Creating Fragrant Flowers

When was the last time you got a bouquet of flowers that had a
fragrant smell? While there’s no shortage of beautiful looking flowers

sale, many have little if any scent anymore. As the Great Lakes Radio

When was the last time you got a bouquet of flowers that had a fragrant smell? While there’s no shortage of beautiful looking flowers for sale, many have little, if any, scent anymore. Ast he Great Lakes Radio Consortium’s Tamar Charney reports, it’s a problem one scientist has gotten a whiff of:


Flowers have lost their smell as flower growers have bred them to be big and brightly colored. Eran Pichersky is a biologist at the University of Michigan. He studies the smell of flowers. Pichersky is focusing his genetics research on whether it’s possible to bioengineer a flower’s scent.


“We actually have some collaboration with biotech companies who are trying to use some of the genes and enzymes we’ve isolated to put them back into plants so that the plant makes more scent, or even new scent that they didn’t make before.”


But it’s not florists who are interested in this work, it’s farmers. Pichersky’s research means it might be possible to alter the smell of flowers in ways that entice bees to visit crops more often, or even attract other insects to do the pollination work. That increase in pollination could mean an increase in crop yields.

Beetle Controls Purple Loosestife

A European plant called purple loosestrife is increasingly making
itself at home near lakes, wetlands, and meadows throughout the Great
Lakes region. That’s bad news for native plants that are pushed out by
the aggressive newcomer. But help could be on the way. The Great
Lakes Radio Consortium’s Tracy Samilton reports on a program to
introduce a loosestrife-munching beetle:

New Research in Drug Development

Scientists say they might have found a more efficient way to produce drugs
and chemicals from plants. The Great Lakes Radio Consortium’s Lester Graham
reports… it might reduce the cost of developing drugs:

Toxin Eating Geraniums

Canadian scientists are applying for a patent on using geraniums to clean up
toxins. The Great Lakes Radio Consortium’s Lester Graham reports it’s
controversial because the patent would control the use of a naturally
occurring flower:

Peter Raven-Are We Facing a Mass Extinction?

  • Peter Raven is the director of the Missouri Botanical Garden. More than that, Raven is a world-leader in the effort to classify, understand, and use plants in a sustainable fashion.

Recently Time Magazine labeled Peter Raven one of the "Heroes of the Planet"
for his work in understanding plants and the environment. Raven is the
director of the Missouri Botanical Garden. In the first installment of a
three-part interview at the botanical garden, the Great Lakes Radio
Consortium’s Lester Graham talked with Peter Raven about his conclusion that
we’re facing a mass extinction of species:

A Revolution Among Plant Scientists

Scientists are discovering new genetic information about plants is
upsetting the natural order of things. The Great Lakes Radio
Consortium’s Lester Graham reports that they’re also finding a whole new
world of possibilities for using plants for medicines and products:

Not So Poisonous Poinsettias

The poinsettia is a popular symbol of the holiday
season. But the colorful plants have been stigmatized as highly toxic.
And for years, people have been warned to keep them away from children
and pets. But this season, you may be able to rest easy, unafraid of
your poinsettia plants. The Great Lakes Radio Consortium’s Wendy Nelson
explains:

Trees Used to Clean Up Toxins

Researchers are finding ways to use plants to clean up contaminated
sites. The Great Lakes Radio Consortium’s Lester Graham reports on a
project to use genetically altered trees to pull certain kinds of
pollution from the ground:

Genetically Altered Trees Eat Mercury

In an article in the journal "Nature Biotechnology" researchers saythey’re developing plants that clean up mercury contamination. TheGreat Lakes Radio Consortium’s Lester Graham reports:
