Tricking plants to see the light may control the most important twitch on Earth
Date:8/4/2014

MADISON, Wis. Copious corn growing in tiny backyard plots? Roses blooming in December? Thanks to technology that the University of Wisconsin-Madison's Richard Vierstra has been developing for years, these things may soon be possible. And now, new findings out of the genetics professor's lab promise to advance that technology even further.

For the first time, Vierstra and his team have revealed the structure of the plant phytochrome, a critical molecule that detects the light that tells plants when to germinate, grow, make food, flower and even age. Like eyes, the phytochrome is a light sensor that converts sunlight into chemical signals to get these jobs done. By manipulating it, the group can alter the conditions under which all plants grow and develop.

Vierstra's group published the structure in a recent issue of the journal Proceedings of the National Academy of Science. His team also presented its results this month at the annual meeting of the American Society of Plant Biologists in Portland, Oregon.

"It's the molecule that tells plants when to flower," says Vierstra. "Plants use the molecule to sense where they are in the canopy; they use the phytochromes for color vision to sense whether they are above, next to or under other plants."

Vierstra previously determined the structure of a similar phytochrome from light-sensing bacteria, which guided his work in plants. He already has several patents on the technologies derived from these structures and has been in talks to commercialize them. The determination of a plant phytochrome three-dimensional structure will only accelerate improvements to the technology.

One of the biggest moves in agriculture, Vierstra says, is to be able to grow plants at higher density, allowing producers to plant more crops in a given area, thus saving space and other resources.

Currently, there is a limit to how closely plants can grow relative to their nearest neighb
