“…Most of them concern various issues more or less associated with the problem of Dutch elm disease (DED) epidemics (e.g., [6][7][8][9][10][11][12]). Further on, there are publications on ecophysiology and recently also genetics [13][14][15]. There is a shortage of publications on the quantitative contribution of individual species to forest stands in a given area.…”

In nearly 600 randomly selected forest stands including elms (Ulmus spp.), we conducted field research to identify them to species level and to find trees showing symptoms of Dutch elm disease (DED). The presented data show that all the 3 native elms (U. glabra, U. laevis, and U. minor) still exist in the whole ranges of their distribution in Poland reported earlier, but their role as forest-forming species has changed. In comparison to published data, the contribution of U. minor has markedly decreased, while an increased contribution was observed in the case of U. laevis, a species which in the past was predominantly located out of woodland and was rarely cultivated. In mountains, where the most frequent is U. glabra, the contribution of elms to forest stands is currently clearly lower than in the lowlands and uplands of Poland. The observed changes most probably result from Dutch elm disease. It cannot be excluded that the changes are at least partly linked with natural correction of forest stand composition modified earlier by human activity (silviculture). In all parts of Poland, trees with symptoms of Dutch elm disease are found, but large-scale decline (of a majority of elm trees) is observed only in about 1.5% of the directly investigated localities.

“…Для M. alba інформаційний індекс Шеннона за ТВР склав 0,44, що вище у два рази відносно рівня оцінок отриманих за іншими (SRAP) маркерами для цього виду (I = 0,22) [24]. Для U. glabra значення РІС, оцінене за допомогою ТВР маркерів, знаходиться на рівні оцінок поліморфізму отриманих за SSR маркерами (РІС = 0,141-0,899) у представників цього виду Іберійського півострова [25].…”

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.

“…Слід зазначити, що рівень поліморфізму, оцінений за 15 мікросателітними локусами у 53 дерев U. pumila з Китаю, виявився дещо вищим (Aе = 1,89, I = 0,56, He = 0,27) [5], але для даного дослідження не вказано вік аналізованих дерев. Для популяцій U. glabra Huds., що зростають у сприятливих умовах Іберійського півострова поліморфізм за 22 локусами також виявився вищим (Ne = 1,711-2,803, I = 0,547-1,047, He = 0,310-0,590) [29]. Той факт, що отримані в даному дослідженні оцінки нижчі порівняно із рівнем генетичного різноманіття в вибірках Степового Придніпров'я, можна пояснити віком аналізованих рослин.…”

Aim. Using DNA markers related to the genes encoding β-tubulin in plants, to evaluate the intraspecific genetic polymorphism of Ulmus pumila L. in the Steppe Prydniprov'yia and compare it with the polymorphism of this species within the natural range. Method. Analysis of the intron length of polymorphism of β-tubulin genes (TBPmethod). Results. It was established that the plants differ from each other slightly in terms of the number of identified amplicons and the nature of their distribution when comparing electrophoretic profiles obtained on the basis of the TBP analysis for U. pumila. Half of the fragments found in the samples are rare. The average number of fragments (alleles) on the locus (Ne), Shannon information index (I) and polymorphism information content value (PIC) amounted respectively: 1.26, 0.27, 0.21, and were lower than in natural populations, analyzed using microsatellite markers. Conclusions. U. pumila plants growing in the Steppe Prydniprov'yi for the TBP markers have a lower level of genetic diversity than was found during the analysis of natural populations using other molecular markers. Among the possible reasons may be the nature (methodology) of the creation and age of the tree stands examined, as well as the nature of the genetic markers used to analyze the genetic polymorphism of the species.Keywords: TBP-method, introns, β-tubulin, Ulmus pumila, genetic diversity.
