Phyllosticta citricarpa

Phyllosticta citricarpa provides a curated gene and genomic resource that leverages multilocus DNA sequence data and DOE JGI MycoCosm integration to support species discrimination, genomics, epidemiology, and disease-management research on the citrus pathogen Phyllosticta citricarpa.

Key Features:

• Curated gene database: A specialized gene-level repository focused on Phyllosticta citricarpa and closely related Phyllosticta species.
• Multilocus sequence data: Uses multilocus DNA sequence data to distinguish P. citricarpa from other Phyllosticta species affecting citrus.
• DOE JGI MycoCosm integration: Integrates genomic datasets via the DOE Joint Genome Institute MycoCosm portals.
• Genomic coverage: Provides access to genomic data from seven Phyllosticta species, including multiple P. citricarpa genomes (Phycitr1, Phycpc1).
• Mating system information: Captures evidence of the heterothallic nature of P. citricarpa, including laboratory mating study results.
• Taxonomic and disease context: Documents taxonomic placement (Kingdom Fungi; Phylum Ascomycota; Class Dothideomycetes; Order Botryosphaeriales; Family Phyllostictaceae; Genus Phyllosticta), host range (more than 12 Citrus species in Rutaceae), and citrus black spot symptoms (hard spots, virulent spots, false melanose, freckle spots, necrotic lesions).
• Literature synthesis: Compiles literature on identification, distribution, mating behavior, and emerging knowledge relevant to P. citricarpa biology.

Scientific Applications:

• Species identification: Discriminates P. citricarpa from other Phyllosticta species on citrus using multilocus sequence data.
• Genomics research: Enables genomic analyses and comparative studies using MycoCosm-linked genomes (including Phycitr1 and Phycpc1).
• Epidemiology and distribution studies: Supports investigations of geographic distribution and spread related to trade and domestication history.
• Disease management research: Informs development of management strategies for citrus black spot through genetic and genomic insights.
• Reproductive biology studies: Facilitates study of mating systems and heterothallism based on compiled mating evidence.

Methodology:

Employs multilocus DNA sequence analysis and integration of DOE JGI MycoCosm genomic datasets (seven Phyllosticta species, including P. citricarpa genomes Phycitr1 and Phycpc1) to support species discrimination and genomic investigation.
