a
PKS genes were determined using annotated and BLAST searches (NCBI) against each fungal genome.
b
The NR clade basal to NR clades I and II in the phylogenetic tree (Fig. 1).
c
PKS genes belonging to other reducing clades: D5, D6, and MSAS group (M). If more than one PKS gene is present in each of these clades, the number of PKS genes is in parentheses.
d
The PKS gene is clustered with the bacterial PKS group.
