Fig. 4. Neighbor-joining phylogenetic analysis of β-tubulin gene sequences of Talaromyces purpurogenus KNU14-10 and Talaromyces trachyspermus KNU14-24-1 obtained from crop field soil in Korea. A phylogenetic tree was constructed using the MEGA ver. 6 program. Sequences obtained in the study are shown in boldface. The mark (T) indicates type strain. Numerical values (> 50) on branches are the bootstrap values as percentage of bootstrap replication from a 1,000 replicate analysis. Thermoascus crustaceus was used as an outgroup. Scale bar represents the number of substitutions per site.
