“…Such differences in basic chromosome numbers (x = 7 and x = 8) have been found in some other genera of Ranunculaceae, for example, Anemone L. and Ranunculus L. (Rice et al 2015). Our results regarding the chromosome numbers in E. sibirica (2n = 28 and 2n = 42) differed from the data reported by other researchers for this species (2n = 32: Krogulevich (1976) or 2n = 16: Gnutikov et al (2016Gnutikov et al ( , 2017). Eranthis tanhoensis was found to have 2n = 14.…”

At the same time, previous studies on E. sibirica reported 2n = 16 (Gnutikov et al 2016(Gnutikov et al , 2017 and 2n = 32 (Krogulevich 1976) chromosomes. However, the diploid plants described in these studies apparently refer to the recently described species E. tanhoensis.…”

“…The somatic chromosome number 2n = 2x = 16 has been reported in Eranthis in eight species from both sections: E. byunsanensis (Kim et al 2011), E. cilicica (Langlet 1932), E. hyemalis (Colasante and Ricci 1974;Tak and Wafai 1996;Gömürgen 1998;Caparelli et al 2007;Erst et al 2020a), E. lobulata (Erst et al 2019), E. longistipitata (Erst et al 2019), E. pinnatifida (Kurita 1955), E. sibirica (Gnutikov et al 2016(Gnutikov et al , 2017, and E. stellata (Yuan and Yang 2006). According to another study, E. stellata from Russian Far East would have somatic chromosome number 2n = 14 (Starodubtsev 1985), and this number was recently found in E. tanhoensis (Erst et al 2020b).…”

Comparative karyomorphological analyses of six out of the eight white-flowered species of Eranthis sect. Shibateranthis have been carried out. All studied specimens of E. byunsanensis, E. lobulata, E. pinnatifida, and E. stellata had a somatic chromosome number 2n = 16 with basic chromosome number x = 8. On the contrary, E. tanhoensis and E. sibirica had a basic chromosome number x = 7. The specimens of E. tanhoensis were diploid with 2n = 14, while the specimens of E. sibirica were polyploid with 2n = 42. Monoploid chromosome sets of the investigated diploid species had 4–5 metacentric chromosomes and 2–4 submetacentric/subtelocentric/acrocentric chromosomes. The highest level of interchromosomal asymmetry, estimated via CVCL, was found in E. byunsanensis and E. pinnatifida. The highest levels of intrachromosomal asymmetry (MCA) and heterogeneity in centromere position (CVCI) were found in E. lobulata and E. byunsanensis, while E. sibirica had the most symmetric karyotype. A multivariate PCoA analysis of basic karyotype parameters (2n, x, THL, CVCL, MCA, and CVCI) highlighted no overlap among species accessions, which was also confirmed by LDA. The average absolute monoploid DNA content (1Cx) of the 23 investigated samples of six Eranthis species varied from 9.26 ± 0.25 pg in E. sibirica to 15.93 ± 0.32 pg in E. stellata. Overall karyological affinity was highlighted between E. lobulata and E. stellata, on one side, and between E. byunsanensis and E. pinnatifida, on the other side. Interestingly, there was no significant correlation between total haploid (monoploid) chromosome length (THL) and 1Cx values in these species.

“…The count n = 36, 2n = 72(Clausen 1927) is an error recognized by the author(Clausen 1931a). Finally, odd counts 2n = 24, 48 from [IRK](Probatova et al 2016b) are hard to explain because never found in the subg. Viola; they correspond perhaps to a confusion with species of sect.…”

This study proposes a revision of the genus Viola L. (Violaceae) in the Russian Far East and adjacent regions. It is based on the taxonomic work that Becker conducted on the Asian Viola (1915)(1916)(1917)(1918)(1919)(1920)(1921)(1922)(1923)(1924)(1925)(1926)(1927)(1928), but also on Clausen's cytotaxonomic studies that laid the foundations of the genus' phylogeny. Chromosome counts, as well as phylogenetic analyses, have allowed to specify the infrageneric taxonomy and establish relationships between some taxa of American or Asian adjacent territories. A systematic treatment based on the Biological Species Concept, associated with genetic, cytotaxonomic, and biogeographic data, allowed many systematic and nomenclatural changes, at different levels: infrageneric, specific and infraspecific. This study shows the remarkable role of the Russian Far East for the conservation and differentiation of the genus Viola species, and probably for the whole flora of the Holarctic Kingdom.

(Violaceae) Дальнего Востока России с замечениями для сопредельных территорий. В данном исследовании пред лагается ревизия рода Viola L. (Violaceae) на Дальнем Востоке России и в прилегающих регионах. Он основан на таксономической работе Беккера по азиатским фиалкам (1915)(1916)(1917)(1918)(1919)(1920)(1921)(1922)(1923)(1924)(1925)(1926)(1927)(1928), а также на цитотаксономических исследованиях Клаузена (1926-1964), которые заложили основы филогении рода. Подсчет хромосом, а также филогенетический анализ позволили уточнить таксономию внутри рода и установить взаимосвязь между некоторыми таксонами с прилегающих территорий Америки и Азии. Систематика, основанная на биологической концепции вида, связанная с генетическими, цитотаксономическими и биогеографическими данными, позволила провести большое число систематических и номенклатурных изменений на разных уровнях: внутриродовом, видовом и внутривидовом. Исследование показывает заметную роль российского Дальнего Востока в сохранении и дифференциации видов рода Viola и, вероятно, для всей флоры Голарктического 4
