“…SER is caused by a range of species of the Botryosphaeriaceae including N. parvum, N. mangiferae, B. dothidea and L. theobromae (Slippers et al 2005;Johnson 2008). These pathogens may establish asymptomatically in the field, with disease expression linked to stress or ripening fruit.…”

“…However, the telomorphs of many species of Botryosphaeriaceae are rarely encountered and the anamorphs often have overlapping morphological characteristics and share niches. This has led to confusion and misidentification of species, necessitating the use of molecular phylogenetic methods to confirm species level identification (Smith and Stanosz 2001;Burgess et al 2005;Slippers et al 2005;Burgess et al 2006a;Crous et al 2006).…”

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.

RESUMO:A mangicultura praticada no Submédio do Vale do São Francisco é considerada um dos principais destaques no comércio externo do País. Dentre as diversas variedades cultivadas, a Tommy Atkins é a que representa a maior parte das exportações. Entretanto, a magnitude das perdas por podridões pós--colheita, causadas por fungos Botryosphaeriaceae, é sempre uma grande preocupação para exportadores e importadores da fruta. A busca por métodos de controle mais eficazes e limpos é uma tendência mundial. Nesse sentido, o objetivo deste trabalho foi avaliar a reação de frutos, de 47 acessos de mangueiras, quanto à resistência aos fungos Fusicoccum aesculis e Neofusicoccum parvum. As inoculações foram realizadas mediante deposição de disco do meio de cultura batata-dextrose-ágar (BDA), contendo estruturas do pató-geno sobre duas posições opostas na região equatorial da manga, mantido, posteriormente, por 24 horas em câmara úmida. Foram realizadas medições das lesões até o sétimo dia, com uma régua milimetrada. Com os registros dos crescimentos das lesões, foram calculadas as taxas diárias de crescimento da lesão (TDCL's) para cada acesso. As maiores TDCLs foram observadas nos acessos 'Roxa' e 'Lita', quando inoculados com F. aesculis, e nos acessos 'Roxa', 'Ruby', 'Papo de peru', 'CPAC 22/93', 'Pingo-de-ouro', 'Pêssego' e 'M13269', quando inoculados com N. parvum. Os acessos 'Nego-não-chupa', 'Manga-d'água', 'Juazeiro VI', 'Juazeiro VII' e 'Favo-de-mel' foram os que apresentaram, concomitantemente, as menores TDCLs para ambos os patógenos e diferenças significativas em relação aos demais acessos. Termos para indexação: Podridão peduncular, Botryosphaeriaceae, Mangifera indica. RESISTANCE AVALIATION OF 47 MANGO GERMPLASM TO THE FUNGIFusicoccum aesculis AND Neofusicoccum parvum ABSTRACT -The production of mango in the San Francisco Valley lower basin is considered one of the highlights in the export of the fruit by the country. Fruits of the cultivar Tommy Atkins are the most exported. However, the magnitude of losses due to post-harvest rots caused by fungi Botryosphaeriaceae is always a major concern for the exporter and importer of fruit. The search for control methods more effective and clean is a worldwide trend. The objective of this study was to evaluate the reaction of the fruits of 47 mango genotypes, for resistance to fungi Fusicoccum aesculis and Neofusicoccum parvum. The inoculations were performed by means of deposition culture medium discs potato-dextrose-agar (PDA) containing the pathogen structures on two positions perpendicular to the mango, and then maintained for 24 hours in a humid chamber.

“…Anamorph morphology, usually adopted to identify species of Botryosphaeriaceae, is also unable to resolve closely related species (Denman et al 2000;Slippers et al 2004). Comparisons of DNA sequences for various gene regions have led to re-evaluation of the Botryosphaeriaceae, and numerous new genera and species have been proposed (Crous et al 2006;Denman et al 2000;Pavlic et al 2009;Phillips et al 2005Phillips et al , 2008Slippers et al 2004Slippers et al , 2005a.…”

Diversity and pathogenicity of Botryosphaeriaceae on declining Ostrya carpinifolia in Slovenia and Italy following extreme weather conditions

et al. 2010

Unusual and extensive dieback of European hop hornbeam (Ostrya carpinifolia) has been observed in western Slovenia and northern Italy in recent years, when extreme drought and higher temperatures were recorded. A preliminary study identified Botryosphaeria dothidea as a potential causative agent of the dieback. Further characterization of intra-and interspecies diversity of Botryosphaeriaceae collected from O. carpinifolia and other tree species in the affected area was achieved based on anamorph morphology, sequence data from the ITS rDNA and EF1-α, PCR-RFLP analysis and AFLP profiles. The majority of the isolates analyzed were identified as B. dothidea, and in vitro pathogenicity tests re-confirmed the fungus to be an important cause of the disease. Insight into the B. dothidea population, diversity based on AFLP markers indicates that the dieback observed in O. carpinifolia is probably associated with a heterogenous population of B. dothidea, which emerged from a latent state in response to changed climate conditions. Isolates with Dothiorella-like conidia were also identified during the survey, but these were collected more rarely and appear to represent undescribed species. Isolates from Dothiorella genus expressed low pathogenicity in pathogenicity tests and proved no impact on the pathogenic ability of B. dothidea.
