Three new species of (Mycenaceae, Agaricales) from South China.

The genus within the family Mycenaceae is characterised by the gelatinous basidiomata with poroid hymenophore and most species inhabit monocotyledonous plants. In this study, many samples covering a wide geographic range in China were examined morphologically and phylogenetically using concatenated ITS1-5.8S-ITS2-nLSU sequence data.

Defensive alteration of root exudate composition by grafting sp. onto resistant rootstock contributes to reducing crown gall disease.

Grafting is a traditional and significant strategy to suppress soil-borne diseases, such as the crown gall disease caused by tumorigenic and . Root exudates and the rhizosphere microbiome play critical roles in controlling crown gall disease, but their roles in suppressing crown gall disease in grafted plants remain unclear. Here, disease-susceptible cherry rootstock 'Gisela 6' and disease-resistant cherry rootstock 'Haiying 1' were grafted onto each other or self-grafted.

Species diversity of pathogenic wood-rotting fungi (Agaricomycetes, Basidiomycota) in China.

Wood-rotting basidiomycetes have been investigated in the Chinese forest ecosystem for the past 30 years. Two hundred and five pathogenic wood-decayers belonging to 9 orders, 30 families, and 74 genera have been found in Chinese native forests, plantations, and gardens. Seventy-two species (accounting for 35% of the total pathogenic species) are reported as pathogenic fungi in China for the first time.

Two new species of (Russulales, Basidiomycota) in Southwest China.

Two new species of viz. and , are described from southwest China. Phylogeny based on ITS + nLSU dataset demonstrates that samples of the two species form two independent lineages and are different in morphology from the existing species of .

Two new species of (Polyporales, Basidiomycota) from China and Ecuador based on morphology and phylogeny.

At present, 25 species are accepted in and are distributed in Asia, Europe, North America, South America, Australia, and Africa. In this study, two new species, from Ecuador and from China, are described and illustrated based on morphological examination and phylogenetic analyses. is characterized by annual, resupinate basidiomata with pinkish buff to honey yellow hymenophore when dry, round to angular pores of 2-4 per mm, a dimitic hyphal structure with generative hyphae bearing clamp connections, hyphae at dissepiment edge usually with one or two simple septa, the presence of dendrohyphidia and cystidioles, and oblong to ellipsoid basidiospores measuring 14.

CLA178-Induced Systemic Resistance of Against Crown Gall Disease.

Plant growth-promoting rhizobacteria (PGPRs) are able to activate induced systemic resistance (ISR) of the plants against phytopathogens. However, whether and how ISR can be activated by PGPRs in plants of the genus is unclear. The effects of PGPR CLA178 and the pathogen C58 on the growth, plant defense-related genes, hormones, and reactive oxygen species (ROS) in the rose plants were compared.

Effect of Shading and Forest Type on Morphological Characteristics and Bioactive Compounds of Fruiting Bodies of Songshan Lingzhi Ganoderma tsugae (Agaricomycetes).

Ganoderma tsugae strain MCCCMAS0053 cultivation on short logs results in varied yield and quality under different growth conditions. Thus, growth conditions need optimization to increase yield and quality. An indoor experiment with three shade treatments (A1, two layers of black sun-shade net; A2, one layer of black sun-shade net plus plastic mulch; A3, one layer of black sun-shade net) and a field experiment in two forest types (pine or mixed pine-oak) were conducted.

Reduced Root Secretion of Valine in -Microbe Interaction Contributes to the Decreased Colonization of Pathogenic .

Root exudates play a critical role in root-microbe interactions. causes crown gall disease in multiple plant species, but rose root exudate-mediated inhibition of in the rhizosphere is poorly understood. In this study, the influence of preinoculation with beneficial bacteria or pathogens on root exudates and subsequent colonization by was investigated in a split-root system.

Morphological and molecular evidence for three new species of Coltricia (Hymenochaetaceae, Basidiomycota) from southern China.

Three new species of Coltricia from southern China are described on the basis of morphological characters and molecular analyses. Phylogenetic analyses based on nuc rDNA ITS1-5.8S-ITS2 and partial 28S rDNA, and partial sequences of genes for RNA polymerase II subunits 1 and 2 confirmed the generic placement of the three new species.
