Phylogenetic and domain analysis of polyketide synthases (PKS) in C. cassiicola HGCC and other fungi. a A maximum likelihood tree of ketoacyl CoA synthase (KS) domain sequences of PKS in selected fungi. b Domain analysis of these PKSs using the SBSPKS database. Domain definitions were as follows: KS, ketoacyl CoA synthase; AT, acyltransferase domain; DH, dehydratase domain; ER, enoyl reductase domain; KR, ketoreductase domain; ACP, acyl carrier protein domain. c Toxins and melanin related to reported PKS in other fungi, the accession No. of which are shown in the “Methods” section. ^*g13578 and ^*g7009 are specific in CCP when compared to HGCC
