Usnic acid is a unique polyketide produced by lichens. To characterize usnic acid
biosynthesis, the transcriptome of the usnic-acid-producing lichen-forming fungus
Nephromopsis pallescens was sequenced using Illumina NextSeq technology. Seven
complete non-reducing polyketide synthase genes and nine highly-reducing
polyketide synthase genes were obtained through transcriptome analysis. Gene
expression results obtained by qPCR and usnic acid detection with LCMS-IT-TOF
showed that Nppks7 is probably involved in usnic acid biosynthesis in N.
pallescens. Nppks7 is a non-reducing polyketide synthase with a MeT domain that
also possesses beta-ketoacyl-ACP synthase, acyl transferase, product template,
acyl carrier protein, C-methyltransferase, and Claisen cyclase domains.
Phylogenetic analysis shows that Nppks7and other polyketide synthases from
lichens form a unique monophyletic clade. Taken together, our data indicate that
Nppks7 is a novel PKS in N. pallescens that is likely involved in usnic acid
biosynthesis.
