Phylogenetic analysis of isolate IR-3-3. A neighbor joining tree was constructed with 22 strains (21 strains of P. citrinum obtained through Blast, and one clone strain IR-3-3). A. fumigatus was used as outgroup for rooting the tree. Fungal isolate IR-3-3 formed 95% bootstrap support for monoclade formed by all members of P. citrinum, after 1000 bootstrap replications, strongly supporting its identification as a new strain of P. citrinum.
