The genes for polyketide synthases (PKSs), enzymes that assemble the carbon backbones
of many secondary metabolites, often cluster with other secondary pathway genes. We …

Lichens produce a diverse array of secondary metabolites that have shown various
biological activities. Of particular interest are the coupled phenolics that originate from …

The depside and depsidone series compounds of polyketide origin accumulate in the
cortical or medullary layers of lichen thalli. Despite the taxonomic and ecological …

Lichens are known to produce a variety of secondary metabolites including polyketides that
have diverse biological role (s). The biosynthesis of fungal polyketides is governed by type I …

Lichens and most ascomycete fungi produce polyketide secondary metabolites often with
valuable biological activities. Their biosynthesis is primarily governed by large iterative …

Lichen-forming fungi produce a variety of secondary metabolites including bioactive
polyketides. Advances in DNA and RNA sequencing have led to a growing database of new …

Fungi involved in lichen symbioses produce a large array of secondary metabolites that are
often diagnostic in the taxonomic delimitation of lichens. The most common lichen …

The ability to functionally express proteins in hosts is a precondition to an advanced
understanding of the biosynthetic pathways that are responsible for producing life's complex …

We characterize the transcript of a polyketide synthase gene (PKS) from the cultured
mycobiont of Xanthoria elegans (XePKS1) using SMART-rapid amplification of cDNA ends …

Lichen secondary metabolites (polyketides) are produced by the fungal partner, but the role
of algal carbohydrates in polyketide biosynthesis is not clear. This study examined whether …
