Kuzeneva (basionym B. sibakademica Baranov) and white-barked B. pubescens var. pubescens, and (2) dark-barked B. kotulae Zaverucha = B. pendula var. obscura (Kotula ex Fiek) Olšavská (basionym B. obscura Kotula ex Fiek, heterotypic synonym B. kotulae) and white-barked B. pendula, respectively. Using published data and sequences obtained in this study, it was found that, although these pairs can be distinguished not only by morphological characters but also by two diagnostic single nucleotide polymorphisms (SNPs) in the internal transcribed spacers ITS1 and ITS2, no sequence differences within each pair were detected. These results suggest that the colour of the bark cannot be used as a taxonomic trait at the species level, and the dark-barked birches within each pair should not be treated as separate species or varieties, but as forms, respectively. Therefore, we reassessed the taxonomic status of B. sibakademica and B. kotulae using morphological traits and molecular genetic markers and suggest that B. pubescens f. sibakademica (Baranov) Tarieiev comb. nov. and B. pendula f. obscura (Kotula ex Fiek) Tarieiev comb. nov. should be used for them, respectively. Betula pubescens f. sibakademica was described in Ukraine for the first time."],["dc.identifier.doi","10.1093/botlinnean/boz031"],["dc.identifier.scopus","2-s2.0-85073558911"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65313"],["dc.identifier.url","http://www.scopus.com/inward/record.url?eid=2-s2.0-85073558911&partnerID=MN8TOARS"],["dc.language.iso","en"],["dc.relation.eissn","1095-8339"],["dc.relation.issn","0024-4074"],["dc.subject.gro","bark colour"],["dc.subject.gro","ITS"],["dc.subject.gro","molecular markers"],["dc.subject.gro","morphology"],["dc.subject.gro","SNPs"],["dc.title","Taxonomy of dark-and white-barked birches related to Betula pendula and B. pubescens (Betulaceae) in Ukraine based on both morphological traits and DNA markers"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
