DOI: 10.1002/bies.202000105
Abstract: Polyploid cells contain multiple copies of all chromosomes. Polyploidization can be developmentally programmed to sustain tissue barrier function or to increase metabolic potential and cell size. Programmed polyploidy is normally associated with terminal differentiation and… read more here.

DOI: 10.1016/j.ympev.2017.11.007
Abstract: A reliable taxonomic framework and the identification of evolutionary lineages are essential for effective decisions in conservation biodiversity programs. However, phylogenetic reconstruction becomes extremely difficult when polyploidy and hybridization are involved. Veronica subsection Pentasepalae is… read more here.

DOI: 10.1111/jeb.14055
Abstract: It is broadly assumed that polyploidy success reflects an increase in fitness associated with whole‐genome duplication (WGD), due to higher tolerance to stressful conditions. Nevertheless, WGD also arises with several costs in neo‐polyploid lineages, like… read more here.

Reticulate Evolution in the Western Mediterranean Mountain Ranges: The Case of the Leucanthemopsis Polyploid Complex

DOI: 10.3389/fpls.2022.842842
Abstract: Polyploidization is one of the most common speciation mechanisms in plants. This is particularly relevant in high mountain environments and/or in areas heavily affected by climatic oscillations. Although the role of polyploidy and the temporal… read more here.
