Genetic Characteristics and Metabolic Interactions between Pseudocercospora fijiensis and Banana: Progress toward Controlling Black Sigatoka

[Review of ]. PLANTS-BASEL, 11(7).

By: R. Noar n, E. Thomas n  & M. Daub n

author keywords: black Sigatoka; cell wall; dispensable chromosomes; Dothideomycetes; effectors; genomics; host resistance; pathogenicity; secondary metabolism
TL;DR: P. fijiensis has been identified as having high evolutionary potential, given its large genome size, ability to reproduce both sexually and asexually, and long-distance spore dispersal, and multiple control measures are needed for the sustainable control of black Sigatoka disease.

Ed(s): R. Wilson

MeSH headings : Ascomycota / genetics; Ascomycota / pathogenicity; Fungal Proteins / genetics; Mycoses / microbiology; Plant Diseases / microbiology; Polyketide Synthases / genetics
TL;DR: An important role for the PKS10-2 polyketide pathway in pathogenicity of Pseudocercospora fijiensis is supported, and a possible role for this pathway in disease development by other PseudOCercOSpora species is suggested. (via Semantic Scholar)

Engineering Cercospora disease resistance via expression of Cercospora nicotianae cercosporin-resistance genes and silencing of cercosporin production in tobacco

PLOS ONE, 15(3), e0230362.

By: E. Thomas n , S. Herrero n, H. Eng n, N. Gomaa n, J. Gillikin n, R. Noar n, A. Beseli n, M. Daub n

Ed(s): R. Wilson

MeSH headings : Ascomycota / drug effects; Ascomycota / genetics; Disease Resistance / drug effects; Disease Resistance / genetics; Drug Resistance, Fungal / drug effects; Drug Resistance, Fungal / genetics; Gene Expression Regulation, Fungal / drug effects; Gene Silencing / drug effects; Genes, Fungal; Genetic Engineering; Perylene / analogs & derivatives; Perylene / pharmacology; Plants, Genetically Modified; Tobacco / microbiology; Transformation, Genetic; Transgenes
TL;DR: It is concluded that expression of fungal cercosporin autoresistance genes as well as silencing of the cercsporin pathway are both effective strategies for engineering resistance to Cercospora diseases where cercOSporin plays a critical role. (via Semantic Scholar)

A novel polyketide synthase gene cluster in the plant pathogenic fungus Pseudocercospora fijiensis

PLOS ONE, 14(2), e0212229.

By: R. Noar n, E. Thomas n  & M. Daub n

Ed(s): O. Lespinet

MeSH headings : Ascomycota / enzymology; Ascomycota / genetics; Fungal Proteins / biosynthesis; Fungal Proteins / genetics; Gene Expression Regulation, Enzymologic / physiology; Gene Expression Regulation, Fungal / physiology; Multigene Family; Musa / microbiology; Plant Diseases / microbiology; Polyketide Synthases / biosynthesis; Polyketide Synthases / genetics
TL;DR: Genome analysis of the P. fijiensis PKS8-1 gene identified it as part of a gene cluster including genes encoding two transcription factors, a regulatory protein, a glyoxylase/beta-lactamase-like protein, an MFS transporter, a cytochrome P450, two aldo/keto reductases, a dehydrogenase, and a decarboxylase, which supports a role for this pathway in disease.

A polyketide synthase gene cluster associated with the sexual reproductive cycle of the banana pathogen, Pseudocercospora fijiensis

PLOS ONE, 14(7), e0220319.

By: R. Noar n, E. Thomas n , D. Xie n , M. Carter  n, D. Ma n & M. Daub n

Ed(s): O. Lespinet

MeSH headings : Ascomycota / enzymology; Ascomycota / genetics; Ascomycota / pathogenicity; Ascomycota / physiology; Fungal Proteins / genetics; Multigene Family; Musa / microbiology; Neurospora crassa / enzymology; Neurospora crassa / genetics; Phylogeny; Plant Diseases / genetics; Plant Diseases / microbiology; Plant Leaves / microbiology; Polyketide Synthases / genetics; Reproduction / genetics; Sequence Homology; Sordariales / enzymology; Sordariales / genetics
