Abstract
Abstract The angiosperm Melastomataceae family is one of the most abundant plant families worldwide and in the Brazilian cerrado, with significant environmental importance in regenerating degraded areas, especially those previously occupied by pastures. Recently, Chrysoporthe Gryzenhout & M. J. Wingf. species were reported in Brazil, causing canker, branch dieback, and mortality in native Melastomataceae. This leads to the demand for further investigation and understanding of these pathosystems. During field surveys, typical signs and symptoms associated with Chrysoporthe infection were found in Rhynchanthera grandiflora (Aubl.) D C. and Miconia theaezans (Bonpl.) Cogn. in southern Minas Gerais. Through phylogenetic analysis of the BT1 and BT2 fragments of the β‐tubulin gene and morphological characterization of the isolates obtained, it was possible to identify C. doradensis Gryzenh. & M. J. Wingf. occurring in R. grandiflora and C. puriensis M. E. S. Oliv., T. P. F. Soar. & M. A. Ferr. occurring in R. grandiflora and M. theaezans . Furthermore, pathogenicity assays confirmed the pathogenicity of both species to their hosts.
