Isozyme phenotypes were determined for 101 strains of Gibberella fujikuroi and 2 strains of Gibberella nygamai that represent seven biological species (mating populations) isolated from a variety of plant hosts in dispersed geographic locations. Fourteen enzymes were resolved in one or more of three buffer systems. Two of the enzymes, arylesterase and acid phosphatase, were polymorphic within t...

Thirty-nine Arthroderma vanbreuseghemii isolates identified by mating behavior were assayed to determine their ribosomal RNA gene internal transcribed spacer (ITS) region genotypes. Twenty-two isolates of mating type (+) and 4 of (-) showed the genotype of Trichophyton mentagrophytes var. interdigitale, 9 isolates of mating type (+) and 4 of (-) showed the genotype of A. vanbreuseghemii. Nine o...

We investigated the sexual reproductive mode of the two most important etiological agents of soybean sudden death syndrome, Fusarium tucumaniae and Fusarium virguliforme. F. tucumaniae sexual crosses often were highly fertile, making it possible to assign mating type and assess female fertility in 24 South American isolates. These crosses produced red perithecia and oblong-elliptical ascospores...

Alfalfa Fusarium Root Rot (AFRR) is a serious soil-borne disease with complex pathogenicity. Diseased samples suspected of AFRR were collected from Hohhot, Ordos, Hulunbeier, Chifeng, and Bayannur in Inner Mongolia, China, leading to 317 isolates. The isolates identified as acuminatum, F. solani, equiseti, incarnatum, oxysporum, avenaceum, verticillioides, proliferatum, falciforme, tricinctum, ...

Fusarium proliferatum as a common fungus pathogen in foods can produce toxic fumonisins, which can cause animal diseases and increase risks of human cancers. On contrary, butylated hydroxyanisole (BHA) as a synthetic antioxidant offers a clue for preventing growth of fungal species and inhibiting production of mycotoxins. Unfortunately, information of the inhibitory mechanism of BHA on Fusarium...

To avoid the use of agrochemicals in agriculture, alternative methods are emerging to control plant pathogens. Some growth-promoting rhizobacteria (PGPR) can be used as biocontrol agents since they induce protection against The aim this study was evaluate protective effect several PGPR strains main Fusarium species involved asparagus decline syndrome (ADS): F. proliferatum, oxysporum f. sp. asp...

The purpose of this study was to identify the Fusarium species associated with selected medicinal plant species of Lamiaceae and Asteraceae in Kerman, the second-largest province of Iran. The plants showing wilting/rotting symptoms as well as asymptomatic plants were collected from main medicinal plants reservoirs and production areas. Fusarium species were identified based on...

Pathological interrelations of two soil-borne diseases in cucurbits (watermelon, oriental melon, shintosa and cucumber) caused by Fusarium isolates (FI) and the root-knot nematode (RKN), Meloidogyne incognita were characterized by the fusarium disease severity index (DI), RKN gall index (GI) and eggmass index (EI) in inoculation tests using FI and RKN. Virulence of FI as determined by DI at 4 w...
