complement is known as the C-value and is a key biodiversity character of fundamental …

Monocot genomic diversity includes striking variation at many levels. This paper compares
various genomic characters (eg, range of chromosome numbers and ploidy levels …

Abstract Crucifers (Brassicaceae, Cruciferae) are a large family comprising some 338

Aims Habitats on ultramafic substrate present a hostile environment for plant development.
We aimed to determine whether any particular range of genome size is favoured in such …

Flow cytometry has become the method of choice to measure the DNA content (genome
size) in plants. Ease of sample preparation, fast acquisition, and accurate measurements …

Polyploidy is a key factor in the evolution of higher plants and plays an important role in the
variation of plant genomes, leading to speciation in some cases. During polyploidisation …

Genome size (GS) diversity is of fundamental biological importance. The occurrence of giant
genomes in angiosperms is restricted to just a few lineages in the analyzed genome size of …

Abstract Background and Aims Hieracium subgenus Hieracium is one of the taxonomically
most intricate groups of vascular plants, due to polyploidy and a diversity of breeeding …

Echinops ritro L.(Asteraceae) is traditionally used in the treatment of bacterial/fungal
infections and respiratory and heart ailments. The aim of this study was to evaluate the …

EPPS, a new heteropolysaccharide from Echinops pungens roots, was extracted by warm
