Botryosphaeriaceae from Eucalyptus plantations and adjacent plants in China Naturalis
Li, G.Q.; Liu, F.F.; Li, J.Q.; Liu, Q.L.; Chen, S.F..
The Botryosphaeriaceae is a species-rich family that includes pathogens of a wide variety of plants, including species of Eucalyptus. Recently, during disease surveys in China, diseased samples associated with species of Botryosphaeriaceae were collected from plantation Eucalyptus and other plants, including Cunninghamina lanceolata, Dimocarpus longan, Melastoma sanguineum and Phoenix hanceana, which were growing adjacent to Eucalyptus. In addition, few samples from Araucaria cunninghamii and Cedrus deodara in two gardens were also included in this study. Disease symptoms observed mainly included stem canker, shoot and twig blight. In this study, 105 isolates of Botryosphaeriaceae were collected from six provinces, of which 81 isolates were from Eucalyptus...

Caulicolous Botryosphaeriales from Thailand Naturalis
Trakunyingcharoen, T.; Lombard, L.; Groenewald, J.Z.; Cheewangkoon, R.; To-anun, C.; Crous, P.W..
Members of Botryosphaeriales are commonly encountered as endophytes or pathogens of various plant hosts. The Botryosphaeriaceae represents the predominant family within this order, containing numerous species associated with canker and dieback disease on a wide range of woody hosts. During the course of routine surveys from various plant hosts in Thailand, numerous isolates of Botryosphaeriaceae, including Aplosporellaceae were collected. Isolates were subsequently identified based on a combination of morphological characteristics and phylogenetic analysis of a combined dataset of the ITS and EF1-α gene regions. The resulting phylogenetic tree revealed 11 well-supported clades, correlating with different members of Botryosphaeriales. Other than confirming...

Incidencia de enfermedades fúngicas en plantaciones de cacao de las provincias orientales de Cuba Rev. Protección Veg.
Martínez de la Parte,Einar; Pérez Vicente,Luis.
Durante una encuesta fitopatológica, se visitaron 20 fincas cacaoteras en la región oriental de Cuba, cuatro en la provincia Granma y 16 en Baracoa, donde se muestrearon mazorcas y hojas enfermas, chancros del tronco, agallas y otras manifestaciones de enfermedad. Las muestras se desinfectaron (NaOCl, 3%), se lavaron con agua destilada estéril, montadas en cámaras húmedas y/o sembradas en agar agua + vancomicina (200 ug/ml) o medio selectivo para Phytophthora spp. Los hongos que con mayor frecuencia se encontraron fueron Lasiodiplodia theobromae Griffiths & Maubl. (90%), Phytophthora palmivora (E.J. Butler) (85%) y Colletotrichum gloeosporioides (Penz.) Sacc. (70%). No se hallaron aislamientos típicos de P. tropicalis. Las enfermedades de mayor...

Phylogeny and morphology of four new species of Lasiodiplodia from Iran Naturalis
Abdollahzadeh, J.; Javadi, A.; Mohammadi Goltapeh, E.; Zare, R.; Phillips, A.J.L..
Four new species of Lasiodiplodia; L. citricola, L. gilanensis, L. hormozganensis and L. iraniensis from various tree species in Iran are described and illustrated. The ITS and partial translation elongation factor-1α sequence data were analysed to investigate their phylogenetic relationships with other closely related species and genera. The four new species formed well-supported clades within Lasiodiplodia and were morphologically distinct from all other known species.

Phytochemical and antifungal activity of anthraquinones and root and leaf extracts of Coccoloba mollis on phytopathogens BABT
Barros,Iuri Bezerra de; Daniel,Juliana Feijó de Souza; Pinto,Jurandir Pereira; Rezende,Maria Inês; Braz Filho,Raimundo; Ferreira,Dalva Trevisan.
The aim of this work was to study the phytochemical and antifungal activity of anthraquinones and root and leaf extracts of Coccoloba mollis on phytopathogens. The chemical analysis of ethanolic extracts showed a mixture of long-chain hydrocarbons, carboxyl esters and 3-taraxerone in the leaf extract. Two anthraquinones (emodin and physcion) were isolated and identified from the root extract. Phytochemical screening using the pharmacognostic methods revealed the presence of flavonoids and tannins in the leaves and roots. Anthraquinones were only found in the root extract, no alkaloids, coumarins, saponins and simple phenolics were present. The antifungal activity of C. mollis extracts and anthraquinones isolated from the root of this plant against...

Resolving the phylogenetic and taxonomic status of dark-spored teleomorph genera in the Botryosphaeriaceae Naturalis
Phillips, A.J.L.; Alves, A.; Pennycook, S.R.; Johnston, P.R.; Ramaley, A.; Akulov, A.; Crous:, P.W..
Species in the Botryosphaeriaceae are common plant pathogens and saprobes found on a variety of mainly woody hosts. Teleomorphs typically have hyaline, aseptate ascospores. However, some have been reported with brown ascospores and their taxonomic status is uncertain. A multi-gene approach (SSU, ITS, LSU, EF1-α and β-tubulin) was used to resolve the correct phylogenetic position of the dark-spored ‘Botryosphaeria’ teleomorphs and related asexual species. Neodeightonia and Phaeobotryon are reinstated for species with brown ascospores that are either 1-septate (Neodeightonia) or 2-septate (Phaeobotryon). Phaeobotryosphaeria is reinstated for species with brown, aseptate ascospores that bear an apiculus at either end. The status of Sphaeropsis is clarified...
