“…Similarly, four previously described Ophiognomonia species known from Picea rubens (O. acadiensis) (detected at all sites other than the highly impacted site in our study), or from Betula and Alnus sp. (O. alni-viridis, O. intermedia) (located at three of our sites) and O. ischnostyla were reported by our study [27,[38][39][40]. Ophiognomonia species were also found during our study.…”

Eastern Mountain Avens (Geum peckii Pursh, Rosaceae) is a globally rare and endangered perennial plant found only at two coastal bogs within Digby County (Nova Scotia, Canada) and at several alpine sites in the White Mountains of New Hampshire (USA). In Canada, the G. peckii population has declined over the past forty years due in part to habitat degradation. We investigated the culturable foliar fungi present in G. peckii leaves at five locations with varying degrees of human impact within this plant species’ Canadian range. Fungal identifications were made using ITS rDNA barcoding of axenic fungal cultures isolated from leaf tissue. Differences in foliar fungal communities among sites were documented, with a predominance of Gnomoniaceae (Class: Sordariomycetes, Phylum: Ascomycota). Habitats with more human impact showed lower endophytic diversities (10–16 species) compared to the pristine habitat (27 species). Intriguingly, several fungi may represent previously unknown taxa. Our work represents a significant step towards understanding G. peckii’s mycobiome and provides relevant data to inform conservation of this rare and endangered plant.

“…Nowadays, special attention has been paid to studies of taxonomic groups of endophytes, potential ways of colonization of plant tissues and organs [ 12 , 13 ], physiological processes responsible for the formation of the acquired resistance of plants [ 14 , 15 , 16 ], and plant-microbial interactions and expression of related genes [ 17 , 18 , 19 , 20 ]. Some species of endophytic bacteria are capable of fixing atmospheric nitrogen [ 21 , 22 , 23 , 24 ].…”

Europe’s forests, particularly in Ukraine, are highly vulnerable to climate change. The maintenance and improvement of forest health are high-priority issues, and various stakeholders have shown an interest in understanding and utilizing ecological interactions between trees and their associated microorganisms. Endophyte microbes can influence the health of trees either by directly interacting with the damaging agents or modulating host responses to infection. In the framework of this work, ten morphotypes of endophytic bacteria from the tissues of unripe acorns of Quercus robur L. were isolated. Based on the results of the sequenced 16S rRNA genes, four species of endophytic bacteria were identified: Bacillus amyloliquefaciens, Bacillus subtilis, Delftia acidovorans, and Lelliottia amnigena. Determining the activity of pectolytic enzymes showed that the isolates B. subtilis and B. amyloliquefaciens could not cause maceration of plant tissues. Screening for these isolates revealed their fungistatic effect against phytopathogenic micromycetes, namely Fusarium tricinctum, Botrytis cinerea, and Sclerotinia sclerotiorum. Inoculation of B. subtilis, B. amyloliquefaciens, and their complex in oak leaves, in contrast to phytopathogenic bacteria, contributed to the complete restoration of the epidermis at the sites of damage. The phytopathogenic bacteria Pectobacterium and Pseudomonas caused a 2.0 and 2.2 times increase in polyphenol concentration in the plants, respectively, while the ratio of antioxidant activity to total phenolic content decreased. Inoculation of Bacillus amyloliquefaciens and Bacillus subtilis isolates into oak leaf tissue were accompanied by a decrease in the total pool of phenolic compounds. The ratio of antioxidant activity to total phenolic content increased. This indicates a qualitative improvement in the overall balance of the oak leaf antioxidant system induced by potential PGPB. Thus, endophytic bacteria of the genus Bacillus isolated from the internal tissues of unripe oak acorns have the ability of growth biocontrol and spread of phytopathogens, indicating their promise for use as biopesticides.

The saplings extractor is intended primarily for replanting all types of seedling forest trees included a bale of soil without disturbing the root system. Trees growing along roads or already grown to a certain extent trees in the landscape are often need to be transplanted due to landscaping or urban planning. These trees can be used, for example, in popular tourist localities, where they can speed up the regeneration of the landscape and make visitors' stay more pleasant. However, this activities shouldn't be provided only manually, but some advanced technologies have to be used. The goal of this paper is presenting a new technology for mechanized planting using the production potential of the seedling trees. The principle of the saplings extractor lies in excavating a pit at the site that will be the subject of tree replanting, and then transplanting the pre-lifted up seedling forest tree into the prepared excavated pit. The last phase is to backfill the pit all around with soil from the excavated pit after the sapling was picked up. This paper emphasise the economic advantages of new technology and provides the saplings planting solutions in the form of landscaping, road tree rows or ornamental trees in an urbanized environment.
