Gene copy number polymorphisms in an arbuscular mycorrhizal fungal population

Appl Environ Microbiol. 2007 Jan;73(1):366-9. doi: 10.1128/AEM.01574-06. Epub 2006 Nov 3.

Abstract

Gene copy number polymorphism was studied in a population of the arbuscular mycorrhizal fungus Glomus intraradices by using a quantitative PCR approach on four different genomic regions. Variation in gene copy number was found for a pseudogene and for three ribosomal genes, providing conclusive evidence for a widespread occurrence of macromutational events in the population.
