Ear rot is a serious disease that affects maize yield and grain quality worldwide. The mycotoxins are often hazardous to humans and livestock. In samples collected in China between 2009 and 2014, Fusarium verticillioides and F. graminearum species complex were the dominant fungi causing ear rot. According to the TEF-1α gene sequence, F. graminearum species complex in China included three indepe...

During 2006 and 2007, a total of 64 Thai dried coffee bean samples (Coffeaarabica) from two growing sites in Chiangmai Province and 32 Thai dried coffeebean samples (Coffea canephora) from two growing sites in Chumporn Province,Thailand, were collected and assessed for fumonisin contamination by blackAspergilli. No Fusarium species known to produce fumonisin were detected, b...

Millet is a cereal of enormous importance with potentials in the agricultural systems and food security but it constitutes a neglected agrobiodiversity. Soil borne pathogenic fungi could be possible culprit to millet cultivation in southwestern Nigeria. Therefore, this study investigates the pathogenic effect of isolated Fusarium species from soil on millet seedlings under greenhouse conditions...

Maize (Zea mays L.) is susceptible to infection by Fusarium verticillioides through autoinfection and alloinfection, resulting in diseases and contamination of maize kernels with the fumonisin mycotoxins. Attempts at controlling this fungus are currently being done with biocontrol agents such as bacteria, and this includes bacterial endophytes, such as Bacillus mojavensis . In addition to produ...

Fusarium verticillioides causes ear rot and grain mycotoxins in maize (Zea mays L.), which are harmful to human and animal health. Breeding and growing less susceptible plant genotypes is one alternative to reduce these detrimental effects. A better understanding of the resistance mechanisms would facilitate the implementation of strategic molecular agriculture to breeding of resistant germplas...
