| The aim of this work was to study the endophytic fungi associated with the tissues of Ipomoea carnea, a common invasive plant of India. A total of 69 isolates belonging to ten taxa comprising 1.45% Zygomycetes, 10.14% Coelomycetes, 62.32% Hypomycetes, 18.84% sterile mycelia and 7.25% unidentified species were obtained. Species of Curvularia, Aspergillus, Fusarium, Colletotrichum and sterile fungus were isolated as dominant endophytes. Colonization frequency of Curvularia (7.25%) was highest which was isolated from all the tissues. The samples collected during the monsoon harbored more endophytes and showed higher species richness than the samples obtained in summer season. Of the total isolates, 15 isolates (21.74%) displayed antimicrobial activity,... |

| A ocorrência da Mancha de Curvulária normalmente está associada às condições de manejo da sementeira e do viveiro, cuja influência é determinante e crítica para o aparecimento da doença, já nessas fases. A falta de inspeção periódica para eliminação de possíveis focos ocasionais de doenças e pragas, a falta ou excesso de irrigação, realização de adubação inadequada, por ocasião da preparação das sementeiras ou do substrato para as mudas, bem como falta de aclimatação das mudas ao sol e boa aeração, constituem-se em fatores essenciais ao bom crescimento das plantas, tanto em condições de viveiro, como em plantio definitivo. |

| Exserohilum includes a number of plant pathogenic, saprobic and clinically relevant fungi. Some of these species are of great importance in human activities, but the genus has never been revised in a phylogenetic framework. In this study, we revise Exserohilum based on available ex-type cultures from worldwide collections, observation of the holotypes and/or protologues, and additional isolates from diverse substrates and geographical origins. Based on nine nuclear loci, i.e., ITS, LSU, act, tub2, cam, gapdh, his, tef1 and rpb2, as well as phenotypic data, the genus and species boundaries are assessed for Exserohilum. Three species, i.e., E. novae-zelandiae, E. paspali and E. sorghicola, are excluded from the genus and reallocated in Sporidesmiella and... |

| The fungal genus Curvularia includes numerous plant pathogens and some emerging opportunistic pathogens of humans. In a previous study we used morphology and sequences of the nuclear ribosomal internal transcribed spacer region (ITS) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene to identify species within a set of 99 clinical Curvularia isolates from the USA. Seventy-two isolates could be identified while the remaining 27 isolates belonged in three unclassified clades that were tentatively labelled Curvularia sp. I, II and III. In the present study, we further assess the taxonomic placement of these isolates using sequences of ITS, gpd, the large subunit rDNA, and the second largest subunit of RNA polymerase II. DNA sequence comparisons with a... |

| En el presente trabajo se identificaron mediante técnicas tradicionales (cámaras húmedas, aislamientos en medios de cultivos específicos y cortes de cuerpos fructíferos) hongos que afectaban hojas de Capsicum chinense Jacq., Heliconia sp., Veitichia merrillii Becc., Polianthes tuberosa L., Jatropha curcas L. y Thevethia ahouai A. DC. A partir de muestras foliares de plantas enfermas se obtuvieron ocho cepas de los géneros Curvularia, Alternaria y Helminthosporium. Para el control de estos patógenos se evaluó la efectividad de los fungicidas sistémicos Azoxystrobin, Benomyl, Fosetil aluminio (Fosetil Al), Tiabendazole, Imazalil y Procloraz con un testigo sin aplicación de fungicida. El fungicida que indujo el mayor porcentaje (100%) de inhibición para los... |
