Vascular wilt, caused by the infection of soil-borne pathogen Fusarium oxysporum (Fo), is one most destructive diseases many crops, including legumes such as grass pea (Lathyrus sativus), with several formae speciales (ff. spp.) defined according to their hosts. Commonly described host-specific, Fo could, in some cases, show a broader host range comprising related plant species, making its char...

Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...

The presence of lysine (Lys) or arginine (Arg) and tryptophan (Trp) are important for the antimicrobial effects of cationic peptides. Therefore, we designed and synthesized a series of antimicrobial peptides with various numbers of Lys (or Arg) and Trp repeats [(KW and RW)(n)-NH(2), where n equals 2, 3, 4, or 5]. Antifungal activities of these peptides increased with chain length. Light microsc...

The emergence of nanobiotechnology has exposed the greener methods of preparation and application. Many theoretical and experimental works have been conducted in the biosynthesis of various nanomaterials and nanocomposites. Biologically synthesised nanomaterials are exhibiting excellent, unique and optimised properties. Micro organisms play an important role in the detoxification of metals thro...

Multiple studies confirm laccase role in fungal pathogenicity and lignocellulose degradation. In spite of broad genomic research, laccases from plant wilt pathogen Fusarium oxysporum are still not characterized. The study aimed to identify F. oxysporum genes that may encode laccases sensu stricto and to characterize the proteins in silico in order to facilitate further research on their impact ...

The Role of Endophytic Fungi Isolated from Native Iranian Yew (Taxus baccata) in Biological Control Fusarium oxysporum

BERNADOVIČOVÁ, S., IVANOVÁ, H. 2011. Hyphomycetes and Coelomycetes fungi isolated from affected leaves and twigs of cherry laurel trees. Folia oecol., 38: 137–145. The aim of this work was to identify fungi occurring on leaves and twigs of Prunus laurocerasus L. Mycological observations were carried out on leaves and twigs collected from symptomatic cherry laurels growing in green areas of the ...

Plant diseases are a threat for global food safety. Allium obliquum, Allium fistulosum, Allium ursinum, Aloe vera, Berberis vulgaris and Chelidonium majus plant extracts were obtained by the repercolation method and the antifungal activity was determined by the agar-dilution assay against Apergillus niger, Botrytis cinerea, Botrytis paeoniae, Fusarium oxysporum f. sp. gladioli, Fusarium oxyspor...

Fusarium oxysporum species complex (FOSC) isolates were obtained from celery with symptoms of Fusarium yellows between 1993 and 2013 primarily in California. Virulence tests and a two-gene dataset from 174 isolates indicated that virulent isolates collected before 2013 were a highly clonal population of F. oxysporum f. sp. apii race 2. In 2013, new highly virulent clonal isolates, designated ra...
