Molecular Phylogeny and Genome Size in European Lilies (Genus Lilium, Liliaceae)

10 p.[EN] Several European lilies populations representing 10 species belonging to section Liriotypus and section Martagon were studied for molecular phylogeny (27 populations) and DNA amount (24 populations). Different Lilium sections were easily differentiated by ITS and rpS4-trnT-trnL sequences and genome size assessments, while an extremely low genetic differentiation was detected at a subsectional level. Most of the variability concentrates on polymorphic sites that have not reached fixation, which considerably complicates the selection of an adequate analysis method. Geographical and ecological variations of genome size and ITS sequences within species were noticeable for several Lilium representatives.Peer reviewe

Contribution to plant genome size knowledge: first assessments in five genera and 30 species of angiosperms from western Balkans

8 p. -- tablasThe first assessments, done by flow cytometry, of nuclear DNA amount for five genera and 30 species of angiosperms (three monocots, 27 eudicots) from the western Balkan Peninsula, including eight taxa with some degree of endemism to this area, are presented here. These data complement the substantial existing information on plant genome size in this region, now accounting for 670 species and subspecies studied for this character.The authors are grateful for the support received from Ministry of Education and Science of Federation of Bosnia and Herzegovina (project 05-14-4565-1/12), Faculty of Forestry (University of Sarajevo), Centre National de la Recherche Scientifique (CNRS,France), the Agència per a la Gestió d’Ajuts Universitaris i de Recerca (AGAUR, Catalan government, projects 2012BE100508 and 2009SGR439) and the Dirección General de Investigación (Spanish government, CGL2010-22234-C02/BOS, subprojects 01 and 02).

Quantitative structure-activity relationship study of xanthene derivatives

Xanthenes are important class of biologically active compounds due to their broad spectrum of pharmacological activities such as bactericidial, anti-inflammatory, antiviral and antiproliferative activity. The aim of this study was to create predictive QSAR (Quantitative Structure-Activity Relationship) model to identify most important chemical features that influence antiproliferative activity of xanthene-3-on and xanthene-1,8-dione derivatives on HeLa cervical carcinoma cell lines. ...18th International Conference on QSAR in Environmental and Health Sciences, June 11-15, 2018, Bled, Sloveni

Controlling the Polymorphism and Topology Transformation in Porphyrinic Zirconium Metal-Organic Frameworks via Mechanochemistry

The mechanochemical approach has been used here for preparation and polymorph resolution in porphyrinic MOF-525/PCN-223 zirconium metal-organic frameworks system, achieving pure target MOF phases in 30-60 minutes milling. In specific reaction condition, MOF-525 forms rapidly by milling but transforms into PCN-223, confirming it to be the kinetic phase in this polymorphic system. ESR measurements showed a strong effect of internal MOF structure on the spin structure of paramagnetic cations coordinated into porphyrin linkers, which show potential for these polymorphic MOFs in spintronics application
