Picky plants: Do they 'choose' the best fungal partner?

MADISON, Wis.---Every time we make a choice, whether between job offers in two different cities or about what to have for dinner, evaluating the costs and benefits of each option is part of the process. Researchers at the University of Michigan are finding that the ability to actively select one option over another may no longer be reserved for higher animals; in fact, plants may make choices too.

Many plants form partnerships with fungi that live in the soil. Attached to the plant's roots, the fungus provides the plant with nutrients needed for growth---usually phosphorous---and the plant provides the fungus with something it needs, usually carbon. Many plants show increased growth when they team up with a fungus, but all fungi are not created equal. Depending on the environment, one fungus may cost the plant more or less carbon in exchange for the nutrients the fungus makes available to the plant.

And according to a paper to be presented at the annual meeting of the Ecological Society of America on Aug. 8 by U-M doctoral student Miroslav Kummel, "plants may be actively 'choosing' the species of fungus that supports the highest growth for the plant."

Depending on environmental factors such as soil type or amount of light, fungi differ in their effects on plant growth, and a plant living in the shade may be better off with a different fungus than a plant living in the sun. "Of course this is the result of long-term selection," says Deborah Goldberg, a professor of ecology and evolutionary biology and one of Kummel's faculty advisers, "but the consequences are the same as if it were a cognitive choice, and that's pretty cool."

Kummel looked at the distribution pattern of different types of fungi growing on balsam fir seedlings in an area with light conditions ranging from full sun to full shade. He found that a fir seedling living in the shade associates with a different fungus than a fir seedling living in the sun, and tha
