Sexual reproduction in Aspergillus flavus
Multiple, indehiscent ascocarps containing asci and ascospores formed within the pseudoparenchymatous matrix of stromata, which places the fungus in genus Petromyces.
Challenges facing the biological control strategy for eliminating aflatoxin contamination
Several challenges that the biocontrol strategy should address before this practice is introduced worldwide are described, including the need to better understand the diversity of A. flavus populations in the agricultural soil, the effects of climate change on both this diversity and on plant susceptibility.
Sexual reproduction in aflatoxin-producing Aspergillus nomius
Sexual reproduction was examined in the aflatoxin-producing fungus Aspergillus nomius. Crosses between sexually compatible strains resulted in the formation of multiple nonostiolate ascocarps within
Genomic sequence of the aflatoxigenic filamentous fungus Aspergillus nomius
This study provides a preliminary analysis of the A. nomius genome and finds that this genome sequence provides an additional evolutionary reference point for studying the genetics and biology of aflatoxigenic species production.
Recombination and lineage‐specific gene loss in the aflatoxin gene cluster of Aspergillus flavus
Aflatoxins produced by Aspergillus flavus are potent carcinogens that contaminate agricultural crops. Recent efforts to reduce aflatoxin concentrations in crops have focused on biological control
Unravelling the Diversity of the Cyclopiazonic Acid Family of Mycotoxins in Aspergillus flavus by UHPLC Triple-TOF HRMS
The screening and identification of several CPA-type alkaloids not previously found in A. flavus cultures are reported, and two metabolite discoveries, 11,12-dehydro α-CPA and 3-hydroxy-2-oxo CPA, have never been reported for any organism.
Draft Genome Sequence of an Aflatoxigenic Aspergillus Species, A. bombycis
The genome of the A. bombycis Type strain was sequenced and found it to be comparable in size and in numbers of predicted genes to other sequenced Aspergilli, and showed that this species is likely heterothallic (self-infertile) and contains a single MAT1-2 gene.
Fragmentation of an aflatoxin-like gene cluster in a forest pathogen.
This study focused on dothistromin genes, which are widely dispersed across one chromosome, to determine whether this unusual distributed arrangement evolved from an ancestral cluster, and suggests that cluster fragmentation may facilitate metabolic retooling and subsequent host adaptation of plant pathogens.
Enhanced diversity and aflatoxigenicity in interspecific hybrids of Aspergillus flavus and Aspergillus parasiticus
The results suggest that hybridization is an important diversifying force resulting in the genesis of novel toxin profiles in these agriculturally important fungi.
