Evolutionary chromosome change involves significant variation in DNA amount in diploids
and genome downsizing in polyploids. Genome size and karyotype parameters of …

DNA content was estimated by flow cytometry in seventeen taxa from the Dilatata,
Quadrifaria and Paniculata groups of Paspalum and five synthetic hybrids. Results were …

Karyotype characterizing the phenotypic aspects of the chromosome complement
represents structural and functional organization of the nuclear genome. Its constancy …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Polyploidy, the condition of possessing more than 2 complete chromosome sets in the same
nucleus, is frequent in nature and has implications for a species' prospects for evolution …

Genome size variation accompanies the diversification and evolution of many plant species.
Relationships between DNA amount and phenotypic and cytological characteristics form the …

Recent molecular studies in the genera Aegilops and Triticum showed that
allopolyploidization (interspecific or intergeneric hybridization followed by chromosome …

Two main attempts have been suggested for the biological significance of endopolyploidy:(i)
provision of high DNA amounts to support high synthetic demands in certain cells and (ii) …

The variation in genome size and basic chromosome number was analyzed in the wide
range of angiosperm plants. A divergence of monocots vs. dicots (eudicots) genome size …

Background Genome doubling may have multi-level effects on the morphology, viability and
physiology of polyploids compared to diploids. We studied the changes associated with …
