GAINESVILLE, Fla. — Researchers from the University of Florida and six other institutions have unlocked some of the key foundations for the evolution of seed and flowering plants.

The study, to be published online Sunday in Nature, is the first to identify the occurrence of ancient genome duplication events and show the genomes of seed and flowering plants duplicated before each group of plants diversified. It introduces new factors for further molecular research on the organisms humans depend on for food, clothing and shelter. (more…)

*Research genetically traces flowers to a single common ancestor*

From southern Africa’s pineapple lily to Western Australia’s swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life.

New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming similar to a water lily may have started it all.
