We present the first phylogenomic analysis of relationships among all ten families of Liliales, based on 75 plastid genes from 35 species in 29 genera, and 97 additional plastomes stratified across angiosperm lineages. We used a supermatrix approach to extend our analysis to 58 of 64 genera of Liliales, and calibrated the resulting phylogeny against 17 fossil dates to produce a new timeline for...
The effect of various agents that cause metaphase arrest in dividing cells was studied on the rapid reversible darkening of frog skin under the influence of melanocyte-stimulating hormone (MSH). Darkening is due to dispersion of melanin granules in melanocytes and is thought to be accompanied by a gel-to-sol cytoplasmic transformation. After subsequent washing the skin lightens, with aggregatio...
This study is aimed at determining the characteristics and microbiota of soil upon which some Turkish Colchicum (Colchicaceae) species naturally grows. For this aim rhizosphere samples balansae Planch., triphyllum Kunze variegatum L. were analysed in research. The carbon mineralization rate C. p<0.05 significantly different from that other two soils. In terms nitrogen mineralization, sig...

With the objective of clarifying some aspects of the biogeography, phylogeny, and taxonomy of the genus Androcymbium, we sequenced three chloroplastic DNA noncoding regions (trnL intron, trnLtrnF IGS, and trnY-trnD IGS). These data were analyzed with maximum parsimony and the ancestral areas methods following Bremer. Results show that Androcymbium is not monophyletic and that the origin of its ...
