2005 review

Photoactivated perylenequinone toxins in fungal pathogenesis of plants

[Review of ]. FEMS MICROBIOLOGY LETTERS, 252(2), 197–206.

By: M. Daub n, S. Herrero n & K. Chung*

author keywords: plant disease; non-specific toxin; active oxygen; pyridoxine; zinc cluster transcription factor
MeSH headings : Ascomycota / genetics; Ascomycota / metabolism; Light; Molecular Structure; Mycotoxins / chemistry; Mycotoxins / metabolism; Mycotoxins / toxicity; Perylene / analogs & derivatives; Perylene / chemistry; Perylene / metabolism; Perylene / toxicity; Photosensitizing Agents / toxicity; Plant Diseases / microbiology; Reactive Oxygen Species / metabolism
TL;DR: This review focuses on the well studied perylenequinone toxin, cercosporin, produced by species in the genus Cercospora, with the characterization of genes encoding a polyketide synthase and a major facilitator superfamily transporter representing the first and last steps of the biosynthetic pathway.

Cercosporin-deficient mutants by plasmid tagging in the asexual fungus Cercospora nicotianae

MOLECULAR GENETICS AND GENOMICS, 270(2), 103–113.

By: K. Chung n, M. Ehrenshaft n, D. Wetzel n & M. Daub n

author keywords: photosensitizer; plasmid rescue; active oxygen
MeSH headings : Amino Acid Sequence; Ascomycota / genetics; Ascomycota / metabolism; Ascomycota / pathogenicity; Base Sequence; Chromosome Mapping; DNA, Fungal / genetics; Gene Targeting; Genetic Vectors; Molecular Sequence Data; Multienzyme Complexes / genetics; Multienzyme Complexes / metabolism; Mutation; Mycotoxins / biosynthesis; Mycotoxins / genetics; Perylene / analogs & derivatives; Perylene / metabolism; Phenotype; Pigmentation; Plasmids / genetics; Sequence Homology, Amino Acid; Transformation, Genetic
TL;DR: The adaptation of plasmid insertion and restriction enzyme-mediated integration to produce cercosporin toxin-deficient mutants in the asexual phytopathogenic fungus Cercospora nicotianae is successfully adapted, providing the first molecular evidence that cercOSporin is synthesized via a polyketide pathway as previously hypothesized.

Expression of the cercosporin toxin resistance gene (CRG1) as a dicistronic mRNA in the filamentous fungus Cercospora nicotianae

CURRENT GENETICS, 43(6), 415–424.

By: K. Chung*, M. Daub n & M. Ehrenshaft n

author keywords: photosensitizer; singlet oxygen; toxin; transcription factor; uracil transporter; zinc finger DNA-binding domain
MeSH headings : Amino Acid Sequence; Ascomycota / drug effects; Ascomycota / genetics; Ascomycota / metabolism; Base Sequence; Drug Resistance / genetics; Fungal Proteins / biosynthesis; Fungal Proteins / genetics; Gene Expression; Genes; Genome, Fungal; Molecular Sequence Data; Nucleotide Transport Proteins / genetics; Nucleotide Transport Proteins / metabolism; Perylene / analogs & derivatives; Perylene / pharmacology; RNA, Fungal / metabolism; RNA, Messenger / metabolism; Reverse Transcriptase Polymerase Chain Reaction; Transcription Factors / genetics; Transcription Factors / metabolism; Transcription, Genetic
TL;DR: It is concluded that the 4.5-kb transcript is a dicistronic mRNA of both CRG1 and PUT1 in the fungus C. nicotianae, the first example of a d physicistronic mRNA identified in filamentous fungi. (via Semantic Scholar)

2002 journal article

Functional expression and cellular localization of cercosporin-resistance proteins fused with the GFP in Cercospora nicotianae

CURRENT GENETICS, 41(3), 159–167.

By: K. Chung n, M. Ehrenshaft n & M. Daub n

author keywords: photosensitizer; singlet oxygen; fungi; pyridoxine
MeSH headings : Ascomycota / drug effects; Ascomycota / genetics; Ascomycota / metabolism; Base Sequence; Blotting, Western; DNA Primers; Fungal Proteins / genetics; Fungal Proteins / metabolism; Green Fluorescent Proteins; Luminescent Proteins / metabolism; Microscopy, Confocal; Perylene / analogs & derivatives; Perylene / pharmacology; Recombinant Fusion Proteins / genetics; Recombinant Fusion Proteins / metabolism; Transformation, Genetic
TL;DR: Transformation of these constructs into strains mutant in these respective genes resulted in green-fluorescent transformants complemented for the mutant phenotype, a result inconsistent with microscopic observation and computer sequence analysis, which suggests that CRG1 is a membrane protein.
