces teleomorpha is characterized by producing creamish-white or yellow ascomata on OA and MEA, restricted growth on CREA, and no asexual morph observed in the culture. A phylogenetic analysis of the ITS, BenA, CaM, and RPB2 sequences showed that the three new taxa form distinct monophyletic clades. Detailed descriptions, illustrations, and phylogenetic trees are provided.

Abstract
Talaromyces is a monophyletic genus containing seven sections. The number of species in Talaromyces grows rapidly due to reliable and complete sequence data contributed from all over the world. In this study agricultural soil samples from Fujiang, Guangdong, Jiangxi, Shandong, Tibet and Zhejiang provinces of China were collected and analyzed for fungal diversity. Based on a polyphasic approach including phylogenetic analysis of partial ITS, BenA, CaM and RPB2 gene sequences, macro- and micro-morphological analyses, six of them could not be assigned to any described species, and one cannot be assigned to any known sections. Morphological characters as well as their phylogenetic relationship with other Talaromyces species are presented for these putative new species. Penicillium resedanum is combined in Talaromyces section Subinflati as T. resedanus.

Abstract
The genera Kernia and Acaulium comprise species commonly isolated from dung, soil, decaying meat and skin of animal. The taxonomy of these fungi has been controversial and relies mainly on morphological criteria. With the aim to clarify the taxonomy and phylogeny of these fungi, we studied all the available ex-type strains of a large set of species by means of morphological and molecular phylogenetic analyses. Phylogenetic analysis of the partial internal transcribed spacer region (ITS) and the partial 28S rDNA (LSU) showed that the genera Kernia and Acaulium were found to be separated in two distinct lineages in Microascaceae. Based on morphological characters and multilocus phylogenetic analysis of the ITS, LSU, translation elongation factor 1α and β-tubulin genes, the species in Kernia and Acaulium were well separated and two new combinations are introduced, i.e. Acaulium peruvianum and Acaulium retardatum, a new species of Kernia is described, namely Kernia anthracina. Descriptions of the phenotypic features and molecular phylogeny for identification are discussed for accepted species in two genera in this study.

Abstract
Talaromyces halophytorum sp. nov. was isolated from the roots of halophyte Limonium tetragonum collected from Seocheon-gun, Korea in November 2015. It showed a slow growth on yeast extract sucrose agar at 25 °C, no growth at 4 °C or 37 °C and produced smooth-walled and globose to sub-globose conidia. T. halophytorum is phylogenetically distinct from the other reported Talaromyces species of section Trachyspermi based on multi-locus sequence typing results using partial fragments of β-tubulin, calmodulin, ITS, and RNA polymerase II genes.

Abstract
Coprophilous fungi are saprotrophic organisms that show great diversity, mainly on herbivore dung. The physico-chemical characteristics of this peculiar substrate combined with the high level of fungal adaptation to different environmental conditions offer the perfect setting for discovering new taxa. This study focused on the species diversity of penicillium-like fungi isolated mainly from herbivore dung collected at different Spanish locations. From 130 samples, a total of 104 isolates were obtained, and 48 species were identified. Preliminary identifications were based on morphology and partial β-tubulin (tub2) gene sequences. Putative new taxa were characterized by a multi-gene sequencing analysis testing the tub2, the internal transcribed spacer rDNA (ITS), calmodulin (cmdA), and RNA polymerase II second largest subunit (rpb2) genes, and a detailed phenotypic study. Using this polyphasic approach and following the genealogical concordance phylogenetic species recognition (GCPSR) method, we propose the new genera Penicillago (for Penicillium nodositatum) and Pseudopenicillium (for Penicillium megasporum and P. giganteum) in the family Aspergillaceae, and 11 new species, including seven Penicillium, three Talaromyces and one Pseudopenicillium. A lectotype and epitype are designed for Penicillium nodositatum. Our results show that the species diversity of penicillium-like fungi on herbivore dung has not been widely studied and that this substrate seems to be a good reservoir of interesting Eurotialean fungi.

Abstract
A new Talaromyces species, T.amyrossmaniae, isolated from decaying fruit and litter of Terminalia bellerica, is described and illustrated. On the natural substrate, the new species produces determinate synnemata, with a well-defined, vivid orange red to orange red cylindrical stipe, and a greyish green capitulum. Conidiophores are typically biverticillate, or sometimes have subterminal branches, with acerose phialides that produce globose to subglobose, smooth to slightly roughened conidia. Multigene phylogenetic analyses based on the internal transcribed spacer region (ITS), and partial sequences of β-tubulin (BenA), calmodulin (CaM), and DNA directed RNA polymerase second large subunit (RPB2) genes, along with morphological characterization, revealed that these isolates are distinct and form a unique lineage of Talaromyces in section Trachyspermi, closely allied to T.aerius, T.albobiverticillius, T.heiheensis, T.erythromellis, and T.solicola. The new species T.amyrossmaniae is the first species in section Trachyspermi with determinate synnemata.
