Mango (Mangifera indica) is a major tropical fruit species cultivated in Brazil. The objective of this study was to identify species of Lasiodiplodia associated with dieback and stem-end rot of mango in the semi-arid region of Northeastern Brazil, and compare the species in relation to mycelial growth, pathogenicity and virulence. A total of 120 isolates of(More)
Members of the Botryosphaeriaceae are well known fungi associated with dieback, canker and fruit rot on various hosts worldwide, including mango. The aim of this study was identify a large collection of Botryosphaeriaceae species associated with dieback and stem-end rot of mango in the semi-arid region of Northeastern Brazil, and compare the species in(More)
Colletotrichum species are the most important and widespread form of decay affecting mango fruit worldwide. In this study, Colletotrichum species associated with fruit anthracnose isolated from mango in northeastern Brazil were subject to molecular and morphological analyses. The partial sequences of the glyceraldehyde-3-phosphate dehydrogenase gene of 143(More)
Two new genera, Neophaeosphaeria and Phaeosphaeriopsis, are described to accommodate species of Paraphaeosphaeria that are not congeneric based on morphological characters and results of 18S rDNA sequence analyses. Paraphaeosphaeria s. str. is restricted to species with two-septate ascospores and anamorphs that produce non-septate, smooth, pale brown(More)
Endophytic species of Colletotrichum associated with Mangifera indica (mango) are poorly understood. In this study, Colletotrichum species were isolated from mango in Pernambuco State, Brazil. There were significant differences in isolation frequencies of Colletotrichum species among sites and plant tissues. Mature leaf blades were colonized by most(More)
This study aims to identify and characterize species of Lasiodiplodia associated with stem-end rot of papaya in six different populations in the Northeast of Brazil. Fungal identifications were made using a combination of morphology together with a phylogenetic analysis based on partial translation elongation factor 1-α sequence (EF-1α) and internal(More)
Anthracnose, caused by various species of Colletotrichum, is the most common disease affecting mango trees in northeastern Brazil. This disease limits production and drastically reduces fruit quality, which directly affects the export of the fruit. In this study, we investigated the virulence of five species of Colletotrichum prevalent in the orchards of(More)
