“…Já em inoculações em ramos e frutos de mangueira, esta espécie produziu lesões que foram significativamente diferentes do controle (37). Esta espécie foi primeiramente descrita por Pavlic et al (32), causando morte em ramos de Adansonia gibbosa F. Muell. e como endofítica em Acacia synchronica, Eucaliptus sp.…”

Espécies de Botryosphaeriaceae são importantes patógenos em diversas plantas lenhosas e não lenhosas, causando diferentes tipos de sintomas. Espécies desta família são usualmente consideradas patógenos fracos, causando doenças apenas quando estas plantas se encontram sob algum tipo de estresse como seca, temperaturas baixas ou elevadas, deficiência nutricional e danos causados por outros patógenos ou pragas. No entanto, pouco se conhece sobre a ocorrência e diversidade de espécies de Botryosphaeriaceae em plantas nativas do bioma Caatinga, localizado no Semiárido, e sobre a presença de fungos endofíticos nessas espécies, e muito menos sobre a sua importância como patógenos. O objetivo do presente estudo foi avaliar a patogenicidade de 74 isolados representando Espécies de Botryosphaeriaceae (Dothideomycetes) têm distribuição mundial, sendo encontradas em todas as regiões geográficas, incluindo áreas de clima tropical, temperado e até em ambiente marinho, com exceção das regiões polares (2,34,35,38). Já foram relatadas infectando plantas do grupo das monocotiledôneas, dicotiledôneas e gimnospermas, e até liquens (1). Seus hospedeiros incluem uma diversidade de plantas de importância agronômica, florestal e ornamental (1, 8). Entre as doenças causadas por espécies de Botryosphaeriaceae estão podridão de frutos, manchas foliares, tombamento e podridão de colo em mudas, cancros, secas em brotos e mudas, gomose, seca descendente, vassoura-de-bruxa e morte de árvores (41).Espécies de Botryosphaeriaceae são frequentemente descritas como oportunistas ou patógenos latentes, os quais apresentam longo período de latência antes que algum fator como, por exemplo, estresse hídrico faça com que eles se tornem patogênicos, causando, frequentemente, cancros em seus hospedeiros (6,28,42,45). Essas espécies são bem conhecidas como endofíticas em uma variedade de plantas arbóreas. Entre as principais famílias botânicas já estudadas incluem-se Moraceae, Myrtaceae, Proteacea, Leguminosae, Pinaceae, Vitaceae e Anacardiaceae (6, 8, 9,15,16,24,27,29,42,43,44).No Ceará, o bioma Caatinga cobre uma área de 126.926 km 2 , ABSTRACTSpecies of the Botryosphaeriaceae are important pathogens in several woody and non-woody plants, causing different types of symptoms. Species of this family are usually regarded as weak pathogens, only causing diseases when plants are under some type of stress such as drought, hot or cold weather, poor nutrition and damage caused by other pathogens or pests. However, little is known about the occurrence and diversity of Botryosphaeriaceae species in native plants of the biome Caatinga, located in the Brazilian Semi-Arid Region, and about the presence of endophytic fungi in these species; even less is known about their importance as pathogens. The aim of the present study was to assess the pathogenicity of 74 isolates representing the species Botyosphaeria mamane, Pseudofusicoccum adansoniae, P. stromaticum, the complex Neofusicoccum parvum/ribis, Lasiodiplodia gonubiensis and L.theobromae, identified for the first ...

“…However, its common occurrence on both introduced and native plants has led to suggestions that N. parvum might be part of the indigenous fungal flora of South Africa (Pavlic et al 2007(Pavlic et al , 2008(Pavlic et al , 2009a. In contrast, L. theobromae, which has a wide host range and has been reported on native and introduced hosts on many continents, may have been introduced to Africa.…”

Species in the Botryosphaeriaceae represent some of the most important fungal pathogens of woody plants. Although these fungi have been relatively well studied on economically important crops, hardly anything is known regarding their taxonomy or ecology on native or non-commercial tree species. The aim of this study was to compare the diversity and distribution of the Botryosphaeriaceae on Terminalia catappa, a tropical tree of Asian origin planted as an ornamental in Cameroon, Madagascar and South Africa. A total of 83 trees were sampled, yielding 79 Botryosphaeriaceae isolates. Isolates were initially grouped based on morphology of cultures and conidia. Representatives of the different morphological groups were then further characterised using sequence data for the ITS, tef 1-alpha, rpb2, BOTF15 and beta-tubulin gene regions. Five species of the Botryosphaeriaceae were identified, including Neofusicoccum parvum, N. batangarum sp. nov., Lasiodiplodia pseudotheobromae, L. theobromae and L. mahajangana sp. nov. Lasiodiplodia pseudotheobromae and L. theobromae, were the most commonly isolated species (62%), and were found at all the sites. Neofusicoccum parvum and N. batangarum were found in South Africa and Cameroon, respectively, whereas L. mahajangana was found only in Madagascar. Greenhouse inoculation trials performed on young T. catappa trees showed variation among isolates tested, with L. pseudotheobromae being the most pathogenic. The Botryosphaeriaceae infecting T. catappa appear to be dominated by generalist species that also occur on various other hosts in tropical and sub-tropical climates.

Members of the Botryosphaeriaceae, in particular Lasiodiplodia theobromae, Neofusicoccum parvum, Neofusicoccum mangiferae and Botryosphaeria dothidea, commonly cause stem cankers, dieback and stem end rot of mangoes worldwide. In the current study, eight taxa of Botryosphaeriaceae were identified as canker-associated fungi, pathogens, potential pathogens or endophytes of mangoes in the Kimberley, Australia. These include Neoscytalidium novaehollandiae, Neoscytalidium dimidiatum, Pseudofusicoccum adansoniae, P. ardesiacum, P.kimberleyense, Lasiodiplodia sp. 1, Lasiodiplodia iraniensis and Lasiodiplodia pseudotheobromae. The pathogenicity of a selection of these species toward fruit and branches was tested. All were pathogenic to mango in comparison to the control, with Lasiodiplodia spp.being the most pathogenic. It appears that either geographic isolation or the unique growing conditions in the Kimberley may have provided an effective barrier to the acquisition or establishment of known botryosphaeriaceous pathogens. Wounds caused by mechanical pruning may provide an entry point for infection, whilst severe pruning may increase plant stress.
