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. Keywords: Viscum album L., intron length polymorphism, β-tubulin, genetic variability, Ukraine.

Distribution Record

In Madagascan waters, both Tetraclita rufotincta Pilsbry 1916 and T. africana Ren 1989 have been reported. Tetraclita rufotincta is more widely distributed than T. africana, extending to the western Indian Ocean and east Africa. Tetraclita africana is reported from Madagascar and no further distribution record has been made apart from its type locality. Both species have pink parietes and are similar in size, which could lead to identification confusion. In this study, we revealed that T. africana differed from T. rufotincta in having multicuspidate setae on cirrus III, a feature that can be observed with both light microscopy and SEM. Additionally, the tergum of T. africana has a rounded spur and a larger basi-scutal angle than that of T. rufotincta. However, since the name Tetraclita africana has been pre-occupied under the name Tesseropora (Tetraclita) wireni africana Nilsson-Cantell, 1932, we, therefore, propose herein a replacement name, Tetraclita reni nom. nov. Based on museum specimens examined, Tetraclita reni nom. nov. is present in northeastern and southern Madagascar and Mauritius but absent from Yemen, Kenya, South Africa, Aldabra and northwestern Madagascar, suggesting the distribution of T. reni nom. nov. could be confined to the south and northeast of Madagascar and adjacent waters.
