Generally, excessive moisture conditions and high temperatures of storage grains and legumes increase the occurrence of A. flavus aflatoxin production. (wikipedia.org)
The results demonstrated that aflatoxin production in A. flavus was completely blocked after cycloleucine treatment. (bvsalud.org)
Aspergillosis4
A. flavus is also an opportunistic human and animal pathogen, causing aspergillosis in immunocompromised individuals. (wikipedia.org)
In mammals, the pathogen can cause liver cancer through consumption of contaminated feed or aspergillosis through invasive growth. (wikipedia.org)
This fungus is also the second leading cause of human invasive aspergillosis, after Aspergillus fumigatus, a disease that is particularly prevalent in immunocompromised individuals. (bvsalud.org)
Powdery1
Aspergillus flavus colonies are commonly powdery masses of yellowish-green spores on the upper surface and reddish-gold on the lower surface. (wikipedia.org)
Fungus5
Aspergillus flavus is a saprotrophic and pathogenic fungus with a cosmopolitan distribution. (wikipedia.org)
botrytis cinerea, the gray mold fungus, is an important plant pathogen. (liverpool.ac.uk)
in the filamentous fungus aspergillus nidulans, however, little is known about the molecular genetic mechanisms of vacuolar biogenesis and function. (liverpool.ac.uk)
the filamentous fungus aspergillus oryzae is a well-known expression host used to express homologous and heterologous proteins in a number of industrial applications. (liverpool.ac.uk)
Aspergillus flavus is a mycotoxigenic fungus that contaminates many important agricultural crops with aflatoxin B1, the most toxic and carcinogenic natural compound. (bvsalud.org)
Sporulation2
A. flavus has the potential to infect seedlings by sporulation on injured seeds. (wikipedia.org)
the ß-importin kap8 (pse1/kap121) is required for nuclear import of the cellulase transcriptional regulator xyr1, asexual sporulation and stress resistance in trichoderma reesei. (liverpool.ac.uk)
Crops2
Aspergillus flavus is found globally as a saprophyte in soils and causes disease on many important agriculture crops. (wikipedia.org)
ENVIRONMENTAL IMPLICATION: Aflatoxins, highly carcinogenic secondary metabolites produced by Aspergillus flavus, frequently contaminate crops such as peanut, corn, wheat and sesame leading to irreversible loss in the quality and yield of agricultural products and posing serious threats to food safety. (bvsalud.org)
Secondary4
There is a secondary inoculum for A. flavus, which is conidia on leaf parts and leaves. (wikipedia.org)
field populations are characterized by variability with regard to morphology, the mode of reproduction (conidiation or sclerotia formation), the spectrum of secondary metabolites (sm), and virulence. (liverpool.ac.uk)
Aspergillus flavus and its toxic aflatoxins secondary metabolites contaminate food and grains, posing a severe threat to human health and leading to liver cancer. (bvsalud.org)
More comprehensive analyses of secondary metabolite evolution will be possible by working with more complete and accurate genomes of taxonomically diverse Aspergillus species. (bvsalud.org)
Morphology1
Aspergillus flavus is complex in its morphology and can be classified into two groups based on the size of sclerotia produced. (wikipedia.org)
Infections2
A. flavus infections can occur while hosts are still in the field (preharvest), but often show no symptoms (dormancy) until postharvest storage or transport. (wikipedia.org)
Azole drugs are considered the most effective compounds in controlling Aspergillus infections both in clinical and agricultural settings. (bvsalud.org)
Gene3
construction of a shuttle vector for heterologous expression of a novel fungal α-amylase gene in aspergillus oryzae. (liverpool.ac.uk)
pasop carries a selectable marker, pyrg, derived from aspergillus nidulans, and a strong promoter and a terminator of the amyb gene derived from a. oryzae. (liverpool.ac.uk)
Although the aflatoxin biosynthesis gene cluster of A. pseudotamarii is conserved with Aspergillus flavus, the cluster has an inverted orientation relative to the telomere and occurs on a different chromosome. (bvsalud.org)
Resistance2
negative regulation of the vacuole-mediated resistance to k(+) stress by a novel c2h2 zinc finger transcription factor encoded by asla in aspergillus nidulans. (liverpool.ac.uk)
The pathogen induces hyperplastic growth of epidermal cells of potato tuber resulting in the formation of warts or galls. (biologydiscussion.com)
Frequently1
Its specific name flavus derives from the Latin meaning yellow, a reference to the frequently observed colour of the spores. (wikipedia.org)
Field2
In grains, the pathogen can invade seed embryos and cause infection, which decreases germination and can lead to infected seeds planted in the field. (wikipedia.org)
The incidence of A. flavus infection increases in the presence of insects and any type of stress on the host in the field as a result of damage. (wikipedia.org)
Sexual2
Recently, Petromyces was identified as the sexual reproductive stage of A. flavus, where the ascospores develop within sclerotia. (wikipedia.org)
Synchytrium endobioticum possesses both a sexual and asexual phase in its life cycle. (biologydiscussion.com)
Complex1
natural variation in bcvel1 encoding the ortholog of aspergillus nidulans vea, a member of the velvet complex, was previously shown to affect light-dependent differentiation, the formation of oxalic acid (oa), and virulence. (liverpool.ac.uk)
Reproduction1
The conidiospores are asexual spores produced by A. flavus during reproduction. (wikipedia.org)
Primary1
These conidia are said to be the primary inoculum for A. flavus. (wikipedia.org)
Completely1
strains expressing the myob(g843d) allele produce mainly aberrant septa at 30 °c and are completely aseptate at temperatures above 37 °c. conidium formation is greatly reduced at 30 °c and progressively impaired with increasing temperature. (liverpool.ac.uk)
Opportunistic2
A. flavus is also an opportunistic human and animal pathogen, causing aspergillosis in immunocompromised individuals. (wikipedia.org)
Aspergillus flavus is an opportunistic mycotoxigenic fungus that causes invasive and noninvasive aspergillosis, diseases with high rates of mortality in immunocompromised individuals. (bvsalud.org)
Mycotoxins1
IMPORTANCE Fungal pathogens cause human disease and threaten global food security by contaminating crops with toxins (mycotoxins). (bvsalud.org)
Strain2
The L strain also has a more acidic homoeostatic point and produces less sclerotia than the S strain under more limiting conditions. (wikipedia.org)
We found that an aflatoxin-producing A. flavus strain adapted to voriconazole exposure at levels above the MIC through whole or segmental aneuploidy of specific chromosomes. (bvsalud.org)
Typically1
Unique to the S strains is the production of aflatoxin G1 and G2 which typically are not produced by A. flavus. (wikipedia.org)
