Aim. The aim of the study was to establish genetic differences between V. album growing in different parts of Ukraine. Methods. White mistletoe samples collected in different regions of Ukraine were used in the study. The method of estimating the intron length polymorphism of β-tubulin genes was used. Amplified DNA fragments were fractionated by non-denaturing polyacrylamide gel electrophoresis and visualized by silver nitrate staining. Results. The genotypes of 91 white mistletoe plants were analyzed. DNA profiles of white mistletoe with a specific amplicons of β-tubulin gene introns were obtained, which allowed to differentiate the samples from each other. Fingerprinting data were used for cluster analysis and dendrogram construction. Conclusions. It was found that the analyzed mistletoe samples did not differ by geographical factor and were characterized by a low level of genetic diversity in the studied samples.

Aim. The aim of the work was to evaluate the possibilities of using the β-tubulin intron length (TBP, Tubulin Based Polymorphism) for genetic differentiation of ancient flax varieties (landraces), plants that was historically formed in Belarus. Methods. The β-tubulin first intron length polymorphism evaluating method (TBP) was used. Amplified fragments (β-tubulin introns) were fractionated by electrophoresis in non-denaturing polyacrylamide gel. DNA bands were detected using silver nitrate staining. Results. The size of the amplified fragments varied from 400 bp to 1900 bp. It was found that 25 of 30 studied varieties (landraces) were genetically heterogeneous. The total number of allele phenotypes was 7, and the value of PIC (Polymorphism Information Content) varied from 0.0 to 0.72. Conclusions. The data obtained make it possible to recommend landraces as a source of genes for increasing the genetic diversity of the existing flax gene pool, and the TBP method can be applied both in molecular-phylogenetic analysis and in molecular selection of flax.

Aim. The effectiveness of using the method of intron length polymorphism of β-tubulin genes is analyzed to evaluate the genetic diversity and polymorphism of tree plants by approbating it for a broad sample of tree plants of different taxonomic positions. Method. The method of estimation intron length polymorphism of β- tubulin (tubulin base polymorphism — TBP-method) has been tested. Results. The molecular genetic profiles and the unique patterns for the Quercus robur L., Populus tremula L., Fagus sylvatica L., Fagus sylvatica f. salicifolia, Robinia pseudoacacia L., Morus alba L., Ulmus glabra Huds., Betula pendula Roth., Acer platanoides L., Acer negundo L., Acer saccharinum Marshall, Catalpa bignonioides Walter, Tilia cordata Mill., Tilia platyphyllos Scop., Aesculus hippocastanum L., Populus nigra L., Juglans regia L., Fraxinus excelsior L., Alnus glutinosa (L.) Gaertn., Ginkgo biloba L. have been created. Some common fragments inherent in individual genera within the family have been found. Conclusions. TBP-method is rather convenient and reliable. It can be used both for molecular genetic marking and for the study of intra- and interspecific polymorphism of economically valuable, horticultural and forest trees.Keywords: TBP-method, β-tubulin introns, tree plants, genetic diversity.

Aim. Main aim of this research was identification of genetic distances between different genotypes of napa cabbage (B. rapa ssp. pekinensis) and diversity identification in var. glabra and var. laxa forms. Methods. Molecular genetic analysis of napa cabbage genotypes was conducted out using method of β-tubulin intron length polymorphism (TBP). Results. Molecular profiles of different napa cabbage (B. rapa ssp. pekinensis) genotypes were identified. Number of amplified β-tubulin intron fragments was significantly varying – from 12 to 24 for each genotype. Basing on obtained results a dendrogram was built, which shows genetic distances among studied accessions. Conclusions. In present study 7 genotypes of B. rapa ssp. pekinensis were analyzed, received from IPK (Gatersleben) and Crop Research Institute (Prague) gene banks. Basing on obtained results it was established that systematic diversification of two forms var. glabra and var. laxa is not being confirmed by molecular genetic methods, such as TBP, and in this case, genetic difference between populations and cultivars was more significant.
