Objective: Fusarium diseases that cause grain mold and stalk rot of millet are the most important diseases, of these crops in Iran. Fusarium can cause stalk rots, ear rots, and grain mold, resulting in serious production losses in millet, and produce mycotoxins that are harmful to both humans and domesticated animals.  Methods: A total of 23 Fusarium isolates were rec...

Broomrapes (Orobanche spp.) are parasitic weeds and considered as a major limiting factor for the cultivation of various crops in many parts of the world. Due to the special biology of broomrape, including seed production, dispersal and longevity, the control of these species are often extremely difficult. Broomrape poses a serious threat to Iran’s agriculture; therefore exploring potential bio...

Pokkah Boeng is a serious disease of sugarcane, which can lead to devastating yield losses in crop-producing regions, including southern China. However, there is still uncertainty about the causal agent of the disease. Our aim was to isolate and characterize the pathogen through morphological, physiological, and molecular analyses. We isolated sugarcane-colonizing fungi in Fujian, China. Isolat...

Most species of Fusarium that produce fumonisin mycotoxins produce predominantly B fumonisins (FBs). However, Fusarium oxysporum strain O-1890 produces predominantly C fumonisins (FCs). In this study, the nucleotide sequence of the fumonisin biosynthetic gene (FUM) cluster in strain O-1890 was determined. The order and orientation of FUM genes were the same as in the previously described cluste...

fusarium verticillioides (f. verticillioides) is not only a primary pathogen of maize, but also can causedisease in other crops such as sorghum. pathogenicity is related to mycotoxin production such as fumonisin.in the present study, 24 isolates of f. verticillioides, which were previously identified by phenotype basedmethods, were re-identified using restriction fragment length polymorphism (r...

In a course of survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characteristics, 32 Fusarium species were i...

Background and Purpose: Fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. Contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. Accordingly, in this study, we aimed to evaluate the effects of Candida parapsilosis on the growth and fumonisin production ...

Mycotoxins pose a challenge to a safe food supply worldwide, and their threat is expected to worsen with our changing climate. The need for diligence is exemplified by the discovery of fumonisin B2 in wine, which joins ochratoxin A as a mycotoxin of concern in the grape-wine chain. To elucidate the mycotoxin risk in southeastern American wine, grape samples were collected from vineyards during ...

New cultivars of sorghum are being developed for increased food use, as livestock feed, and for the bioenergy industry by manipulation of secondary metabolic pathways through breeding. Previous work has suggested that such modifications may have an impact on cultivar response to fungal pathogens. We investigated four inoculation strategies that may be used in studies involving pathogens of sorg...
