Cell polyploidisation can be achieved by endoreduplication, which consists of one or
several rounds of DNA synthesis in the absence of mitosis. As a consequence …

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) …

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 played an important role in the evolution of the three most important crops: wheat,
maize and rice, each of them providing a unique model for studying allopolyploidy …

Endoreplication—a process that is common in plants and also accompanies changes in the
development of animal organisms—has been seen from a new perspective in recent years …

Polysomaty was found in all organs of tomato (Lycopersicon esculentum cv. Moneymaker)
tested. The first endoreplications occurred in cotyledon and hypocotyl during germination …

Polysomaty analysis of the succulent portulaca (Portulaca grandiflora Hook.) plant was
carried out using flow cytometry. For both diploid and tetraploid plants, mature leaf tissue …

Whole-genome duplication (polyploidy) occurs frequently and repeatedly within species of
plants. According to the source of the genomes giving origin to a polyploid plant species …

Colchicine was applied in liquid B5 medium supplemented with 0.49 μm N 6 (δ 2-
isopentenyl) adenine to tissue culture derived cocoyam plantlets. Tetraploids (4n= 52) and …

During tomato fruit development the DNA synthesis of the pericarp was measured. After
staining of the isolated nuclei with DAPI the relative DNA amount was analyzed using a flow …
