Two new Ceratocystis species associated with mango disease in Brazil

Mangifera indica, a disease known as mango blight, murcha or seca da mangueira in Brazil, is caused by the canker wilt pathogen Ceratocystis fimbriata sensu lato. It is also closely associated with infestation by the non-native wood-boring beetle Hypocryphalus mangiferae (Coleoptera: Scolytinae). Th...

Description
Summary:Mangifera indica, a disease known as mango blight, murcha or seca da mangueira in Brazil, is caused by the canker wilt pathogen Ceratocystis fimbriata sensu lato. It is also closely associated with infestation by the non-native wood-boring beetle Hypocryphalus mangiferae (Coleoptera: Scolytinae). The aim of this study was to characterize Ceratocystis isolates obtained from diseased mango trees in Brazil. Identification was based on sequence data from ITS1+5.8S+ITS2 rDNA, part of the Beta-tubulin 1 gene, and part of the Transcription Elongation Factor 1-alpha gene. The Brazilian isolates grouped in two well defined and unique clades within C. fimbriata s. l. These were also distinct from C. manginecans, which causes a similar disease associated with H. mangiferae in Oman and Pakistan. Based on sequence comparisons and morphological characteristics, isolates representing the two phylogenetic clades are described as C. mangicola sp. nov. and C. mangivora sp. nov.
