CdSe quantum dots are often used in industry as fluorescent materials. In this study, CdSe quantum dots were synthesized using Fusarium oxysporum. The cadmium and selenium concentration, pH, and temperature for the culture of F. oxysporum (Fusarium oxysporum) were optimized for the synthesis, and the CdSe quantum dots obtained from the mycelial cells of F. oxysporum were observed by transmissio...

Dimorphism or morphogenic conversion is exploited by several pathogenic fungi and is required for tissue invasion and/or survival in the host. We have identified a homolog of a master regulator of this morphological switch in the plant pathogenic fungus Fusarium oxysporum f. sp. lycopersici. This non-dimorphic fungus causes vascular wilt disease in tomato by penetrating the plant roots and colo...

Commercially distributed garlic (Allium sativum) seed cloves from six states of the United States and mainland China were surveyed for the presence of fungi recorded as pathogenic to garlic in the literature. Aspergillus niger, A. ochraceus, Botrytis porri, Embellisia allii, Fusarium oxysporum f. sp. cepae, F. proliferatum and Penicillium hirsutum, were each recovered from one or more of these ...

Fusarium oxysporum is a devastating pathogen causing extensive yield losses in a variety of crops and development of sustainable, environmentally friendly methods to improve crop resistance is crucial. We have used Host-Delivered RNA interference (HD-RNAi) technology to partially silence three different genes (FOW2, FRP1, and OPR) in the hemi-biotrophic fungus F. oxysporum f. sp. conglutinans. ...

Three structural chitin synthase genes, chs1, chs2 and chs3, were identified in the genome of Fusarium oxysporum f. sp. lycopersici, a soilborne pathogen causing vascular wilt disease in tomato plants. Based on amino acid identities with related fungal species, chs1, chs2 and chs3 encode structural chitin synthases (CSs) of class I, class II and class III, respectively. A gene (chs7) encoding a...

Isolates of Fusarium were discovered in peat soil samples collected from peat swamp forest, waterlogged peat soil, and peat soil from oil palm plantations. Morphological characteristics were used to tentatively identify the isolates, and species confirmation was based on the sequence of translation elongation factor-1α (TEF-1α) and phylogenetic analysis. Based on the closest match of Basic Loca...

Development of tomato varieties and hybrids with resistance to the pathogen Fusarium oxysporum f sp. Lycopersici is a priority in breeding vegetable crops. Evaluation selection initial material important effective for pathogen. To do this, along classical methods breeding, method molecular marking widely used. The purpose this study was screen existing collection tomatoes markers I-2/5, I2OH At...
