“…Moreover, we detected 0-2 B chromosomes in karyotypes of S. officinalis. These supernumerary chromosomes were revealed earlier in several Salvia species including S. sclarea and S. officinalis [21][22][23][24]. B chromosomes are found in many eukaryotic organisms.…”

“…In the genus Salvia, various chromosome numbers were detected (x = 6, 7, 8, 9, 11; 13; 15; 17; and 19) but the most common basic chromosome numbers were x = 7, x = 8, and x = 11. [23,26,43]. Currently, the ancestral basic number is considered to be x = 7 [16,89].…”

“…For a number of Salvia species, polyploid populations were revealed along with diploid ones [16,20]. In karyotypes of S. sclarea, S. nemorosa, S. farinacea, S. reuterana, and S. officinalis, 0-2 supernumerary B chromosomes were detected [21][22][23][24]. The relationship revealed between geographical distribution, chromosome numbers, and ploidy levels indicates that both aneuploidy and polyploidy played an important role in the speciation processes within Salvia [16,20].…”

Within the complicated and controversial taxonomy of cosmopolitan genus Salvia L. (Lamiaceae) are valuable species Salvia officinalis L. and Salvia sclarea L., which are important for the pharmaceutical, ornamental horticulture, food, and perfume industries. Genome organization and chromosome structure of these essential oil species remain insufficiently studied. For the first time, the comparative repeatome analysis of S. officinalis and S. sclarea was performed using the obtained NGS data, RepeatExplorer/TAREAN pipelines and FISH-based chromosome mapping of the revealed satellite DNA families (satDNAs). In repeatomes of these species, LTR retrotransposons made up the majority of their repetitive DNA. Interspecific variations in genome abundance of Class I and Class II transposable elements, ribosomal DNA, and satellite DNA were revealed. Four (S. sclarea) and twelve (S. officinalis) putative satDNAs were identified. Based on patterns of chromosomal distribution of 45S rDNA; 5S rDNA and the revealed satDNAs, karyograms of S. officinalis and S. sclarea were constructed. Promising satDNAs which can be further used as chromosome markers to assess inter- and intraspecific chromosome variability in Salvia karyotypes were determined. The specific localization of homologous satDNA and 45S rDNA on chromosomes of the studied Salvia species confirmed their common origin, which is consistent with previously reported molecular phylogenetic data.

“…The chromosomal variations change the centromere position and the morphology of chromosome and affect the karyotype asymmetry. For this reason, the karyotype asymmetry is one of the most important parameters supporting the morphological characters [1][2][3][4].…”

The family Canidae is placed in the suborder Caniformia in the order Carnivora. There are both domestic and wild species in Canidae. The family consists of at least 35 wild species in 13 genera. The number of chromosomes in Canidae is divided into 2 groups. (i) The chromosome numbers are 2n = 54, 66, 74, 76, and 78 with mostly acrocentric autosomes. (ii) The chromosome numbers are 2n = 34, 36, 38, and 50 with mostly metacentric and submetacentric autosomes. The formula S/AI measure the symmetry or asymmetry of karyotype in higher animals and humans. In this study, the formula was applied to the Canidae species. After obtaining karyotype formulae with a detailed literature review, S/AI data and karyotype types of 25 female taxa and 17 male taxa were determined. According to the S/AI values, a dendrogram was drawn showing karyological variations among the taxa. The results will contribute to the phylogeny of mammals.

“…Сравнительный анализ репитомов двух ценных эфиромасличных видов, S. officinalis и S. sclarea L. с использованием данных высокопроизводительного секвенирования позволил провести картирование выявленных повторов (семейств) сателлитной ДНК (сатДНК) на хромосомах с помощью процедуры FISH (флуоресцентная гибридизация in situ) и впервые провести идентификацию хромосом в кариотипах этих видов (Muravenko et al, 2022). У ряда видов рода Salvia обнаружена межпопуляционная изменчивость числа хромосом, диплоидные и полиплоидные популяции, а также выявлены В-хромосомы в кариотипах (Tarinejad, Mirshekari, 2010;Eroğlu et al, 2021;Martin et al, 2022). Считается, что анеуплоидия и полиплоидия могут играть важную роль в процессах видообразования (Ranjbar et al, 2015;Eroğlu et al, 2021).…”

Salvia officinalis L. (Lamiaceae) is a widespread economically valuable species. Due to the high content of essential oil, it is actively used in pharmaceutical, food and perfume industries. However, the chromosome structure and organization of its genome is still not well understood. For the first time, an analysis of intraspecific variability of S. officinalis was carried out based on the patterns of FISH localization of various DNA repeats in karyotypes of four species samples and two varieties from different habitats. Patterns of chromosome localization on of classical markers, 45S rDNA and 5S rDNA, confirmed the stability of genomes of the studied species samples and varieties. However, the intraspecific variability in localization of SO202 in karyotypes of the studied samples was found. In addition to the main set of chromosomes, B chromosomes were found in some karyotypes, including those containing 45S rDNA and SO202 clusters. The results of this study allowed us to identify all chromosome pairs in karyotypes and construct karyograms of the studied samples of S. officinalis. Our findings confirmed the stability of karyotypes of these samples according to the classical chromosomal markers but also demonstrated the presence of intraspecific variability in localization of the SO202 repeat, which can be used in breeding new varieties of S. officinalis.
