Functional Reprogramming of Polyploidization in Megakaryocytes [PDF]

Developmental Cell, 2015
Polyploidization is a natural process that frequently accompanies differentiation; its deregulation is linked to genomic instability and cancer. Despite its relevance, why cells select different polyploidization mechanisms is unknown. Here we report a systematic genetic analysis of endomitosis, a process in which megakaryocytes become polyploid by ...

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

Polyploidization in Liver Tissue

The American Journal of Pathology, 2014
Polyploidy (alias whole genome amplification) refers to organisms containing more than two basic sets of chromosomes. Polyploidy was first observed in plants more than a century ago, and it is known that such processes occur in many eukaryotes under a variety of circumstances.

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species

, 2011
Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

Maternal origin, genome constitution and evolutionary relationships of polyploid Elymus species and Hordelymus europaeus

, 2011
The trnS/psbC region of chloroplast DNA (cpDNA) was sequenced for 18 Elymus polyploid species, Hordelymus europaeus and their putative diploid ancestors. The objective was to determine the maternal origin and evolutionary relationships of these polyploid
