“…In the current investigation, these two species could not be distinguished using ITS, TEF1α , and TUB2 sequence data alone or in combination. Neofusicoccum cryptoaustrale was originally isolated from Eucalyptus leaves ( Crous et al 2013 ) and shown to be pathogenic to this host by Pavlic-Zupanc et al (2017) . Neofusicoccum stellenboschiana was described by Yang et al (2017) using a strain originally isolated from, and shown to be pathogenic to grapevines in South Africa by Van Niekerk et al (2004) .…”

Trunk disease fungal pathogens reduce olive production globally by causing cankers, dieback, and other decline-related symptoms on olive trees. Very few fungi have been reported in association with olive dieback and decline in South Africa. Many of the fungal species reported from symptomatic olive trees in other countries have broad host ranges and are known to occur on other woody host plants in the Western Cape province, the main olive production region of South Africa. This survey investigated the diversity of fungi and symptoms associated with olive dieback and decline in South Africa. Isolations were made from internal wood symptoms of 145 European and 42 wild olive trees sampled in 10 and 9 districts, respectively. A total of 99 taxa were identified among 440 fungal isolates using combinations of morphological and molecular techniques. A new species of Pseudophaeomoniella, P. globosa, had the highest incidence, being recovered from 42.8 % of European and 54.8 % of wild olive samples. This species was recovered from 9 of the 10 districts where European olive trees were sampled and from all districts where wild olive trees were sampled. Members of the Phaeomoniellales (mainly P. globosa) were the most prevalent fungi in five of the seven symptom types considered, the only exceptions being twig dieback, where members of the Botryosphaeriaceae were more common, and soft/white rot where only Basidiomycota were recovered. Several of the species identified are known as pathogens of olives or other woody crops either in South Africa or elsewhere in the world, including species of Neofusicoccum, Phaeoacremonium, and Pleurostoma richardsiae. However, 81 of the 99 taxa identified have not previously been recorded on olive trees and have unknown interactions with this host. These taxa include one new genus and several putative new species, of which four are formally described as Celerioriella umnquma sp. nov., Pseudophaeomoniella globosa sp. nov., Vredendaliella oleae gen. & sp. nov., and Xenocylindrosporium margaritarum sp. nov.

“…This species causes severe lesions on the stem, branches and shoots, often resulting in the death of the host (Ismail et al, 2013;Guarnaccia et al, 2016). This fungus has been considered the main disease-causing pathogen in orchards of Vitis vinifera (Baskarathevan et al, 2012), Mangifera indica (Ismail et al, 2013), Persea americana (Guarnaccia et al, 2016) and Malus domestica (Rusin et al, 2019) and Eucalyptus plantations (Pavlic-Zupanc et al, 2017).…”

Filtrates from cultures of endophytic fungi isolated from leaves of Copaifera oblongifolia (Fabaceae) affect germination and seedling development differently

et al. 2023

Interactions between endophytic fungi (EFs) and their host plants range from positive to neutral to negative. The results of such interactions can vary depending on the organ of the infected host plant. EFs isolated from the leaves of some species of plants have potential for use as agents to inhibit seed germination and control invasive plants. The objectives of this study were to identify EFs present in the leaves of Copaifera oblongifolia and to evaluate the role of these fungi in seed germination and seedling development. A total of 11 species of EFs were isolated, which were identified using the internal transcribed spacers (ITS) sequence of the nuclear ribosomal DNA. The isolated species of EFs are generalists and probably are transmitted horizontally. Laboratory tests revealed that filtrates of these fungal isolates differently affect seed germination and seedling development of C. oblongifolia. The species Curvularia intermedia, Neofusicoccum parvum, Pseudofusicoccum stromaticum and Phomopsis sp. negatively affected seed germination, with N. parvum standing out for its negative effects, inhibiting seedling germination and survival in 89 and 222%, respectively. In addition, Cochliobolus intermedius negatively affected seedling development. Thus, the combined use of N. parvum and C. intermedius, or products from the metabolism of these microorganisms, in the control of invasive plants deserves attention from future studies.

The article considers the species composition of the Dothideomycetes and its structural characteristics in conditions of anthropogenically transformed ecosystems of the steppe zone of Ukraine. The materials of the work were the original mycological collection carried out as part of the mycological survey of this territory during 2008–2016, as well as the materials of the herbarium of the Institute of Botany named after M. Kholodny of the National Academy of Sciences of Ukraine. Herbarium collection and identification of the samples were performed in accordance with the generally accepted methods of cameral processing of xylotrophic, herbotrophic and coprothrophic micromycetes. To establish the taxonomic affiliation of species, the method of light microscopy was applied. As a result of our research, the species diversity of ascolocular fungi (Dothideomycetes) has been established in the anthropogenically transformed ecosystems of the steppe zone of Ukraine, which includes 156 species from 43 genera 19 families 5 orders and groups of taxa of Incertae sedis of the subclasses Dothideomycetidae and Pleosporomycetidae. The characteristic features of the taxonomic structure of the investigated mycobiota are the predominance of representatives of the order of Pleosporales, the families Cucurbitariaceae and Mycosphaerellaceae, the genera Cucurbitaria and Mycosphaerella. In the ecological structure of mycobiota in anthropogenically transformed ecosystems saprotrophic and xylotrophic species dominated. The ascolocular fungi species are form consortium connections with 178 species of vascular plants from 112 genera of 51 families, with the largest number of micromycetes (65 species) noted on plants of the Rosaceae. An analysis of the abundance of species in anthropogenically transformed ecosystems of the investigated area showed that 47% of the species are randomly distributed. Widespread species are Dothidea sorbi (Wahlenb.) Sacc., Cucurbitaria caraganae P. Karst., C. amorphae (Wallr.) Fuckel, Botryosphaeria dothidea (Moug.) Ces. & De Not., Otthia spiraeae (Fuckel) Fuckel. In the anthropogenically transformed ecosystems of the steppe zone of Ukraine, in comparison with natural ecosystems, the proportion of species from the genera Cucurbitaria and Mycosphaerella increases quantitatively, and the proportion of Leptosphaeria and Pleospora species decreases. An increase in the proportion of hemibiotrophic species in the ecological structure can be considered a characteristic feature of anthropogenic influence on mycobiota . Comparative analysis of quantitative and qualitative indicators of the mycobiota structure combined with spatial and temporal changes of these indicators can serve as an instrument for indicating its anthropogenic transformation. It would be promising to conduct further research on changes in the species structure of micromycetes exposed to various types of anthropogenic impact in terrestrial ecosystems of the steppe zone of Ukraine.
