A new University of Florida study shows a hybrid plant species may experience rapid genome evolution in predictable patterns, meaning evolution repeats itself in populations of independent origin. Researchers analyzed genes of a naturally occurring hybrid species, Tragopogon miscellus, and the study, published online today in Current Biology, suggests genome evolution in hybrid plants may follow a set of “rules” that determine which parental genes are lost. The research may be...

A new University of Florida study shows genomes of a recently formed plant species to be highly unstable, a phenomenon that may have far-reaching evolutionary consequences. Published online this week in the Proceedings of the National Academy of Sciences, the study is the first to document chromosomal variation in natural populations of a recently formed plant species following whole genome doubling, or polyploidy. Because many agricultural crops are young polyploids, the data may be used...
