“…Root tip meristerms obtained directly from natural populations were used for chromosome analysis. The tips of roots were cleaned of soil particles, cut off and pretreated with 0.05% colchicine for 2–5 h (Inceer, Hayirlioglu‐Ayaz & Beyazoglu, 2002). They were then fixed in ethanol‐acetic acid (3:1) for at least 24 h at 4 °C, hydrolysed in 1 n HCl at 60 °C for 10 min and then rinsed in tap water for a minimum of 2–3 min.…”

Twenty‐two chromosome counts of 19 taxa in the tribe Anthemideae of the family Asteraceae are reported from north‐east Anatolia, Turkey. The taxa belong to the subtribes Achilleinae (four Achillea taxa), Anthemidinae (five Anthemis taxa), Artemisiinae (two Artemisia species), Leucantheminae (one Lecanthemum species), Matricariinae (two Tripleurospermum species) and Tanacetinae (five Tanacetum taxa). Six counts are new reports, seven are not consistent with previous counts, and the remainder are confirmations of very limited previous data. Most of the populations of Anthemideae studied have the basic number x = 9, with ploidy levels ranging from 2x to 7 to 8x, but dysploidy is also present, with one diploid species, Artemisia austriaca, having x = 8. © 2007 The Linnean Society of London, Botanical Journal of the Linnean Society, 2007, 153, 203–211.

Chromosome number and morphology in 14 taxa belonging to 19 populations of Tripleurospermum Sch. Bip. were studied using karyological and numerical taxonomical techniques. Data on chromosome measurements were analysed using cluster analysis. Chromosome numbers of these taxa are 2 n = 2 x = 18, 4 x = 36 and 5 x = 42-48. Seven records are new, two are not consistent with previous counts, and the remainder confirm the very limited previous data (one to three records). A new ploidy level (pentaploidy) is reported for the first time for the genus. Some correlations between ploidy levels and morphological characters are noted and several systematic and evolutionary aspects of the genus are discussed in the light of karyological data.

“…The study of the genome is a significant approach to comprehend the evolutionary mechanisms of plant species [ 25 ]. Yet, the knowledge of Fabeae diversity has mainly focused on chromosomal analyses and/or morphological characters [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. Moreover, most reports on Fabeae C-value have been provided by Feulgen microdensitometry.…”

DNA content is an important trait linked to the evolutionary routes of taxa and often connected to speciation. In the present study, we studied C-values variation across the Cypriot Fabeae gene pool. Several hundred plants (Vicia spp., Lens spp., Pisum spp.) were sampled across Cyprus. Accurate estimates were established by flow cytometry and propidium iodine staining for 155 discrete populations/accessions. A ten-fold variation was detected across lineages with 1C DNA content varying from 1.584 pg for V. cretica (ARI02420) to 13.983 pg for V. faba (ARI00187). In general, flow cytometry was precise for the characterization of species, even though there were instances of genome overlapping across taxa. Most analyses in the current work refer to species that have not been characterized before by flow cytometry (or any other DNA content estimation method). Still, a correlation to C-values previously reported in Kew Plant DNA C-values database was attempted. A high degree of correlation except for V. dalmatica was established. The evaluation of genome size trait in relation with the Fabeae phylogeny, revealed that Pisum and Lens genera were rather homogenous, but an astonishing fluctuation was shown for Vicia spp. Moreover, it was established that genome up- or down-scaling was not directly linked to speciation drivers. The genomic size measurements presented here could deliver extra quality control for the identification and characterization of taxa in germplasm collections, particularly in cases where species share morphological characters.
