Reports from the Botany & Mycology 2009 meeting
Researchers convened July 25-29 at the Botany & Mycology 2009 meeting in Snowbird, Utah. Presented work included updates on some not-so-welcome plant visitors and a bat-plaguing fungus menace.
Tree of heaven outsources some of its nutrient-gathering efforts
SNOWBIRD, Utah — A notorious invader called the tree of heaven may have an unusual way of outsourcing some of its nutrient-finding efforts.
Ailanthus altissima trees, like most plants, can’t process nitrogen from the air into a usable form, but with help, clovers and many other legumes can. Bacteria housed in root nodules snag some of the abundant nitrogen in the air and convert it to a form that plants and other living things can use.
Research now shows that trees of heaven exude a substance that revs up the roots of clover plants to
