This article presents the results of cytogenetic analysis of the Pinus sylvestris L. seed progeny from 5 populations growing in the boreal forests of the European North of Russia (Republic of Karelia). Based on the study of plants karyotype, it was found that in addition to diploid cells some seedlings contained single tetraploid and aneuploid cells. Mainly, mixoploid plants were found in Sheltozerskoye and Ambarnskoye forest divisions. It is important to note that these populations were characterized by high values of such indicators as the frequency of mitotic pathologies at the metaphase and ana-telophase stages (5.3 ± 0.6 and 7.1 ± 0.6 % respectively), as well as the proportion of cells with micronuclei (0.2 ± 0.06 and 0.1 ± 0.04 % respectively) in the root meristem of Pinus sylvestris. However, despite data received, seeds from Sheltozersky and Ambarnsky forest divisions had high germination values. Nine types of chromosome aberrations were found due to the analysis: fragmentation, bridges, ring chromosomes, lagging, chromosome leading, isolation, multipolar and chaotic chromosome divergence, complex (multiple) disorders. In most of the seedlings studied, the most common pathology was chromosome overrun. In addition, the study showed that bridges proportion in the total disturbances’ spectrum at the ana-telophase stages of mitosis increases by ~ 3.5 times in Pinus sylvestris populations growing in the northern taiga subzone compared to the middle taiga populations. In most of the seedlings studied, the most common pathology was chromosome overrun. Thus, the use of a cytogenetic test made it possible to evaluate the state of Pinus sylvestris genome from different populations in the European North of Russia and to identify responses aimed at plant adaptation to environmental conditions at the cellular level.

A review of both classes of flowering plants in the system of A. L. Takhtajan (1987) showed a general picture of the distribution of xerophytic phyla and groups in the Earth floras. The xerophilic lines of development in flowering plants are very ancient, and there are more of them among dicots than monocots. Xerophytic groups are more diverse in the floras of the Southern (compared to the Northern) Hemisphere, where the main centers of development of xerophilic floras are in South America, South Africa, and Australia. At the same time, New World xerophilic floras differ from Old World ones in the presence of a larger number of endemic families. The xerophytic centers of the Northern Hemisphere are in the tropics and subtropics, both in the Old and New Worlds: Africa, Arabia, India, the Mediterranean, North America (Madrean sub-kingdom).

New data on the distribution of 40 species from the families Asteraceae, Cystopteridaceae, Dryopteridaceae, Euphorbiaceae, Poaceae, Rosaceae, and Woodsiaceae in Mongolia are presented in the article. For the first time, Centaurea cyanus, Cystopteris almaatensis, Potentilla × habievii, Potentilla salsa, and Potentilla smirnovii are indicated for the flora of the country. 19 species previously known in the flora of Mongolia are new for its separate botanical and geographical regions. Of these, 7 taxa were found for the first time in the Khuvsgul, 5 – in the Khovd, 4 – in the Gobi Altai and 3 – in the Mongolian Altai regions, 2 each – in the Khangai, Khentei, and Dzungarian Gobi, 1 – in the Middle Khalkha. New locations were registered for 19 rare and endemic species of the study region. There are narrow local national endemics: Potentilla coriacea, P. inopinata, P. laevipes, and P. schmakovii, among them. The findings are divided into three groups in the article. Comments about the range, relationships and main morphological differences are given for each species. Photographic materials of Potentilla salsa made in nature on the territory of Mongolia are demonstrated for the first time.

Selaginella submonospora is described as a new species from western Yunnan (China) based on morphological and molecular evidence. It is morphologically similar to S. subdiaphana (Wall. ex Hook. et Grev.) Spring, S. monosporaSpring, and S. hezhangensis P. S. Wang et X. Y. Wang. Selaginella submonospora can be distinguished by its leaves with short denticulate-ciliolate margins, dorsal leaves obliquely subcordate at base, short acuminate at apices, and ventral leaf oblique at base. Furthermore, the phylogenetic analysis based on the concatenated chloroplast genes rbcL, atpI, and psbA supported that S. submonospora is a distinct species and closely related to S. monospora.

Based on the study of collections of LE, RV and RWBG, information on occurrence (or absence) of certain Cruciferae (Brassicaceae) species in Russia and some neighbouring states is updated. Camelina hispida is first recorded from Russia, Camelina sativa from Turkmenistan and Goldbachia torulosa from Ukraine as alien species apparently not naturalized in relevant countries. In contrast, Isatis armena, a novelty for the flora of both Russia and Europe, along with Plagioloba persica for the first time recorded from Kyrgyzstan, appears to be aboriginal elements in the newly revealed localities. At the same time, occurrence of Isatis cardiocarpa in Europe, as well as an introduction ofGoldbachia laevigata in Ukraine does not get support. In addition, the combination Plagioloba perfoliata is validated.

Seed morphology and ultrastructure of Lotus species from sections Dorycnium (L. dorycnium and L. graecus), Bonjeanea (L. rectus, L. hirsutusand L. strictus) and Lotus (L. corniculatus) have been studied using light and scanning electron microscopy. The seeds of studied species have a conservative structure typical for most Papilionoideae. Seed size, shape and color only partially allow distinguishing species in the studied group. The most morphologically distinguishable seeds are those of members of the polyphyletic section Bonjeanea, with L. rectus having the smallest and L. strictus the largest seeds. Seed size ranges in the species of the section Dorycnium overlap both between the members of the section and with seeds of L. hirsutus (section Bonjeanea). Seed surface ultrastructure around the hilum is very stable among studied species, whereas that on the lateral seed side is more variable. The types of surface sculpture on the lateral seed side do not strongly correlate with taxonomic position of species, but some correlations with eco-geographical patterns can be traced. The type of seed surface micromorphology with inconspicuous primary sculpture and thick secondary cuticular deposits was revealed in taxa, which distribution is connected with the Mediterranean region (L. hirsutus, L. dorycnium subsp. gracilis and partially L. rectus). Foveolate-papillose primary sculpture with thin secondary cuticular deposits is typical for species occurring in milder climate (L. corniculatus, L. strictus, L. graecus). Studied species can be subdivided into two groups by endosperm thickness. We believe that thin endosperm revealed in L. strictus and L. corniculatus may be a trait connected with the acceleration of development when spreading from the Mediterranean to the temperate climatic zone.

Seed size ranges in the species of the section Dorycnium overlap both between the members of the section and with seeds of L. hirsutus (section Bonjeanea). Seed surface ultrastructure around the hilum is very stable among studied species, whereas that on the lateral seed side is more variable. The types of surface sculpture on the lateral seed side do not strongly correlate with taxonomic position of species, but some correlations with eco-geographical patterns can be traced. The type of seed surface micromorphology with inconspicuous primary sculpture and thick secondary cuticular deposits was revealed in taxa, which distribution is connected with the Mediterranean region (L. hirsutus, L. dorycnium subsp. gracilis and partially L. rectus). Foveolate-papillose primary sculpture with thin secondary cuticular deposits is typical for species occurring in milder climate (L. corniculatus, L. strictus, L. graecus). Studied species can be subdivided into two groups by endosperm thickness. We believe that thin endosperm revealed in L. strictus and L. corniculatus may be a trait connected with the acceleration of development when spreading from the Mediterranean to the temperate climatic zone.","PeriodicalId":45595,"journal":{"name":"Turczaninowia","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48863483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
