Bacterial wilt of tomatoes, caused by Ralstonia solanacearum, is a significant soilborne disease that often causes reductions in the yield tomatoes. Dark septate endophytic fungi (DSE) represent potential biocontrol agents against plant pathogens can also enhance growth. To collect DSE with for biocontrol, fungus Cladophialophora guangxiense HX2 was isolated from rhizosphere soil sugarcane Hengzhou Guangxi Province, China, and novel species identified based on morphological properties DNA sequence analysis. C. demonstrated controlling effect 76.7% tomato bacterial promoted 0.5-fold increase seedling height. It colonized roots, enhancing activity antioxidant defensive enzyme systems. Transcriptomic qPCR approaches were used to study induction response strain infection comparing gene expression profiles. Gene ontology (GO) Kyoto Encyclopedia Genome (KEGG) pathway enrichment revealed tomatoes produce salicylic acid metabolism, ethylene-activated signaling, photosynthesis, phenylpropanoid biosynthesis infection. The IAA4 (3.5-fold change), ERF1 Hqt (1.5-fold change) substantially enhanced Hsc 70 (0.5-fold significantly reduced treatment group. This provides theoretical foundation further investigation into as biological agent prevention control wilt.

Neocordana species mainly causes leaf spots on Musa spp.(banana and plantain) Canna denudata (an ornamental plant).Leaf spp.reduce the quality of commodity result in significant economic loss.Based molecular morphological data, genus accommodates seven at present with a worldwide distribution.Most taxonomic work has been conducted musae.In this study, updates diversity, distribution, morpho-molecular taxonomy are provided.In addition, important aspects such as pathogenicity, disease control, antagonistic activity association other pathogenic fungi discussed.The phylogenetic relationships genera family Pyriculariaceae based LSU ITS DNA sequence data investigated.Our results support monophyletic nature which is sister to Barretomyces.This study provides first comprehensive account taxonomy, pathogenicity Neocordana.

A group of seven isolates black meristematic fungi was collected from rocks within the framework mycological research focused on study diversity rock-inhabiting James Ross Island in Antarctica. Their identification based ITS rDNA sequence comparisons supported by morphological data. Obtained results assigned four analysed strains as Oleoguttula mirabilis and three Rachicladosporium antarcticum. To best our knowledge this is second report isolation these two psychrophilic species different parts which imply that they probably represent a common part its environmental microbial flora.

The genus Cladophialophora was established in 1980. Prior to this study, a total of 63 species had been validated and assigned genus. members have recognized as human pathogens that cause chromoblastomycosis various other skin diseases. Beyond its pathogenic role, some are associated with range lifestyles, phytopathogens, endophytic fungi, saprobic rock-inhabiting lichenicolous fungi. In we present background information recent research progress regarding the by elucidating taxonomic history, diversity, classification outline, ecology, geographical distribution. Additionally, phylogenetic placement has updated based on multi-gene analyses. Moreover, issues perspectives summarized. This article provides researchers valuable increases understanding Cladophialophora, which will be useful for further (taxonomy, phylogeny, distribution, ecological roles medical fields)
