2017 journal article
Global population structure and adaptive evolution of aflatoxin-producing fungi
Ecology and Evolution, 7(21), 9179–9191.
author keywords: Aspergillus; balancing selection; maximum likelihood; multilocus sequence typing; principal component analysis
TL;DR:
While clay soil and precipitation may influence species richness in Aspergillus section Flavi, other region‐specific environmental and genetic parameters must also be considered.

2016 journal article
Sexual Reproduction in Aspergillus flavus Sclerotia: Acquisition of Novel Alleles from Soil Populations and Uniparental Mitochondrial Inheritance
PLOS ONE, 11(1).
MeSH headings : Alleles; Aspergillus flavus / genetics; Genes, Mitochondrial; Genetic Variation; Reproduction / genetics; Soil; Soil Microbiology
TL;DR:
Sclerotia formed in crops are dispersed onto the soil surface at harvest and are predominantly produced by single strains of one mating type and conidia from both strains functioned as female and male, respectively, indicating A. flavus is hermaphroditic, although the degree of fertility depended upon the parental sources.

Sexual recombination in Aspergillus tubingensis
MYCOLOGIA, 107(2), 307–312.
author keywords: Aspergillus niger; mating type; multilocus sequence typing; sexual reproduction
MeSH headings : Aspergillus / genetics; Aspergillus / physiology; Fungal Proteins / genetics; Fungal Proteins / metabolism; Genes, Mating Type, Fungal; Haplotypes; Recombination, Genetic
TL;DR:
Recombination associated with sexual reproduction in A. tubingensis provides a new option for the genetic improvement of industrial strains for enzyme and organic acid production.

2013 journal article
Sexuality Generates Diversity in the Aflatoxin Gene Cluster: Evidence on a Global Scale
PLoS Pathogens, 9(8), e1003574.
Ed(s): B. McDonald
MeSH headings : Aflatoxins / biosynthesis; Aflatoxins / genetics; Aspergillus flavus / genetics; Aspergillus flavus / metabolism; Fungal Proteins / genetics; Fungal Proteins / metabolism; Genes, Fungal / physiology; Multigene Family / physiology; Repressor Proteins / genetics; Repressor Proteins / metabolism; Species Specificity
TL;DR:
It is shown that the reproductive nature of the population (more sexual versus more asexual) is predictive of aflatoxin chemotype diversity in these agriculturally important fungi.

2011 journal article
Effect of sexual recombination on population diversity in aflatoxin production by Aspergillus flavus and evidence for cryptic heterokaryosis
MOLECULAR ECOLOGY, 21(6), 1453–1476.
author keywords: array comparative genome hybridization; biological control; heritability; multilocus sequence typing; non-Mendelian segregation; vegetative compatibility group
MeSH headings : Aflatoxins / biosynthesis; Aspergillus flavus / genetics; Aspergillus flavus / metabolism; Comparative Genomic Hybridization; Fungal Proteins / genetics; Genes, Mating Type, Fungal / genetics; Genetic Variation; Karyotyping; Molecular Sequence Data; Multigene Family; Recombination, Genetic; Sequence Analysis, DNA
TL;DR:
Results from experimental matings indicate that sexual recombination is driving genetic and functional hyperdiversity in A. flavus, and have significant implications for managing AF contamination of crops and for improving biocontrol strategies using nonaflatoxigenic strains of A. Flavus.
