Hi, I'm Doug Soltis from
the University of Florida.
And today we're going to talk about
polyploidy, or genome doubling,
in flowering plants and show that
one plus one is better than two.
So let's start with some background.
We'll start with definitions:
what is genome doubling
versus allopolyploids, the
importance of polyploidy,
and then a bit about the
formation of polyploids.
After that background, we want to
overview some recent discoveries
in the field of genome doubling.
We'll reconsider some of
the traditional tenets
of polyploid evolution, looking
at the frequency of polyploidy,
polyploidy and its role
the importance of autoployploidy.
We'll talk about the multiple
origins of polyploids,
and then finally, discuss
polyploids as genomically
dynamic organisms, looking
at genomic expression,
chromosomal changes, and what we
can learn from the study of recently
formed polyploid species.
So let's get started.
Are you ready?
So let's begin with some
definitions as background,
and then from there,
we'll move quickly
into the importance of polyploidy.
