Fungal Secondary Metabolites: Fusarium spp. and Microdochium spp.
(2022-12-06)The key characteristic of aurofusarin is the repellent effect against fungivores. We confirmed the previous finding that the red pigment aurofusarin is a water-insoluble metabolite, and it is preferably soluble in non-polar ... -
Genome sequencing and phylogenetic analyses of common and dwarf bunt of wheat provide insights into their genomic diversity and species boundaries, and enable the development of a detection assay for Tilletia controversa
(2021-11-23)The fungal genus Tilletia is generally recognized by the production of darkly pigmented teliospores, which replace mostly the host ovary. Currently, nearly 200 species of Tilletia species infecting Poaceae are included in ... -
Plant Secondary Metabolites Allelopathic Functions and Biomedical Potential
(2021-07-07)Secondary metabolites can contribute to the plant’s survival in the ecosystem in various ways. They include allelochemicals involved in interactions with microorganisms, herbivores, and other plants sharing the same ... -
Biomedical Applications and Secondary Metabolite Profiling of Hyoscyamus niger and Sesamum indicum Seed, Root and Hairy Root Cultures
(2020-12-11)Nature has been known to be a rich source of pharmacologically essential compounds over the years. Phytochemical studies have revealed a large number of natural products with a unique chemical structure and important medical ... -
Interactions between invertebrate and mycotoxin-producing fungi
(2018-12-12)Interactions between fungi and invertebrates nearly occur in every ecosystem. Grazing affects fungal biomass density and is species-dependent. However, how invertebrates affect mycotoxin-producing fungi has not been studied ... -
Biosynthesis and biological function of phosphonates in Fusarium spp.
(2018-04-09)Phosphonates are natural or synthetic compounds with a direct carbon-phosphorus bond. Their similarity to the abundant phosphate esters and carboxylic acids and the stability of the C-P bond makes them suitable for diverse ... -
Microbiological and Food Safety Aspects of Tempeh Production in Indonesia
(2018-03-20)Tempeh is traditional food from Indonesia made by fermenting soybeans with mold Rhizopus spp. It has solid form, distinctive aroma and white and slightly gray. Indonesia is known for the largest tempeh production in the ... -
Plant Root Exudates
(2017-02-09)Root exudates represent complex mixtures of low-molecular-weight and high-molecular-weight compounds. The former comprise predominantly primary and secondary plant metabolites, the latter mucilage precursors and some ... -
Effect of mycotoxin production on interactions between Fusarium species during maize infection and on the production of volatile metabolites
(2017-02-02)Maize (Zea mays L.) is an important cereal crop which provides staple food for humans and livestock. Maize cultivation is threatened by numerous microbial diseases under field conditions. Fungal pathogens belonging to ... -
Biological Detoxification of Enniatins
(2017-01-09)Summary: Mycotoxins are secondary metabolites produced by fungi. Enniatins are a group of cyclohexadepsipeptides made of three hydroxyisovaleric acid molecules and alternating amino acids mostly valine, leucine and isoleucine. ... -
High Fumonisin Content in Maize: Search for Source of Infection and Biological Function
(2014-05-22)Fusarium is a large and complex genus, comprises important pathogens most of which are able to produce mycotoxins. Maize is a host of several Fusarium species that cause ear rot, kernel rot, stalk rot and also seedling ... -
Secondary metabolites in fungal biotic interactions
(2014-05-22)Fungi are known for their production of chemical and biological diversity of secondary metabolites. To understand the structure, biological activity and function of fungal secondary metabolites contribute to the development ... -
Chemical interactions between Verticillium longisporum and oilseed rape Brassica napus
(2014-05-20)Verticillium longisporum is a devastating vascular pathogen which infects plants from Brassicacae including oilseed rape Brassica napus, the pathogen infects the plant through the root and enters the vascular system to ... -
Analysis of toxigenic fungi and their mycotoxins in biotic interactions
(2014-02-12)Filamentous fungi are producers of a broad range of secondary metabolites with a high diversity of biological activities. It is generally assumed that the production of these metabolites leads to benefits which allow the ... -
New Strategies for the Detection of <i>Fusarium</i> Infection and Mycotoxin Contamination of Cereals and Maize
(2013-08-13)Fusarium diseases occur worldwide in important agricultural crops and lead to the reduction of yield, seed quality and contamination of food commodities with toxic secondary metabolites, so called mycotoxins. The ... -
Determination of fungal gene expression in planta by qRT-PCR and characterization of putative pathogenicity related genes of Verticillium longisporum
(2013-02-26)Genes of Verticillium longisporum potentially involved in the pathogenicity of the fungus were identified in previous studies. The purpose of this work was to characterize some of these genes. Short transcript-derived ... -
Chemical and Genetic Diversity in Sesame (Sesamum indicum L.)
(2012-06-12)Biological diversity exist between species and within species among populations and individuals. Intraspecies diversity has been extensively studied at the genome level but intraspecies diversity in metabolic constitution ... -
Molecular and functional characterization of potential pathogenicity related genes from <i>Verticillium longisporum</i>
