“…In the genus Muscari, most species are diploid, with a basic chromosome number of x=9 and a chromosome number of 2n=18 (Stuart, 1970, Karlén 1984b, Dalgıç 1991, Özhatay and Johnson 1996, Johnson and Brandham 1997, Demirci Kayıran and Özhatay 2017, Bozkurt 2020, Kiran et al 2020a. The current study confirms the former reports for all studied species.…”

“…In fact, taxonomic divisions within the genus were supported by karyological data by Garbari and Greuter (1970). Although most taxa of the genus are diploid, there are also some polyploid taxa (Stuart 1970, Karlén 1984b, Dalgıç 1991, Özhatay and Johnson 1996, Johnson and Brandham 1997, Demirci Kayıran and Özhatay 2017, Bozkurt 2020, Kiran et al 2020a. Chromosome number and chromosome morphology are increasingly used in plant taxonomy (Eroğlu et al 2013).…”

In this study, chromosome length, karyomorphology and chromosome asymmetry of six Turkish Muscari species; Muscari muglaensis, M. nazimiyensis, M. pallens, M. pamiryigidii, M. inundatum and M. fatmaceranie were evaluated. The somatic chromosome number of all examined taxa was determined as 2n=18. The basic chromosome number was x=9. Chromosomes consist of metacentric, submetacentric, and subtelocentric chromosomes. This is the first report on chromosome number and morphology for five of the six taxa studied. Studies on the karyotype and chromosomal diversity of Muscari may provide insight into taxonomic relationships and differences within the genus.

“…Metzgar et al (2016) reported that glaciation and associated climate shifts increased polyploidy rates. Demirci Kayıran and Özhatay (2017) reported that altitudes and high latitudes might have increased the polyploidy rates, although not always. All taxa have a distribution between 950 and 3260 m. High altitudes may have affected polyploidy levels, but this is not the only reason.…”

“…The majority of taxa have a basic number of x = 9 and have a high polyploidy ratio. Polyploidy originates from autopolyploidy by genome duplication in a species and allopolyploidy by genome duplication between species and has played a major role in the speciation and evolution of higher plants (Demirci Kayıran and Özhatay, 2017). Polyploidy may affect the speciation of subspecies.…”

Introduction Karyotype evolution can be constructed with chromosomal features based on size, shape, and number. Karyotypic differences are one of the most important mechanisms supporting speciation as they may create transitional barriers between species (Baltisberger and Hörandl, 2016). Therefore, chromosomal characters are used to elucidate phylogenetic relationships in plant cytotaxonomy. (Eroğlu et al., 2013; Eroğlu, 2015). These characters are basic number (x), diploid number (2n), chromosome length, relative length (RL), total haploid length (THL), centromeric index (CI), karyotype formula (KF), chromosome structure changes including deletions, inversions and translocations, chromosome number variations including dysploidy and polyploidy, karyotype asymmetry including symmetry/asymmetry index (S/A I), the coefficient of variation of chromosome length (CV CL), and mean centromeric asymmetry (

“…The B. brachyactis is the first polyploid species of the genus with a ploidy level of 4x. The polyploidy or genome duplication, originating from autopolyploidy and allopolyploidy, is one of the most effective mechanisms in speciation and karyotype evolution [24]. Polyploidy levels increase at high altitudes, although this is not the only reason.…”

Chromosomal data and karyological relationships provide valuable information about karyotype evolution and speciation. For the genus Bunium, the chromosomal data are limited. In the present study, the chromosomal data of 10 taxa are provided, 6 of which are given for the first time, 2 present new chromosome numbers, and 2 agree with previous reports. Four different chromosome numbers (2n=18, 20, 22 and 40) were detected, and 2n=40 is a new number in the genus Bunium. B. brachyactis is the first polyploid species of the genus with a ploidy level of 4x. The most asymmetric karyotypes are those of B. pinnatifolium and B. sayae. Regarding karyological relationships, B. pinnatifolium forms a monophyletic group by quite different karyological features such as large chromosomes, more submedian chromosomes and the most asymmetric karyotypes. In addition, the other 5 taxa form a strong monophyletic group. B. verruculosum and B. ferulaceum are cytotaxonomically very close species, as are B. sayae and B. elegans var. elegans. The chromosome numbers of 2 Turkish species, B. nudum and B. sivasicum, remain unknown. The presented results provide important contributions to the cytotaxonomy of Bunium.
