“…The shortest total haploid chromosome length (20 μm) was observed in the Tehran population of T. parthenium. The karyotype length is positively correlated with genome size (Garnatje et al 2004;Garcia et al 2005), so it could be concluded that T. polycephalum subsp. duderanum and T. parthenium (Tehran population) would possess highest and lowest genome size among the studied taxa, respectively.…”

Chromosome number and morphology in nine taxa belonging to 10 populations of Tanacetum L. (Asteraceae) were investigated using karyological techniques. The chromosome number found in eight species was 2n = 18 (T. balsamita, T. budjnurdense, T. sonbolii, T. archibaldii, T. persicum, T. parthenium and T. canescens) while T. polycephalum subsp. duderanum and T. polycephalum subsp. azerbaidjanicum had 2n = 36. Six records are new while four records confirmed the previous data. At mitotic metaphase, all chromosomes had median point (M), median region (m), submedian (sm) or subterminal (st) centromeres. The karyotypes are classified in types 2A or 2B, showing the presence of a primitive symmetrical karyotype in the genus Tanacetum. An updated checklist of karyological data of the genus is also presented.

“…Two samples of each individual were extracted and measured independently. Fluorescence analysis was carried out using an Epics XL flow cytometer (Coulter Corporation, Hialeah, FL, USA) at the Centres Científics i Tecnològics de la Universitat de Barcelona, with the instrument set up with the standard configuration as described in Garnatje et al (2004). The total nuclear DNA content was calculated by multiplying the known DNA content of the standard by the quotient between the 2C peak positions of the target populations and the standard in the histogram of fluorescence intensities.…”

This study contributes the first genome size data for wild populations of Cynara cardunculus, the presumed progenitor of artichoke and cultivated cardoon. C-values estimated by flow cytometry are 2C = 1.98-2.14(3.03) pg for wild cardoon (10 populations), 2C = 2.10-2.11 pg for cultivated cardoon (two accessions) and 2C = 2.05 pg for artichoke (one accession). Chromosome counting (carried out for all material except the artichoke) establishes diploidy in all accessions. In order to provide a phylogenetic framework for Tunisian populations, internal transcribed spacer (ITS) region was sequenced and analysed together with previously published Cynara sequences. The wild and crop cardoons present similar karyological features and genome sizes despite strong morphological differentiation, with the single exception of a Tunisian population (from Tajerouine), which exhibits a 42-53% higher genome size. Along with Sicilian individuals, Tunisian wild C. cardunculus appear genetically closer to artichoke and cardoon than to studied wild relatives from the remaining distribution. This highlights the crucial importance of taking into consideration the North African territory in deciphering the history of C. cardunculus crop domestication.

“…Two independent replicates of each individual and five individuals per population (three in a very few cases) were analysed. All the analyses for a given population were performed on the same day (see more methodological details in Garnatje et al (2004). Lycopersicon esculentum Mill.…”
