“…The population in the foothills of Tarbagatai is the most extensive and is included in the Red Book of Kazakhstan ( Stepanova, 1962 ; Baitulin, 2014 ). Natural populations of P. ledebouriana are declining due to habitat degradation, frequent droughts, changes in the fire regime (succession), overgrazing, and urbanization ( Sumbembaev, 2018 ; Sumbembayev et al, 2021 ; Aidarkhanova et al, 2022 ; Kusmangazinov et al, 2023 ). Therefore, by the Decree of the Government of the Republic of Kazakhstan in 2018, the Tarbagatai State National Natural Park (East Kazakhstan region, Urdzhar district) was adopted and the preservation of this rare and endangered species was recommended ( Republic of Kazakhstan, 2018 ).…”

Background Genetic differences between isolated endemic populations of plant species and those with widely known twin species are relevant for conserving the biological diversity of our planet’s flora. Prunus ledebouriana (Schlecht.) YY Yao is an endangered and endemic species of shrub almond from central Asia. Few studies have explored this species, which is closely related and morphologically similar to the well-known Prunus tenella Batsch. In this article, we present a comparative analysis of studies of three P. ledebouriana populations and one close population of P. tenella in Eastern Kazakhstan in order to determine the particular geographic mutual replacement of the two species. Methods The populations were collected from different ecological niches, including one steppe population near Ust-Kamenogorsk (P. tenella) and three populations (P. ledebouriana) in the mountainous area. Estimation of plant height using a t-test suggested a statistically significant difference between the populations and the two species (P < 0.0001). DNA simple sequence repeat (SSR) markers were applied to study the two species’ genetic diversity and population structure. Results A total of 19 polymorphic SSR loci were analyzed, and the results showed that the population collected in mountainous areas had a lower variation level than steppe populations. The highest level of Nei’s genetic diversity index was demonstrated in the 4-UK population (0.622) of P. tenella. The lowest was recorded in population 3-KA (0.461) of P. ledebouriana, collected at the highest altitude of the four populations (2,086 meters above sea level). The total genetic variation of P. ledebouriana was distributed 73% within populations and 27% between populations. STRUCTURE results showed that two morphologically similar species diverged starting at step K = 3, with limited population mixing. The results confirmed the morphological and genetic differences between P. tenella and P. ledebouriana and described the level of genetic variation for P. ledebouriana. The study’s results proved that the steppe zone and mountain altitude factor between P. tenella and isolated mountain samples of P. ledebouriana.

Critical processing of herbarium materials revealed the distribution in Kazakhstan of 10 species of the genus Rheum, including Rheum compactum L., R. wittrokii Lundstr., which are classified as rare and declining in number. R. altaicum Losinsk. was discovered – relict and endemic of Altai. To clarify the distribution in Kazakhstan and compile a summary of species of the genus Rheum, 143 herbarium sheets (1840 – 2024) from the Altai Botanical Garden (ABG), Institute of Botany (AA), and the digital herbarium of Moscow State University (MW) were reviewed and processed. 253 actual places of growth were identified for 10 species of rhubarb from the flora of Kazakhstan, belonging to 5 sections: Rhapontica A. Los., Deserticola Maxim., Orbicularia A. Los., Spiciformia A. Los., Ribesiformia A. Los. A high species diversity of rhubarb was established in the Dzungarian Alatau, Altai, Tarbagatai and Ile Kungei Alatau. Geographically, the most widespread are R. tataricum, R. nanum and R. wittrockii. The research made it possible to systematize, clarify and supplement information on the species diversity and distribution of the genus Rheum in the flora of Kazakhstan.

“…Due to the polymorphic nature of the hawthorn, there are two interpretations of its species. In several works, the name C. ambigua is retained for the Mangyshlak hawthorn [ 21 ], while other authors [ 22 , 23 , 24 , 25 ] recognise it as an independent species of C. trancaspica (the trans-Caspian hawthorn). This plant grows mainly along the bottom of ravines, chalk, and gypsum gorges and in damp places.…”

This article studies the morphological parameters of vegetative and generative organs of different age groups of Crataegus ambigua from four populations in Western Karatau (Mangistau region, Kazakhstan). In this study, we examined four populations: Sultan Epe, Karakozaiym, Emdikorgan, and Samal, all located in various gorges of Western Karatau. Several phylogenetic inference methods were applied, using six genetic markers to reconstruct the evolutionary relationships between these populations: atpF–atpH, internal transcribed spacer (ITS), matK, psbK–psbI, rbcL, and trnH–psbA. We also used a statistical analysis of plants’ vegetative and generative organs for three age groups (virgin, young, and adult generative). According to the age structure, Samal has a high concentration of young generative plants (42.3%) and adult generative plants (30.9%). Morphological analysis showed the significance of the parameters of the generative organs and separated the Samal population into a separate group according to the primary principal component analysis (PCoA) coordinates. The results of the floristic analysis showed that the Samal populations have a high concentration of species diversity. Comparative dendrograms using UPGMA (unweighted pair group method with arithmetic mean) showed that information gleaned from genetic markers and the psbK–psbI region can be used to determine the difference between the fourth Samal population and the other three.
