“…isolates found in this investigation belong to group AG-F, which coincides with earlier works on root rot in watermelon carried out in Arizona, U.S.A (Nischwitz et al, 2013) and Italy (Aiello et al, 2012). Ceratobasidium AG-F is also the causal agent of root rot in strawberry (Sharon et al, 2007), Tagetes erecta (Saroj et al, Revista Mexicana de FITOPATOLOGÍA Mexican Journal of Phytopathology Publicación en línea, mayo 2018…”

Resumen. El estado de Sonora es uno de los principales productores de sandía en México. Cada año, los productores locales enfrentan problemas fitosanitarios, provocados principalmente por hongos del suelo. En el presente estudio se analizó la presencia de hongos patógenos asociados con pudrición de raíz en plantas de sandía en las dos zonas de mayor producción en Sonora. Abstract. The state of Sonora is one of the main producers of watermelons in Mexico. Each year, agricultural producers deal with phytosanitary issues like soilborne pathogens. In this study the presence of phytopathogenic fungi associated to watermelon root rot was analyzed in the main production regions of Sonora. Morphological analysis revealed three genera: Fusarium (73%), Ceratobasidium (20%) and Rhizoctonia (6%). Through a multilocus phylogenetic analysis (ITS1, TEF and RPB2 for Fusarium; ITS1 and RPB2 for Rhizoctonia and Ceratobasidium), the following species were identified: Fusarium falciforme, F. brachygibbosum and F. oxysporum. In addition to this, two anastomosic groups for Ceratobasidium sp. (AG-F y AG-A) and two for Rhizoctonia spp.(AG-4 y AG-6) were identified. Pathogenicity assays showed that the representative isolates from these five different species caused root rot wounds and wilting in watermelon plantlets 21 234Fully Bilingual

“…A large number of Ceratobasidiaceae were found after cloning of the PCR amplification products, while in vitro isolation failed to reveal the presence of these fungi in the majority of samples. Sequences from samples MR1, MR2 and MR3 shared similarity with Ceratobasidium sequences from Fragaria ananassa plants collected in Israel [37]. The closest match for the sequences amplified from sample MR5 was with Ceratobasidiaceae found in roots of Epipactis gigantea collected in California and Oregon [38].…”

Analysis of fungal diversity in Orchis tridentata Scopoli

et al. 2012

We have assessed the identities of fungi associated with Orchis tridentata, an endangered orchid species growing in open woodland and poor grassland of Central and Southern Europe. Fungal diversity in ten O. tridentata adult individuals collected in two protected areas of Central Italy was analysed by means of morphological and molecular methods. Sequencing of the cloned ITS fungal inserts corresponding to the dominant PCR products obtained from amplification of total root DNA with ITS1F and ITS4 primers revealed a variety of fungal species occurring in O. tridentata roots. Among them, members of the basidiomycete families Ceratobasidiaceae, Tulasnellaceae and Hymenogastraceae were recovered, together with ascomycetes belonging to Leptodontidium and Terfezia. The implications of these results in the understanding of O. tridentata biology and for the conservation of this threatened orchid species are discussed.

Samples of strawberry transplants were randomly collected from 47 growers in Aydın province of Turkey. A total of 10 Rhizoctonia isolates were identified by morphological characterization, analysis of rDNA-ITS sequences. Pathogenicity tests were carried on strawberry seedlings and detached stolon. Ten pathogenic binucleate Rhizoctonia isolates were defined as AG-A, AG-G and AG-K on the basis of ITS region sequence analysis. To our knowledge, this is the first report of the presence of Rhizoctonia fragariae in strawberry transplants in Turkey.
