Phosphate Transporter Genes as Reliable Gene Markers for the Identification and Discrimination of Arbuscular Mycorrhizal Fungi in the Genus Glomus

An inorganic phosphate transporter gene sequence (852-bp section) allowed discrimination between 10 Glomus fungal species represented by 25 strains. It was particularly valuable in differentiating between morphologically similar species with nucleotide and amino acid sequence differences higher than 3%. This gene is proposed as a reliable barcode for the Glomeromycetes.
