During surveys of Phytophthora diversity in natural and semi-natural Fagaceae forests Austria, Italy Portugal, four new cryptic species were isolated from rhizosphere soil samples. Multigene phylogeny based on nuclear ITS, ß-tubulin HSP90 mitochondrial cox1 NADH1 gene sequences demonstrated that two species, P. tyrrhenica vulcanica spp. nov, belong to phylogenetic Clade 7a, while the other castanetorum tubulina clustered together with quercina forming a clade, named here as 12. All are...
The taxonomic status of Colletotrichum gloeosporioides sensu lato ( s.l .) associated with olive anthracnose is still undetermined and the pathogenic ability this species complex controversial. In present study, isolates obtained from provisionally identified as C. . on basis morphological cultural features were reclassified using ITS TUB2 DNA barcode markers referred to seven distinct species, recently separated within aenigma , stricto s.s .), kahawae queenslandicum siamense theobromicola...
The plant microbiome plays an important role in biology, ecology, and evolution. While recent technological developments enabled the characterization of plant-associated microbiota, we still know little about impact different biotic abiotic factors on diversity structures these microbial communities. Here, characterized structure bacterial microbiomes fruits, leaves, soil collected from two olive genotypes (Sinopolese Ottobratica), testing hypothesis that genotype would each compartment with...
The genetic diversity of Phytophthora spp. was investigated in potted ornamental and fruit tree species. A metabarcoding approach used, based on a semi‐nested PCR with genus‐specific primers targeting the ITS 1 region rDNA . More than 50 sequence types representing at least 15 distinct taxa were detected. Nine had sequences that grouped them defined taxonomic groups ( P. nicotianae , citrophthora meadii P taxon Pgchlamydo cinnamomi parvispora cambivora niederhauserii lateralis ) whereas...
A metagenomic approach based on the use of genus specific primers was developed and utilized to characterize Colletotrichum species associated with olive phyllosphere carposphere. Selected markers enabled amplification almost entire ITS1-5.8S-ITS2 region rDNA its as barcode gene. The analysis different samples (green senescent leaves, floral residues, symptomatic asymptomatic fruits, litter leaves mummies) in three phenological phases (June, October December) detection 12 genotypes 4...
Abstract Between 2010 and 2015, an extensive survey of Phytophthora diversity was performed across Portugal. Baiting direct isolation tests obtained 48 taxa in 62 70 forest stands (89%) from 148 302 rhizosphere soil samples (49%) 25 29 tree species (86%), bark cankers Alnus lusitanica Fagus sylvatica ; 33 34 rivers streams (97%); 12 13 nurseries (92%) 54 87 root ball (61%) 16 21 (76%). The 799 isolates belonged to 28 known three recently described species; one designated two new non‐hybrid...

Despite the critical role of soil microbiomes in ecosystem stability, how disturbance impacts these communities and their interactions with plants remains poorly understood. In this study, we investigate different levels influence assembly robustness root fungal microbiome. Using a microcosm experiment, inoculated from environments decreasing - agricultural field, field margin, uncultivated tested variation composition, process, network stability Our results reveal that more disturbed...
Four different fungi (Trichoderma viride, T. harzianum, Phomopsis sp., and Mortierella sp.) were isolated from 6-year-old Pinus nigra plants showing stunting high incidence of mortality in a reforestation area the National Park Abruzzo, Lazio, Molise (central Italy). Tests conducted on P. revealed pathogenic behavior viride isolates with 30 to 80% artificially inoculated 2-year-old seedlings. The pathogenicity these was also observed 10-year-old trees lemon fruit. This result, agreement...
Abstract The Valdivian rainforest, one of the global hotspots biodiversity, is a temperate rainforest originating as Tertiary relic from supercontinent Gondwana. In November 2014, survey Phytophthora diversity was performed in 13 natural forest stands and 20 streams rivers two protected areas near Valdivia montane Concepción area. One planted stand each introduced tree species Castanea sativa Fagus sylvatica were also included. Using baiting assays, eight described four previously unknown...
Postharvest biocontrol agents are considered a viable alternative to the use of synthetic chemicals as demonstrated by extensive research conducted scientists and companies worldwide. In present investigation, potential carotenoid-producing basidiomycetous yeast isolated from table grape flowers was analyzed. The strain RY1 proved be Sporobolomyces roseus. vitro in vivo tests were assess its efficacy against Penicillium expansum, one most important postharvest pathogens producer mycotoxin...
Molecular analyses of a large population isolates, previously identified as group B or genetic A4 the Colletotrichum acutatum species complex, mainly Italian origin from olive, but also other hosts collected since 1992, confirmed well-resolved phylogenetic lineage with distinctive phenotypic characters which can be recognized separate species. Based on RAPD genomic fingerprinting, ITS and β-tubulin DNA sequences, this was clearly distinct C. sensu stricto , fioriniae simmondsii well groups...
During an oomycete survey in December 2015, 10 previously unknown Halophytophthora taxa were isolated from marine and brackish water of tidal ponds channels saltmarshes, lagoon ecosystems river estuaries at seven sites along the Algarve coast South Portugal. Phylogenetic analyses LSU ITS datasets, comprising all described species, new relevant distinctive sequences available GenBank, provided updated phylogeny genus s. str. showing for first time a structure clades designated as Clades 1–10....
The characterization of Basidiomycetes associated with wood rots in commercial citrus orchards southern Italy revealed that both white and brown rot fungi are implicated this disease. Fomitiporia mediterranea was the most prevalent species causing a rot, followed by Fomitopsis sp. which, contrast, decay. Furthermore, Phellinus spp. other nonidentified basidiomycetous showing genetic affinity genera Coniophora were occasionally isolated. Artificial inoculations on lemon (Citrus limon)...
Abstract Background and aims The Kiwifruit Vine Decline Syndrome (KVDS) is a disease that currently challenge for kiwifruit production in Italy, it spreading new areas. However, the causal agent of this syndrome has not been clearly identified, we still know little about overall effects KVDS on interactions between host plant its microbiome. Methods In study, combined metabarcoding targeted isolation (leaf baiting) to characterize changes rhizosphere root microbiomes associated with symptoms...

The cultivation of yellow- and red-fleshed kiwifruit (Actinidia chinensis) is rapidly spreading. In May 2023, canker lesions on shoots were observed approximately 20% the in an orchard A. chinensis cv. Jintao southern Italy (38°21'44.69"N, 15°55'23.92"E). Symptoms consisted dark brown lesions, rots bark internal tissues, abundant production a white mycelium (Figure 1). Infected died within few days after onset symptoms. Following incubation moist chamber, several round or oval black...
This paper is the first report of symptoms caused by Alternaria alternata on aboveground organs olive plants in Italy. On leaves, included spots and necroses frequently associated with damage thrips (Liothrips oleae). fruits, browning pedicels, fruitlets soon after fruit set, rot mummification mature fruit. Several isolates A. identical morphological features DNA sequences were all different symptoms. The impacts production can be severe, infections to pedicels are particularly relevant as...
