'Rules' may govern genome evolution in young plant speciesGainesville FL (SPX) Jan 26, 2012 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 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 used to create higher and ... read more |
