Botryosphaeriaceae species affecting table grape vineyards in Chile and cultivar susceptibility Ciencia e Investigación Agraria
Morales,Andrea; Latorre,Bernardo A; Piontelli,Eduardo; Besoain,Ximena.
Several Botryosphaeriaceae species have been identified as the causes of cankers and dieback of Vitis vinifera in several grape-growing regions around the world. This research was conducted to further study the species of Botryosphaeriaceae associated with table grapes in Chile, to estimate the prevalence and severity of the disease as a function of vineyard age, to study the susceptibility of table grape cultivars to infection by Botryosphaeriaceae species, and to evaluate the effect of tissue age on the infection caused by Botryosphaeriaceae species. Symptoms were characterized by the presence of the partial or total death of the grapevine cordons and distorted leaves. Brown V-shaped or U-shaped cankers and black spots were observed in cross-sections,...

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...

Organismos asociados a la pudrición del cogollo de la palma aceitera (Elaeis guineensis Jacq) en San Lorenzo, Ecuador Rev. Protección Veg.
Rivas Figueroa,Fernando; Herrera Isla,Lidcay.
El presente trabajo se realizó con el objetivo de aislar los microorganismos asociados a la enfermedad Pudrición del Cogollo de la palma aceitera. Para ello, se seleccionaron plantas con manifestaciones de los síntomas característicos de la enfermedad y se tomaron fragmentos de los tejidos afectados. Las muestras se lavaron en agua corriente durante 15 minutos, luego se desinfectaron con hipoclorito de sodio al 2% (v/v) por 5 minutos y, finalmente, se lavaron con agua destilada estéril. Las secciones de tejidos se secaron en papel filtro estéril en cámara de flujo laminar y se colocaron en medio Agar Agua estéril al 2% y se incubaron a 25ºC± 1. Las estructuras observadas se sembraron en medios estériles PDA 3,8% y Agar Nutriente 2,8% para aislar los hongos...

Resolving the Diplodia complex on apple and other Rosaceae hosts Naturalis
Phillips, A.J.L.; Lopes, J.; Abdollahzadeh, J.; Bobev, S.; Alves, A..
Diplodia species are known as pathogens on many woody hosts, including fruit trees, worldwide. In this study a collection of Diplodia isolates obtained mostly from apple and other Rosaceae hosts were identified based on morphological characters and DNA sequence data from ITS and EF1-α loci. The results show that the diversity of species associated with twig and branch cankers and fruit rot of apples is larger than previously recognised. Four species were identified, namely D. seriata and D. malorum (which is here reinstated for isolates with D. mutila-like conidia). Diplodia intermedia sp. nov. is closely related to D. seriata, and D. bulgarica sp. nov. is morphologically and phylogenetically distinct from all Diplodia species reported from apples.

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...
