Expression analysis of putative candidate PKSs for production of the linear moiety of calbistrins. a Gene expression relative to actin for 3 putative PKS capable of performing a C-methylation in the P. decumbens wild type strain. b and c Gene expression changes in loss-of-function mutants of ∆calB and ∆calC, respectively, compared to the wild type strain. No complete absence of expression was detected in either of the deletion strains, suggesting that none of the PKSs are transcriptionally controlled by molecules from the calbistrin pathway
