Los estudios citotaxonómicos de especies vegetales suponen una herramienta muy útil para analizar procesos evolutivos. Desde inicios del siglo XX el número, tamaño, morfología, el comportamiento de los cromosomas durante los procesos de mitosis y meiosis e incluso el tamaño del genoma han proporcionado abundante información en este sentido....

Background and Aims Chromosome evolution leads to hybrid dysfunction and recombination patterns and has thus been proposed as a major driver of diversification in all branches of the tree of life, including flowering plants. In this study we used the genus Linum (flax species) to evaluate the effects of chromosomal evolution on diversification...

• Background and Aims Polyploidy is considered one of the main mechanisms of plant evolution and speciation. In the Mediterranean Basin, polyploidy has contributed to making this region a biodiversity hotspot, along with its geological and climatic history and other ecological and biogeographical factors. The Mediterranean genus Centaurium...
