According to the latest systematics the genus includes eight species with great karyotypic variation. Here, we studied karyotypes of 14 Calomyscus individuals from different regions of Iran and Turkmenistan using a new set of chromosome painting probes from a Calomyscus sp. male (2n = 46, XY; Shahr-e-Kord-Soreshjan-Cheshme Maiak Province). We showed the retention of large syntenic blocks in karyotypes of individuals with identical chromosome numbers. The only rearrangement (fusion 2\/21) differentiated Calomyscus elburzensis, Calomyscus mystax mystax, and Calomyscus sp. from Isfahan Province with 2n = 44 from karyotypes of C. bailwardi, Calomyscus sp. from Shahr-e-Kord, Chahar Mahal and Bakhtiari-Aloni, and Khuzestan-Izeh Provinces with 2n = 46. The individuals from Shahdad tunnel, Kerman Province with 2n = 51\u201352 demonstrated non-centric fissions of chromosomes 4, 5, and 6 of the 46-chromosomal form with the formation of separate small acrocentrics. A heteromorphic pair of chromosomes in a specimen with 2n = 51 resulted from a fusion of two autosomes. C-banding and chromomycin A3-DAPI staining after G-banding showed extensive heterochromatin variation between individuals.<\/jats:p>","DOI":"10.3390\/genes12070964","type":"journal-article","created":{"date-parts":[[2021,6,24]],"date-time":"2021-06-24T11:01:38Z","timestamp":1624532498000},"page":"964","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["New Data on Comparative Cytogenetics of the Mouse-Like Hamsters (Calomyscus Thomas, 1905) from Iran and Turkmenistan"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0951-5209","authenticated-orcid":false,"given":"Svetlana A.","family":"Romanenko","sequence":"first","affiliation":[{"name":"Institute of Molecular and Cellular Biology (IMCB), Siberian Branch of Russian Academy of Sciences (SB RAS), 630090 Novosibirsk, Russia"}]},{"given":"Vladimir G.","family":"Malikov","sequence":"additional","affiliation":[{"name":"Zoological Institute (ZIN), Russian Academy of Sciences (RAS), 199034 Saint-Petersburg, Russia"}]},{"given":"Ahmad","family":"Mahmoudi","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Science, Urmia University, Urmia 5756151818, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2889-4774","authenticated-orcid":false,"given":"Feodor N.","family":"Golenishchev","sequence":"additional","affiliation":[{"name":"Zoological Institute (ZIN), Russian Academy of Sciences (RAS), 199034 Saint-Petersburg, Russia"}]},{"given":"Natalya A.","family":"Lemskaya","sequence":"additional","affiliation":[{"name":"Institute of Molecular and Cellular Biology (IMCB), Siberian Branch of Russian Academy of Sciences (SB RAS), 630090 Novosibirsk, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1472-1613","authenticated-orcid":false,"given":"Jorge C.","family":"Pereira","sequence":"additional","affiliation":[{"name":"Animal and Veterinary Research Centre (CECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Cambridge Resource Centre for Comparative Genomics, Department of Veterinary Medicine, University of Cambridge, Cambridge CB3 OES, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0454-8359","authenticated-orcid":false,"given":"Vladimir A.","family":"Trifonov","sequence":"additional","affiliation":[{"name":"Institute of Molecular and Cellular Biology (IMCB), Siberian Branch of Russian Academy of Sciences (SB RAS), 630090 Novosibirsk, Russia"},{"name":"Department of Natural Science, Novosibirsk State University, 630090 Novosibirsk, Russia"}]},{"given":"Natalia A.","family":"Serdyukova","sequence":"additional","affiliation":[{"name":"Institute of Molecular and Cellular Biology (IMCB), Siberian Branch of Russian Academy of Sciences (SB RAS), 630090 Novosibirsk, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9372-1381","authenticated-orcid":false,"given":"Malcolm A.","family":"Ferguson-Smith","sequence":"additional","affiliation":[{"name":"Cambridge Resource Centre for Comparative Genomics, Department of Veterinary Medicine, University of Cambridge, Cambridge CB3 OES, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3200-4853","authenticated-orcid":false,"given":"Mansour","family":"Aliabadian","sequence":"additional","affiliation":[{"name":"Department of Biology, Faculty of Sciences, Ferdowsi University of Mashhad, Mashhad 9177948974, Iran"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8282-1085","authenticated-orcid":false,"given":"Alexander S.","family":"Graphodatsky","sequence":"additional","affiliation":[{"name":"Institute of Molecular and Cellular Biology (IMCB), Siberian Branch of Russian Academy of Sciences (SB RAS), 630090 Novosibirsk, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,24]]},"reference":[{"key":"ref_1","first-page":"350","article-title":"The principles of classification and a classification of Mammals","volume":"1","author":"Simpson","year":"1945","journal-title":"Bull.
