“…Meanwhile, fungal evenness was rather low, due to the high presence of a few taxa (dominance) previously commented. Interestingly, this finding accords with studies of fungal endophytes in pine twigs [54]. Moreover, lower values of fungal diversity were reported for ophiostomatoid fungi associated with T. piniperda, as described by Romón et al [55,56] in Spain.…”

“…Nevertheless, regarding previously discussed ecological indicators, it is possible to conclude that mycobiota were sufficiently characterised. Results from evaluating fungal community composition by their taxonomical placement agreed with other studies where Dothideomycetes and Sordariomycetes were the main taxonomic groups of fungal communities inhabiting pine species [52,54].…”

“…are frequent in the tissues of pines such as sapwood, needles and twigs [73,74] and are also carried by bark beetles [53,70,75]. Sanz-Ros et al [54] found high rates of appearance of Phoma herbarum Westend in P. sylvestris supporting the endophytic role of this fungus.…”

Bark beetles (Coleoptera, Scolytinae) carry a diverse filamentous fungal community sometimes acting as vectors or carriers of phytopathogens. In this study, mycobiota carried by two Tomicus species (Tomicus piniperda and Tomicus destruens) were investigated through (i) morphological and molecular identification of taxa; (ii) taxonomic richness, diversity, evenness, dominance and phoresy indices; (iii) ecological network analysis and (iv) statistical co-occurrence analysis. The studied mycobiota were formed by eleven taxa and showed a moderate fungal diversity with low evenness. The fungus Sydowia polyspora was significantly abundant and dominated the community. All the fungal taxa were randomly associated. Both insect species (T. piniperda and T. destruens) were collected from plantations of Pinus radiata infected by Fusarium circinatum. The ecological factors that could drive community ecology and phoretic links between fungi and bark beetles are discussed.

Ophiostomatales associated with wounds on hardwood trees in Poland

et al. 2019

Wounds on trees provide entrance for many members of the Ophiostomatales (Ascomycota), including economically damaging tree pathogens. Because very little is known regarding wound‐associated fungi on hardwoods in Europe or their potential nitidulid beetle vectors (Coleoptera), the aim of this survey was to explore the diversity of these fungi in Poland. Wound samples associated with 26 tree species were collected from 18 stands in Poland. Fungi belonging to the Ophiostomatales were isolated and identified based on morphology and DNA sequence comparisons of five gene regions, combined with phylogenetic analyses. In total, 32 taxa were identified, including 20 known and 12 currently undescribed species. In addition, Grosmannia cainii, Ophiostoma cf. ponderosae, O. sparsiannulatum and Sporothrix aurorae were reported for the first time outside of the USA. The wound‐associated members of the Ophiostomatales recovered from hardwoods showed high diversity and specificity. Among the species recovered, 16 belonged to Sporothrix, 11 represented Ophiostoma s. l., five could be assigned to Leptographium s. l., and one Graphilbum species was detected. Among the studied tree species, wounds on Quercus robur appeared to be the most vulnerable to infection by members of the Ophiostomatales. All the nitidulid beetle species were found in association with species assignable to Ophiostoma and Sporothrix. This study detected a significant association between the occurrence of species belonging to the Ophiostomatales and the health status of the wounded trees. Some of the isolated species were host specific although Ophiostoma quercus, the most frequently encountered species, had a broad host range.

“…Endophytic fungi are able to spend the entire or part of their life cycle within plant tissues, in either the apoplast or symplast, without causing visible symptoms to the host plants (Saikkonen et al, 1998). Many endophytic fungi promote host growth and provide increased tolerance towards biotic and abiotic stresses (Pirttil€ a & Frank, 2011;Sanz-Ros et al, 2015). There is increasing evidence that the way by which endophytes confer higher tolerance to pathogens is linked to interactions between beneficial microorganisms and plants, which in turn trigger an immune defensive response reaction against pathogens (Zamioudis & Pieterse, 2012).…”

Environmentally friendly methods for controlling pine pitch canker

et al. 2019

View full text Add to dashboard Cite

Fusarium circinatum is a highly virulent invasive pathogen that causes the disease commonly known as pine pitch canker (PPC). On mature trees, the most common symptoms of PPC include resin bleeding, resinous cankers, wilting of needles and dieback. In nurseries the main symptoms are yellowish needles, and wilting of foliage and shoots. PPC is considered one of the most important diseases of conifers globally and at least 60 species of Pinus along with Pseudotsuga menziesii are known to be susceptible. Quarantine regulations are crucial to minimize the risk of new introductions into disease‐free countries. However, if these measures fail, implementation of environmentally friendly control methods is currently encouraged in an integrated management approach that minimizes the use of chemicals in forests. This review therefore summarizes current knowledge of biological control using endophytic fungi, bacteria and viruses, and other environmentally friendly methods to control PPC, including thermotherapy, natural products with fungicidal effects, promoters of innate host resistance mechanisms and breeding for resistance. Key research gaps to be addressed for improvement of effective management of this disease are discussed.
