fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

The aerobiology of fungi in the genus Fusarium is poorly understood. Many species of Fusarium are important pathogens of plants and animals and some produce dangerous secondary metabolites known as mycotoxins. In 2006 and 2007, autonomous unmanned aerial vehicles (UAVs) were used to collect Fusarium 40–320 m above the ground at the Kentland Farm in Blacksburg, Virginia. Eleven single-spored iso...

The effects of two Iranian medicinal plants including Zataria multiflora and Geranium pelargoniumwere evaluated on growth-inhibiting of some toxigenic fungi such as Aspergillus flavus, A. parasiticus, A.ochraceus and Fusarium verticillioides. In this study, standard Z. multiflora and G. pelargonium essentialoils (EOs) were diluted in 0.01% dimethyl sulfoxide. Different dilutions of Z. multiflor...

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 ...

To assess the potential for mating in several Fusarium species with no known sexual stage, we developed degenerate and semidegenerate oligonucleotide primers to identify conserved mating type (MAT) sequences in these fungi. The putative alpha and high-mobility-group (HMG) box sequences from Fusarium avenaceum, F. culmorum, F. poae, and F. semitectum were compared to similar sequences that were ...

The occurrence of Fusarium spp associated with pecan tree (Carya illinoinensis) diseases in Brazil has been observed in recent laboratory analyses in Rio Grande do Sul State. Thus, in this study, we i) obtained Fusarium isolates from plants with disease symptoms; ii) tested the pathogenicity of these Fusarium isolates to pecan; iii) characterized and grouped Fusarium isolates that were pathogen...
