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 or polyploidy, define autopolyploids 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 in diversification, 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.
