Phyllosticta citricarpa and sister species of global importance to Citrus

摘要

Several species are known as pathogens of spp., and are responsible for various disease symptoms including leaf and fruit spots. One of the most important species is . which causes a foliar and fruit disease called citrus black spot. The species occurring on citrus can most effectively be distinguished from . by means of multilocus DNA sequence data. Recent studies also demonstrated . to be heterothallic, and reported successful mating in the laboratory. Since the domestication of citrus, different clones of have escaped Asia to other continents via trade routes, with obvious disease management consequences. This pathogen profile represents a comprehensive literature review of this pathogen and allied taxa associated with citrus, focusing on identification, distribution, genomics, epidemiology and disease management. This review also considers the knowledge emerging from seven genomes of spp., demonstrating unknown aspects of these species, including their mating behaviour.
