The article considers the genetic mechanisms of plant speciation. The importance of interspecific hybridization and polyploidy (whole genome duplication, WGD) as the main mechanisms of plant speciation is shown. There are three main ways of transformations of the hybrid genome associated with speciation. In the first way, the ploidy of the offspring does not change in comparison with the parents’ ploidy; the genomes of hybrid lines are stabilized through backcrosses and introgression without polyploidization. In the second way, the interspecial hybridization followed by whole genome duplication. Then, the initially unstable neopolyploid genome gradually passes into a stable eupolyploid state with the preservation of the polyploid number of chromosomes but with the diploid type of chromosome conjugation in meiosis. This is a widespread and rapid mechanism of plant speciation and genus formation in higher plants, which ensured the morphological and genetic isolation and adaptability of at least 15 % of modern species of higher plants. However, this is a path that usually does not lead to aromorphoses, this is speciation at an already achieved level of complexity. The third way of speciation is realized through dysploidy and secondary diploidization of the genome. In this case, the neopolyploid undergoes significant genomic rearrangements and loses most of the duplicated gene copies, its number of chromosomes is radically reduced. In different individuals of a species that has embarked on the path of stochastic genome fractionation and dysploidy, the initial genetic redundancy of various genome components multiplied after WGD is transformed in an unpredictably unique way, which leads to a radical increase in intraspecific genomic and epigenetic polymorphism and provides rich material for natural selection. It was also shown that in eupolyploids and paleopolyploids, a significant role in heritable adaptations to environmental conditions and in anatomical and morphological innovations is played by segment and tandem duplications not associated with WGD. Some of the paleopolyploids, which turned out to be evolutionarily progressive morphotypes, possessing aromorphoses with diploidized genomes, give rise to new phylogenetic branches, new suprageneric taxa. The article proposes to assign both genera carrying a unique two-chromosomal genome Zingeria and Colpodium (x = 2; 2n = 4, 8, 12) into subtribe Zingeriinae Rodionov, subtrib. nov. – Type: Zingeria P. A. Smirn. In addition, the accomodation of the genera Helictochloa and Molineriella into one subtribe Helictochloinae Röser et Tkach seems to us unreasonable from a genomic point of view, since the fundamental difference between representatives of these two genera is that Molineriella species carry an unusual 4-chromosomal genome, while speciation in genus Helictochloa(2n = 14 – 154) goes through the combinations of different 7-chromosome subgenomes, denoted by the letters E, L, B, C, M, V, G, U.

The article deals with the problem of nomenclature and classification of phytoliths. The division of the “crenate” morphotype (ICPN 2.0) into two forms – polylobate and wavy – is substantiated using Pooideae grasses from the south of Western Siberia. An analysis of the literature data confirms the heterogeneity of this morphotype and various interpretations of its variations. The polylobate group includes phytoliths high in lateral projection with distinct lobes, and the wavy group includes flattened forms with a wavy edge. The article details the formation of these two morphotypes in 52 grass species belonging to 25 genera. The main content of the study is an analysis of the occurrence of forms in various tribes and subtribes according to modern information on the phylogeny of cereals. The differences in the formation of these morphotypes at the sectional and subgeneric levels are considered using as examples three genera. The detailed analysis shows that wavy plates are most typical for the subtribe Aveninae(Poeae), polylobed particles are typical for the subtribe Agrostidinae (Poeae) and the tribe Meliceae. For some taxa, for example, the tribe Stipeae, ambiguous data have been obtained that are inconsistent with information from other territories, which indicates the need for further research on this problem. The analysis of occurrence of forms at the intrageneric level shows that in the genera Poa and Festuca there are differences between individual subgenera and sections, while for the genus Calamagrostis there are no such differences. The results obtained point to the prospect of using phylogenetic information in the classification of phytoliths and the need for a more complete study of large genera of grasses in terms of phytolith composition (Festuca, Calamagrostis, Poa, Stipa, etc.).

Taxonomy, nomenclature, morphology, and distribution of Campanula farinosa are updated. The species is for the first time reported for Ural and Western Siberia; C. krylovii is relegated to its synonymy. Morphological characters discriminating C. farinosa and C. glomerata are revised; stability of these features throughout the whole area of C. farinosa ranging from Central Europe to Western Siberia is underlined as an argument favoring the species (not subspecies) status of the latter.

This article analyzes the materials of the “Set of additions and changes to the check-list of the flora of the Republic of Buryatia from 2001 to 2020”. Corrections and comments are given on 50 species of higher vascular plants, both erroneously cited as novelties, and, on the contrary, absent from the original publication, regarding the territory of the Baikalsky State Nature Reserve and its buffer zone. Two taxa amongst omitted in the source material are included in the Red Data Book of the Russian Federation (Aconitum paskoi subsp. arcto-alpinum and Asplenium sajanense), and 10 species are alien for the flora of Buryatia (Achillea ptarmica, Alchemilla baltica, Atriplex sagittata, Carthamus tinctorius, Centaurea phrygia, Convolvulus inflata, Epilobium tetragonum, Persicaria maculosa, Setaria pumila, Sorghum halepense). Several plant species actually were firstly recorded for Buryatia earlier than the period from 2001 to 2020 or have been already known for this territory much earlier; Rhynchospora alba is one of such species, and it is included in the all the editions of the Red Data Books of the Republic of Buryatia. In some cases of references to early indications and herbarium collections, modern ideas about the taxonomy of groups and ranges of species are considered for clarification.

The features of pubescence of mericarps in 34 taxa of species and intraspecific ranks of the genus Geranium from different sections were studied. Based on the studied materials, a classification of trichomes on the surface of mericarps has been developed. Two groups of trichomes have been distinguished: non-glandular, including three types and six subtypes, and glandular, including one type and four subtypes. For the first time, non-glandular simple unbranched ribbon-like trichomes (LP), non-glandular complex uniserial unbranched hooked trichomes (CrS), non-glandular complex uniserial unbranched helical trichomes (BC), non-glandular complex uniserial branched filamentous arachnoid trichomes (PS), long glandular capitate unbranched complex trichomes with big head (GLb). The types of mericarp trichomes were analyzed according to their occurrence in different sections of the genus Geranium. It has been shown that there are types of trichomes that are characteristic of the mericarps of the species of most sections, and types of trichomes that are characteristic of the mericarps of species of one or two sections, or even one species from the sections. This is the basis for considering some characters of trichomes as a specific and sectional characters. At the same time, this issue requires further study of the surface of mericarps of representatives of other species, both from the already studied sections and from new sections.

Its reports from the Orel Region were based on the incorrectly determined herbarium specimens of other taxa. Reports from the Bryansk Region although not confirmed by herbarium specimens are also obviously erroneous as evidenced by their collection date.

Allium pallasii Murr. var. nitidulum Fisch. et Regel was assigned species status (A. nitidulum Fisch.) in 1853 by Ledebour in “Flora Rossica”, being considered as a synonym of Allium pallasii but with no description. Then in 1887 E. Regel considered it as a variety: “Allium pallasii Murr. ß nitidulum teste Rgl.” and highlighted its morphological differences, referring to a certain number of herbarium specimens. Herbarium specimens ofAllium pallasii Murr. var. nitidulum Fisch. et Regel which have annotations made by F. B. Fischer, K. F. Ledebour, E. L. Regel and A. I. Schrenk are currently kept in the collections of the Herbarium of the Komarov Botanical Institute of the Russian Academy of Sciences (LE). The identification of the material that Ledebour and Regel studied gave us the opportunity to choose a lectotype and a series of specimena authentica of this variety.

Then in 1887 E. Regel considered it as a variety: “Allium pallasii Murr. ß nitidulum teste Rgl.” and highlighted its morphological differences, referring to a certain number of herbarium specimens. Herbarium specimens ofAllium pallasii Murr. var. nitidulum Fisch. et Regel which have annotations made by F. B. Fischer, K. F. Ledebour, E. L. Regel and A. I. Schrenk are currently kept in the collections of the Herbarium of the Komarov Botanical Institute of the Russian Academy of Sciences (LE). The identification of the material that Ledebour and Regel studied gave us the opportunity to choose a lectotype and a series of specimena authentica of this variety.","PeriodicalId":45595,"journal":{"name":"Turczaninowia","volume":" 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41252244","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}
