As more such species are sequenced, he says, «everyone will be using these» genomes to find out which genes are responsible for particular functions, especially for plant pathogens such
as Fusarium, which causes ear rot in corn and puts out mycotoxins in animal feed.

Fusarium graminearum and other fungi that occurs mainly in grains such as wheat, barley, oats and maize, also known as vomitoxin.
Fusarium Head Blight (FHB) is a fungal disease that affects worldwide wheat production due to dramatic yield loss, and reduced grain quality from toxins that make harvests unsuitable for consumption.
I suppose I understand the decision —
Fusarium venenatum doesn't really have a ring to it — but it's not really the origin of the stuff that turns me off (although that doesn't help).
We now know the genome sequences of the banana and the fungi that
cause Fusarium wilt and Sigatoka.
Dr. Wenwei Xu, Texas A&M AgriLife Research corn breeder in Lubbock, examines a field of corn in the southern High Plains of Texas
for Fusarium fungus disease.
Causal agent: A number of different fungi and fungi - like organisms cause the symptoms of damping off, including: Alternaria species, Botrytis, and
Fusarium species.

with Fusarium oxysporum f. sp. niveum
Fusarium makes endocrine disrupting mycotoxins that are thousands of times stronger than normal female estrogen.

Fusarium mycotoxins and their dietary intake through beer consumption by the European population».
The first losses followed soon
after Fusarium wilt was reported in Panama and Costa Rica in the 1890s (the strains that cause disease on Gros Michel would later become known as race 1).
Over the past year, specific production research projects have concentrated on improving yields with better salinity and water management, plant breeding, avocado tree monitoring, pesticide resistance and
Fusarium dieback disease.
For her doctorate she bred pea plants to
resist fusarium wilt, a common pathogen that also affects tomatoes and potatoes.
In a world where more than one billion people do not have enough to eat, and our future food security is threatened by climate change and an ever - growing population, it is essential to improve the control of crop diseases
like fusarium ear blight around the globe.
Soybeans in the second vegetative stage infected with the pathogen
Fusarium proliferatum have underdeveloped root structures in comparison to healthy soybean seedlings.
In recent years there's been several reports of a fungus,
Fusarium solani, that has infected sea turtle eggs.
According to the polytechnic specialist, Trichoderma koningiopsis in some cases combats or prevents the growth of pathogens that attack cotton plant as P. omnívora,
Fusarium spp and Macrophomina phaseolina.
Currently the betting is on fungi of the
group Fusarium as the culprits.
The team found that simply replacing the baker's yeast mating receptor gene with similar genes from other pathogenic species — including Magnaporthe oryzae, which causes blast disease in rice, and
Fusarium graminearum, which causes blight disease in wheat and barley — allowed them to create a total of 10 new strains that can each detect a different disease.
PULLMAN, Wash. — Scientists at Washington State University and Kansas State University have isolated and cloned a gene that provides resistance to
Fusarium head blight, or wheat scab, a crippling disease that caused $ 7.6 billion in losses in U.S. wheat fields between 1993 and 2001.
This chili — and many like it — is plagued by a fungus
called Fusarium, which enters the peppers once bugs have poked holes in them and eats away the seeds.
To further aggravate the situation, Cavendish is also now under attack from a recently emerged strain
of Fusarium oxysporum, known as Tropical Race 4 (TR4).
In the cucurbit world, this means faster breeding for resistance to diseases such
as fusarium wilt or powdery mildew — that white film many gardeners might find killing their squash leaves, or enhancing production of carotenoids — the orange pigments associated with eye health, among other benefits.
In 1950, United Fruit (nowadays Chiquita) hired Robert H. Stover to devise management strategies
for Fusarium wilt, which by then was threatening the very existence of the export trade based on Gros Michel.
Association analysis for disease resistance to
Fusarium oxysporum in cape gooseberry (Physalis peruviana L)
When Cavendish cultivars exhibiting symptoms of
Fusarium wilt were first observed, the isolates were classified as race 4.
A fungal disease called
Fusarium wilt or Panama disease nearly wiped out the Gros Michel and brought the global banana export industry to the brink of collapse.
Fusarium wilt is responsible for the demise of the export trade based on Gros Michel.
Smith recognized that the isolated fungus was in the genus
Fusarium, and due to its Cuban source named it F. cubense.

Causal agent: Several fungi, such as Pythium, Rhizoctonia,
Fusarium, etc. are associated with this disorder.
An expert on
Fusarium fungus, David M. Geiser of the Pennsylvania State University Fusarium Research Center, told the FDA that calling the Fusarium fungus that is the basis of Quorn foods a mushroom is like «calling a rat a chicken because both are animals.»
For soilborne pathogens (Verticillium,
Fusarium, Pythium, Rhizoctonia, nematodes, etc.), a chemical, such as metham sodium (Vapam), may be added to the soil.
