Morphological and phylogenetic analyses reveal two new species (Pleosporales, Pleosporaceae) in section from Cucurbitaceae plants in China.

species are commonly found as saprophytes, endophytes and plant pathogens. During a survey of small-spored in China, two new species were discovered from Cucurbitaceae plants collected in Hubei and Sichuan provinces. This study identified two new species of using seven genes (ITS, , , , , , and OPA10-2) for phylogenetic analyses and morphological characteristics.

Seven New Species of Eurotiales (Ascomycota) Isolated from Tidal Flat Sediments in China.

Tidal flats have been reported to contain many microorganisms and play a critical role in maintaining biodiversity. In surveys of filamentous fungi from tidal flat sediments in China, seven new species of Eurotiales were discovered and described. Morphological characteristics and DNA sequence analyses of combined datasets of the , , and regions support their placements and recognition as new species.

New Species of Large-Spored in Section Associated with Compositae Plants in China.

is a ubiquitous fungal genus including saprobic, endophytic, and pathogenic species associated with a wide variety of substrates. It has been separated into 29 sections and seven monotypic lineages based on molecular and morphological data. sect.

Analysis of Phyllosphere Microorganisms and Potential Pathogens of Tobacco Leaves.

In the tobacco phyllosphere, some of the microbes may have detrimental effects on plant health, while many may be neutral or even beneficial. Some cannot be cultivated, so culture-independent methods are needed to explore microbial diversity. In this study, both metagenetic analysis and traditional culture-dependent methods were used on asymptomatic healthy leaves and symptomatic diseased leaves of tobacco plants.

and , Two New Records on in China.

Two species isolated from fruit of in China were characterized based on morphology and multilocus phylogeny of ITS, , and gene sequences. The phylogeny indicated that the two species match and . A critical examination of phenotypic characteristics confirmed the phylogenetic results.

Morphological and molecular identification of two new species (Ascomycota, Pleosporaceae) in section Radicina from China.

The fungal genus was distributed widely and found in different habitats such as plant or indoor environment. During an investigation into this genus in China, two new species, and were respectively isolated from diseased leaves of and , which both belonged to Umbelliferae. Phylogenetically, they were determined as new species belonging in the section Radicina of based on the combined four gene fragments of ITS, , and .

Metabolic Phenotype Characterization of , the Causal Agent of Gray Mold.

, which causes gray mold, is an important pathogen in four important economic crops, tomato, tobacco, cucumber and strawberry, in China and worldwide. Metabolic phenomics data on isolates from these four crops were characterized and compared for 950 phenotypes with a BIOLOG Phenotype MicroArray (PM). The results showed that the metabolic fingerprints of the four isolates were similar to each other with minimal differences.

[Comparison of genomes between Aspergillus nidulans and 30 filamentous ascomycetes].

To investigate the conserved homologs of filamentous ascomycetes genomes, the local fungal genome database used in this analysis was established, which consisted of 31 latest and complete genome data publicly available on the Internet. An expectation value cutoff of 0.1 was used to identify significant hits.
