Based on these characteristics, natural melanin holds significant potential for applications in the fields of biomedicine, nanotechnology and materials science. Along with that, the exploration of organisms producing natural melanin remains relevant and filamentous fungi with their exceptional metabolic versatility are promising sources of these pigments. Wood-inhabiting fungi in particular are known to produce specific types of melanin as secondary metabolites. This study aimed to quantify and characterise melanin in the mycelium of various strains of Xylaria polymorpha, a common representative of wood-inhabiting fungi. As a result, among the ten studied strains of X. polymorpha, the highest melanin synthesis productivity was observed in the strain IBK 2737, reaching 180.32 ± 4.16 mg/l, while the lowest was recorded in the strain IBK 2723 at 5.17 ± 0.36 mg/l. This investigation highlights that X. polymorpha strains from the IBK Culture Collection show promise as a valuable source of natural melanin.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140431865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, C. microcarpa (as currently understood) is a genetically non-uniform and morphologically variable species that consists of several distinct ribotypes and cytotypes with varying ploidy levels. Little-pod false flax diversity remains understudied in Ukraine, despite the country is one of genetic diversity hotspots of this species. Therefore, in the present study we aimed to clarify the distribution patterns of C. microcarpa and its various infraspecific forms in Ukraine, based on the collections of the National Herbarium of Ukraine (KW). In particular, it has been demonstrated that C. microcarpa occurs at present over the almost whole territory of Ukraine and is represented by two distinct hexaploid cytotypes, as well as by two Western-type ribotypes (W1 and W2).The obtained results clarify the actual distribution range of C. microcarpa in Ukraine and for the first time allows to delineate its various forms there, which in the future can be used for further studies of the population structure of representatives of C. microcarpa in Ukraine.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140428556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The plant communities of artificial plantations dominated by northern red oak have such general features as poor species composition, with projective coverage values of other species not exceeding 5%, and a simplified vertical structure of the tree layers. In natural forest plant communities with the participation of Q. rubra, there are no rare and typical nemoral dominant species, which results in disruption of consortial relations in ecosystems. Such changes are due to the biological and ecological peculiarities of this species, in particular, its dense crown, abundant biomass of leaves, which reduces lighting, and allelopathic properties; all those factors affect the physical and chemical characteristics of biotopes. Quercus rubra artificial plantations are more adaptive to changes of natural conditions and are able to withstand harsher winters and lack of precipitation. The ecological amplitude of this species is wide, and even with an increase in the average annual temperature by 3 °C most of the ecological indicators do not go beyond the optimum zone of the species, except for the soil moisture and thermal regime. The amplitudes of main indicators of ecological factors of temperate forests and Q. rubra artificial plantations overlap. The dominance of Q. rubra reduces the quality of ecosystem services of native forests. The high competitive advantages of Q. rubra are the reason for the impossibility of natural restoration of the typical broad-leaved or coniferous forests on those land plots where they were replaced by artificial plantations of northern red oak or its tree layers were formed as the results of the spontaneous distribution of this species. In the successions, the communities with the participation of northern red oak are potentially able to replace the native forest phytocoenoses.","PeriodicalId":52835,"journal":{"name":"Ukrainian Botanical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138951986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besser (KW-BESS) at the National Herbarium of Ukraine (KW) contains at least 1186 herbarium sheets. The collection of specimens of Artemisia is stored in folders Nos. 234–249 of the Besser herbarium. Each folder contains individual paper folders (here termed taxon covers). In total, there are 217 individual taxon folders. Our analysis of protologues and herbarium labels demonstrated that the KW-BESS collection contains types and/or other original specimens in 118 taxon folders, but much more actual types of species-rank and infraspecific names. Additional analysis of their possible type status is needed for specimens in 28 taxon folders. The KW-BESS collection contains authentic and historical specimens of such famous researchers and collectors of the 19th century as A. Bunge, L.K.A. Chamisso, A.P. de Candolle, D. Douglas, J.F.G.
