Sexual Reproduction in Aspergillus flavus Sclerotia: Acquisition of Novel Alleles from Soil Populations and Uniparental Mitochondrial Inheritance

Horn, B. W., Gell, R. M., Singh, R., Sorensen, R. B., & Carbone, I. (2016, January 5). PLoS ONE, Vol. 11.

By: B. Horn *, R. Gell n, R. Singh n, R. Sorensen * & I. Carbone n 

MeSH headings : Alleles; Aspergillus flavus / genetics; Genes, Mitochondrial; Genetic Variation; Reproduction / genetics; Soil; Soil Microbiology
topics (OpenAlex): Plant Pathogens and Fungal Diseases; Mycotoxins in Agriculture and Food; Yeasts and Rust Fungi Studies
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.

Sexuality Generates Diversity in the Aflatoxin Gene Cluster: Evidence on a Global Scale

PLoS Pathogens, 9(8), e1003574.

topics (OpenAlex): Mycotoxins in Agriculture and Food; Plant Disease Resistance and Genetics; Plant Pathogens and Resistance
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. (via Semantic Scholar)

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
topics (OpenAlex): Mycotoxins in Agriculture and Food; Plant Pathogens and Fungal Diseases; Plant Disease Resistance and Genetics
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. (via Semantic Scholar)
