Although many plants are extant polyploids, the number of ancient
polyploidy events that survived on the long term is limited.
Many whole genome duplications seem to be clustered in time around the
Both adaptive and neutral processes might have contributed to promote
the establishment of polyploids.
Fifteen years into sequencing entire plant genomes, more than 30
paleopolyploidy events could be mapped on the tree of flowering plants
(and many more when also transcriptome data sets are considered).
While some genome duplications are very old and have occurred early in
the evolution of dicots and monocots, or even before, others are more
recent and seem to have occurred independently in many different plant
lineages. Strikingly, a majority of these duplications date somewhere
between 55 and 75 million years ago (mya), and thus likely correlate
with the K/Pg boundary. If true, this would suggest that plants that
had their genome duplicated at that time, had an increased chance to
survive the most recent mass extinction event, at 66 mya, which wiped
out a majority of plant and animal life, including all non-avian
dinosaurs. Here, we review several processes, both neutral and
adaptive, that might explain the establishment of polyploid plants,
following the K/Pg mass extinction.
