Taxonomic position of Korean strains of Aspergillus section Fumigati based on partial β-tubulin phylogeny. Partial β-tubulin gene (primers bt2a and bt2b) sequences were first analyzed using the Tamura-Nei parameter distance calculation model with gamma-distributed substitution rates, which was then used to construct the Neighbor-Joining tree with MEGA version 3.1. The numbers above or below the nodes represent bootstrap values of > 70% (out of 1,000 bootstrap replications). KACC strains were isolated from arable soil in Korea.
