A marine Ascidian-associated fungus, Trichoderma harzianum, (NIO/BCC2000-51) was assessed for its in vitro antagonistic activity against ten fungal phytopathogens and three food-infesting fungi. Fractionation of the cell-free culture filtrate of T. harzianum (NIO/BCC2000-51) showed its ethyl acetate (EA) fraction to be significantly active against fungal phytopathogens; Macrophomina sp, Pyricul...

Stem rot was found for the first time on the Asiatic dayflower plant (Commelina communis L.) in Korea. A detailed description of this Korean specimen is given, along with its rDNA internal transcribed spacer sequence. The fungus was identified as Sclerotium rolfsii Saccardo based on mycological characteristics and molecular data.

The fungal stroma is a distinct developmental stage, a compact mass of hyphal cells enveloped by a melanized layer of rind cells which is produced from vegetative mycelium. Two types of stromata that are characteristic of members of the Sclerotiniaceae but are also produced in a wide range of other fungi, i.e., the determinate tuberlike sclerotium and the indeterminate platelike substratal stro...

A series of 5,10,15,20-tetraphenylporphinatozirconium(IV) acetylacetonatophenolates containing different phenols as axial ligands [Zr(TPP)(Y)(X)] (TPP = 5,10.15,20-tetraphenyl-21H, 23H-porphine; Y = acac; X = different phenolates) have been synthesized and characterized by various spectrochemical studies. The complexes were also screened for antimicrobial activities. Antifungal activity of some...

In this study, we aimed to characterize fungal samples from necrotic lesions on collar regions observed in different sweetpotato growing regions during 2015 and 2016 in Korea. Sclerotia appeared on the root zone soil surface, and white dense mycelia were observed. At the later stages of infection, mother roots quickly rotted, and large areas of the plants were destroyed. The disease occurrence ...

the essential oil extracted from the epicarp of citrus sinensis exhibited absolute fungitoxicity against soybean’s fungus as alternaria alternate, aspergillus niger, cercospora kikuchii, chaetomium spp., cladosporium cladosporioides, curvularia lunata, fusarium roseum, macrophomina phaseolina, penicillium italicum, phomopsisspp. rhizoctonia solani, and sclerotium rolfsii. it is very difficult t...

In soil, plant roots coexist with bacteria and fungi that produce siderophores capable of sequestering the available iron. Microbial cyanogenesis has been demonstrated in many species of fungi and in a few species of bacteria (e.g., Chromobacterium and Pseudomonas). Fluorescent Pseudomonas isolates P29, P59, P144, P166, P174, P187, P191 and P192 were cyanogenic and produced siderophores in the ...
