Relationships And Generic Delimitation Of Eurasian Genera Of The Subtribe Asterinae (Astereae, Asteraceae) Using Molecular Phylogeny Of Its, Elena Korolyuk, Alexey Makunin, Tatiana Matveeva

The subtribe Asterinae (Astereae, Asteraceae) includes highly variable, often polyploid species. Recent findings based on molecular methods led to revision of its volume. However, most of these studies lacked species from Eurasia, where a lot of previous taxonomic treatments of the subtribe exist. In this study we used molecular phylogenetics methods with internal transcribed spacer (ITS) as a marker to resolve evolutionary relations between representatives of the subtribe Asterinae from Siberia, Kazakhstan, and the European part of Russia. Our reconstruction revealed that a clade including all Asterinae species is paraphyletic. Inside this clade, there are species with unresolved basal positions, …

In the present study, chromosome morphology of 32 Scorzonera L. Taxa, including 19 species endemic to Turkey, was analyzed. The plant materials were collected from different natural populations of Turkey between 2005 and 2011. The classification of chromosomes, the length of the long and short arm, haploid chromosome length, arm ratio, and relative chromosomal length were measured by software image analyses. The basic chromosome numbers were determined as x = 6 and x = 7. Two types of ploidy levels were observed as diploidy and tetraploidy. Karyotype asymmetry indices, TF%, As K%, Syi, Rec, A, A1, and A2 were also …
