Genes may travel from plant to plant to fuel evolution
Date:2/16/2012

PROVIDENCE, R.I. [Brown University] The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way. But evolutionary biologists from Brown University and the University of Sheffield have documented another avenue, through the passing of genes from plant to plant between species with only a distant ancestral kinship.

How this happened is unclear. But the researchers show that not only did a grouping of grasses pass genes multiple times over millions of years, but that some of the genes that were transferred became integral cogs to the plants' photosynthetic machinery, a critical distinguishing feature in C4 plants, which dominate in hot, tropical climes and now make up 20 percent of the Earth's vegetational covering.

"As far as we know, this is the first case where nuclear genes that have been transmitted between plants have been incorporated into the primary metabolism and contributed to the evolution of a new trait, in this case C4 photosynthesis," said Pascal-Antoine Christin, a postdoctoral researcher in the Department of Ecology and Evolutionary Biology at Brown.

In a paper published in Current Biology, the researchers from Brown, Sheffield, and other universities in the United States, United Kingdom, and France investigated the ancestry of two genes encoding enzymes important in C4 photosynthesis phosphoenolpyruvate carboxylase (ppc) and phosphoenolpyruvate carboxykinase (pck) and these enzymes' historical presence and function in a common and well-studied grass, Alloteropsis. The biologists initially studied the genes in closely related species, three C4 plants (Alloteropsis angusta, Alloteropsis cimicina, and Alloteropsis semialata) and one C3 plant (Alloteropsis eckloniana). The goal was to learn the evolutionary history of the ppc and pck genes, which were present in their C3 common ancestor and wer
