“…(Asteraceae) contains about 250 perennial, biennial or rarely annual and spiny species (Zomlefer 1994;Bureš et al 2004). These species mainly grow in Northern hemisphere, Europe, North Africa, Siberia, central Asia, west & east Africa and Central America.…”

“…They show wide range of ecological adaptations in places they grow and occupy different localities with regard to elevation, temperature and edaphic factors due to their genetic adaptability and plasticity. They also are well known for interspecific hybrid formation and wide gene flow, which also helps their adaptation to various environmental conditions (Bureš et al 2004). Such features have resulted in the extensive variation in morphological characters observed in Cirsium taxa.…”

Genetic diversity and population structure in four Cirsium (Asteraceae) species

et al. 2013

The present study considers genetic diversity of 38 populations in 4 Cirsium species of the genus Cirsium Mill. (Asteraceae), occurring in different ecological regions and tries to compare degree of genetic variability among the species with wide geographical distribution versus endemic C. pyramidale showing confined geographical distribution. The results showed that the endemic species has similar value of genetic diversity parameters as the species with wider distribution. We also studied the possible admixture nature of these populations and tried to understand the relation between genetic changes, geographical distribution and polyploidy level and chromosome pairing in these species. ISSR analysis showed population difference in allele composition and frequency. Clustering and PcoA ordination produced different groupings in each species, while STRUCTURE and reticulation analyses revealed high degree of genetic admixture and gene exchange among populations as well as allelic rearrangement. No significant correlation was observed between geographical distance and genetic distance of the populations and AMOVA test revealed no significant difference among populations in each species studied. However, high amount of within population variation occurred in all 4 species indicating their cross-pollination nature and high genetic admixture. The populations also varied in chiasma frequency and chromosome pairing as well as the occurrence of heterozygote translocations all creating more variability to be used by plants for local adaptation.

“…For example, Price et al (1983) showed that DNA content differed significantly between Microseris F 1 hybrids and those of their parental species, and Bureš et al (2004) found that the DNA values of most interspecific hybrids of Cirsium were between those of their putative parents. Three Helianthus hybrid species showed a marked increase in DNA content as compared with the parental species (Baack et al, 2005).…”

Hybridization may induce rapid genomic changes, including gain or loss of DNA. We examined nuclear DNA content of a diploid hybrid species, Hippophae goniocarpa and its two parental species. The nuclear 2C DNA value was 2.95±0.08 pg for H. goniocarpa; for the parental species it ranged from 2.54±0.09 pg to 2.66±0.12 pg for H. rhamnoides ssp. sinensis and from 3.15±0.19 pg to 3.49±0.06 pg for H. neurocarpa ssp. neurocarpa. The nuclear DNA content of H. goniocarpa was intermediate between those of the two parental species, confirming that this species is of diploid hybrid origin and further suggesting that it is in an early stage of the process of speciation.K Ke ey y w wo or rd ds s: : Nuclear DNA content, flow cytometry, H. goniocarpa, hybrid species, interspecific and intraspecific variation.

“…10%). Several chromosome numbers such as 2n = 16, 18, 20, 22, 24, 26, 28, 26, 51, and 102 are either very rare or doubtful (Bures et al, 2004). In addition, 2n = 32, 34, 36, 60, and 68 chromosome numbers were reported from studies on the Turkish Cirsium taxa (Ozcan et al, 2008(Ozcan et al, , 2011Yüksel et al, 2013).…”

The name Cirsium originates from the Greek word "khirsos", which means "swollen vein", referring to diseases of veins. Tournefort, citing Dioscorides, reported that the roots of this plant were used against diseases of veins. In addition, the use of this plant in varicose disease for pain relief was reported (Tournefort, 1694;Charadze, 1963). The name Cirsium was used by botanists in the pre-Linnean period (Bauhin, 1596; Tournefort, 1694). In Species Plantarum, the species of the genus Cirsium were treated given under the names of the genera of Serratula L., Carduus L., and Cnicus L. by Linnaeus (1753).The history of the genus Cirsium is given below chronologically in terms of taxonomy:The first comprehensive study was carried out in "Prodramus Sytematis Naturalis" by Candolle (1838). In this study, the genus was represented by 137 species belonging to 6 sections: C. sect. Lophiolepis Cass. (4 species), C. sect. Eriolepis Cass. (38 species), C. sect. Orthocentron Cass. (6 species), C. sect. Corynotrichum DC. (3 species), C. sect. Cephalonoplos (Necker) DC. (5 species), and C. sect. Onotrophe Cass. (81 species). In Flora Orientalis, 74 species belonging to 4 sections, C. sect. Epitrachys DC. ex Duby (38 species), C. sect. Chamaelon DC. (28 species), C. sect. Lamyra Cass. (7 species), and C. sect. Breea Less. (1 species), were given by Boissier (1875).Sommier and Levier (1895) reported 53 species (including the NE of Turkey) without separating them into sections in their work Cirsium del Caucaso.In addition, 111 species belonging to 16 subsections and 7 sections were given by Charadze (1963) in Flora of the USSR, 60 species belonging to 3 sections were given by Werner (1976) in Flora Europaea, and 36 species belonging to 7 subsections and 5 sections were given by Petrak (1979) in Flora Iranica.
