Multi-gene analysis and morphology reveal novel Ilyonectria species associated with black foot disease of grapevines

Grapevine Trunk Diseases in British Columbia: Incidence and Characterization of the Fungal Pathogens Associated with Black Foot Disease of Grapevine

“…Both micro-and macroconidia were produced by all isolates on PDA, and measurements from each type of conidium from each species including the ex-type specimens are given in Table 4. Colony and conidia morphology allowed us to separate all isolates in five different morphological groups by comparison to reference isolates from CBS and previously published data (10,23,32).…”

“…This is not surprising because botb species are known to be tbe main fungi associated witb black foot disease of grapevines elsewhere, and tbe abundance of eitber or botb species bas been similarly found in vineyards in Australia (49), California (32,34), Cbile (6), Iran (28). New Zealand (22), Portugal (8,10), eastern Canada (31), Spain (5), South Africa (22,23), and Uruguay (1). Tbis study describes for tbe first time tbe occurrence in North America of C. pauciseptatum, a recently described Cylindrocarpon species tbat to date has been reported to occur in New Zealand (39), Slovenia (39), Soutb Africa (44).…”

Characterization of Cylindrodendrum, Dactylonectria and Ilyonectria isolates associated with loquat decline in Spain, with description of Cylindrodendrum alicantinum sp. nov.

“…It is well known that these are soil-borne fungi, which are generally regarded as pathogens and/or saprobes of various hosts and substrates, associated with a variety of disease symptoms that include rot of roots, stems and cuttings of agricultural, forestry and horticultural crops (Halleen et al 2006;Schroers et al 2008;Chaverri et al 2011;Cabral et al 2012b;Agustí-Brisach and Armengol 2013;Lombard et al 2014). Recently, species belonging to this group of fungi have been isolated from fruit trees showing root rot symptoms, such as avocado (Persea americana) (Vitale et al 2012), kiwifruit (Actinidia chinensis) (Erper et al 2013) and Arecaceae palms (Aiello et al 2014).…”

Studies on the epidemiology of black-foot disease of grapevine in Spain

“…Thus, in order to clarify this hypothesis, Cabral et al (2012c) . Isolates belonging to Neonectria mammoidea group have also been associated with this disease in Canada .…”

“…Moreover, Cabral et al (2012c), have just demonstrated the existence of polymorphism into I. macrodidyma-complex. This hypothesis is in agreement with the results obtained by Alaniz et al (2009), who already detected relevant genetic diversity in "C." macrodidymum by using inter-simple sequence repeat (ISSR) technique.…”
