“…However, this process was not reproducible during subsequent studies (Baldassari et al, 2008;Wang et al, 2016). Amorim et al (2017) conducted in vitro crossings with isolates of different mating types on various media and incubated plates at different conditions, but did not observe any sexual structures. The first successful and reproducible mating of P. citricarpa in culture was reported by Tran et al (2017), involving direct physical contact between two isolates of complementary mating types.…”

“…In Australia, Brazil, China and South Africa, MAT genotyping of populations revealed an almost equal mating type distribution, confirming the occurrence of sexual reproduction in these populations (Amorim et al ., ; Carstens et al ., ; Tran et al ., ; Wang et al ., ; Zhang et al ., ). Interestingly, in Florida in the USA, only one mating type has been identified (Carstens et al ., ; Wang et al ., ).…”

“…The heterothallic nature of P. citricarpa was recently confirmed through full sequence of target loci characterization, showing the presence of separated MAT1-1 or MAT1-2 idiomorphs (Amorim et al, 2017;Wang et al, 2016). Studies were performed during the last couple of decades with the aim of developing reliable methods to induce the sexual morph of P. citricarpa in vitro.…”

“…The occurrence of two opposite mating types genes ( MAT1‐1‐1 and MAT1‐2‐1 ) has been reported in P. citricarpa populations, confirming the heterothallic behaviour of the fungus and the necessity of crossing between opposite mating types in order to produce viable progeny (Amorim et al ., ; Wang et al ., , ).

Summary Several Phyllosticta species are known as pathogens of Citrus spp., and are responsible for various disease symptoms including leaf and fruit spots. One of the most important species is P. citricarpa, which causes a foliar and fruit disease called citrus black spot. The Phyllosticta species occurring on citrus can most effectively be distinguished from P. citricarpa by means of multilocus DNA sequence data. Recent studies also demonstrated P. citricarpa to be heterothallic, and reported successful mating in the laboratory. Since the domestication of citrus, different clones of P. citricarpa 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 Phyllosticta spp., demonstrating unknown aspects of these species, including their mating behaviour. Taxonomy Phyllosticta citricarpa (McAlpine) Aa, 1973. Kingdom Fungi, Phylum Ascomycota, Class Dothideomycetes, Order Botryosphaeriales, Family Phyllostictaceae, Genus Phyllosticta, Species citricarpa. Host range Confirmed on more than 12 Citrus species, Phyllosticta citricarpa has only been found on plant species in the Rutaceae. Disease symptoms P. citricarpa causes diverse symptoms such as hard spot, virulent spot, false melanose and freckle spot on fruit, and necrotic lesions on leaves and twigs.
