Design of DNA markers for intron length polymorphism analysis of α- and γ-tubulin genes in macromycetes
Abstract
Aim. Development of markers for determining Intron Length Polymorphism (ILP) of α- and γ-tubulin genes of macromycetes. Methods. Use of bioinformatic methods for search of gene loci encoding α- and γ-tubulins in macromycetes, analysis of exon-intron structure of genes, cladistic analysis, design of ILP markers, and verification of the designed primers using in silico PCR. Results. The exon-intron structure of α- and γ-tubulin genes in macromycetes was analyzed. Potential markers were designed to analyze the polymorphism of introns 1–3 of α-tubulins in Basidiomycetes, introns 2–4 of α-tubulins in Ascomycetes, and a set of six of potential markers for analyzing the polymorphism of introns 1, 2, 3, and 5 of γ-tubulins in Basidiomycetes. Conclusions. The feasibility of creating highly universal ILP markers based on α- and γ-tubulin gene sequences in macromycetes has been demonstrated. A series of potential ILP markers suitable for fungal genotyping has been proposed.
