Since the discovery of polyploidy (the presence of more than two chromosome sets in a
nucleus) a century ago, scientists have investigated and speculated about the factors that …

During the past decade, molecular techniques have provided a wealth of data that have
facilitated the resolution of several controversial questions in polyploid evolution. Herein we …

It is timely to re-examine the phenomenon of polyploidy in plants. Indeed, the power of
modern molecular technology to provide new insights, and the impetus of genomics, make …
