| 1 | Five Colletotrichum species are responsible for mango anthracnose in northeastern Brazil显示文摘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 Colletotrichum isolates was amplified,as an initial measure of genetic diversity.A subset of 47 isolates,selected to represent the range of genetic diversity and geographic origin,were further sequenced using the partial actin,β-tubulin,calmodulin,glutamine synthetase genes and rDNA-ITS region.The multilocus sequence analysis,together with a critical examination of the phenotypic characters,revealed four previously described species(Colletotrichum asianum,Colletotrichum fructicola,Colletotrichum tropicale and Colletotrichum karstii)and one new species.The new species is introduced as Colletotrichum dianesei and formally described,illustrated and compared with similar taxa.Only C.asianum and C.karstii have previously been reported from mango,while the other species represent the first report associated with the mango fruits worldwide.All species are reported for the first time associated with the mango fruits in Brazil. | Nelson B.Lima Marcus Vinicius de A.Batista Marcos A.De Morais Jr Maria A.G.Barbosa Sami J.Michereff Kevin D.Hyde Marcos P.S.Câmara | 2013 | Fungal Diversity2013，，4： | 7 |
| 2 | Species of Lasiodiplodia associated with mango in Brazil显示文摘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 Lasiodiplodia were used and identifications were made using a combination of morphology and phylogenetic analysis based on partial translation elongation factor 1-αsequence(EF1-α)and internal transcribed spacers(ITS).The following species were identified:Lasiodiplodia crassispora,L.egyptiacae,L.hormozganensis,L.iraniensis,L.pseudotheobromae,L.theobromae and Lasiodiplodia sp..Lasiodiplodia theobromae was the most frequently isolated species,which represented 41%of all the isolates.Only this species had been previously reported on mango in Brazil,while the other species represent the first report associated with mango tree diseases in this country.Lasiodiplodia crassispora is reported for the first time associated with mango diseases worldwide.There were significant differences in mycelial growth rates among the Lasiodiplodia species and also in the optimum temperature for growth.All species of Lasiodiplodia were pathogenic on mango fruit.There were significant differences in virulence among the species,wherein L.hormozganensis and Lasiodiplodia sp.were the most virulent,while the least virulent were L.iraniensis,L.pseudotheobromae,L.crassispora and L.egyptiacae. | Marília W.Marques Nelson B.Lima Marcos Antônio de Morais Jr Maria Angélica G.Barbosa Breno O.Souza Sami J.Michereff Alan J.L.Phillips Marcos P.S.Câmara | 2013 | Fungal Diversity2013，，4： | 2 |
| 3 | Botryosphaeria, Neofusicoccum, Neoscytalidium and Pseudofusicoccum species associated with mango in Brazil显示文摘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 relation to mycelial growth,pathogenicity and virulence.A total of 115 isolates were sampled and based on morphology and DNA sequence data(ITS and EF1-α)seven taxa were identified,namely,Botryosphaeria dothidea,B.mamane,Fusicoccum fabicercianum,Neofusicoccum parvum,N.brasiliense sp.nov,Neoscytalidium dimidiatum and Pseudofusicoccum stromaticum.B.dothidea and P.stromaticum were the most commonly isolated species,which represented 37%and 33%of all isolates respectively.B.mamane is reported for the first time in association with mango diseases worldwide.There were significant differences among the species obtained in this study in relation to optimum temperature for mycelial growth and mycelial growth rates.All species were pathogenic on mango fruit.There were significant differences in virulence among the species,with Ne.dimidiatum and N.parvum being the most virulent species,while P.stromaticum was the least virulent. | Marília W.Marques Nelson B.Lima Marcos A.de Morais Jr Sami J.Michereff Alan J.L.Phillips Marcos P.S.Câmara | 2013 | Fungal Diversity2013，，4： | 1 |
