It turns out that one particular gene from celery — the one that controls the enzyme mannitol dehydrogenase — greatly improves the life and quality of rose petals when that gene is spliced into the rose genome. So in an effort to help you get more value from your Valentine's Day gifts, North Carolina State horticultural scientists Dr. John Dole and Dr. John Williamson are leading an effort to insert that gene into roses to create a new superflower less prone to wilt and more resistant to disease, according to PhysOrg.com.
"This gene is naturally found in many plants, but it's uncertain whether the rose already has it," said Williamson. "If it does, it doesn't produce enough enzyme to help the plant fight against petal blight."
Petal blight, or botrytis, is a common post-harvest disease in roses that produces wilty, mushy petals. It's caused by invading fungal pathogens that break down the flower's defenses by producing a sugar alcohol called mannitol. Plants that produce enough mannitol dehydrogenase enzyme, like celery, can better break down this sugar alcohol and thus maintain their form for longer.
Roses that contain the celery gene don't smell any different than normal roses, according to the N.C. State researchers. The only noticeable difference between normal roses and these superflowers should be their vase life.
The research is part of a larger effort by Dole and Williamson to build a better rose. Besides implanting the celery gene, the researchers are also examining the types of sugars best suited for mixture with water to keep the plants thriving after they've been harvested. They are even studying how variance in water quality across the country affects the life expectancy of cut roses.
The ultimate goal, according to Dole, is to get roses to survive for up to three to four weeks after they've been harvested. If they succeed, before long your loved one may be able to cherish her Valentine's Day gift well into spring.

Did anyone else notice that mannitol dehydrogenase is not a gene. It's an enzyme.

It is quite entertaining that most people consider this to be some unusual borderline science fiction thing. As a molecular biologist, I have personally inserted genes and/or deleted or modified genes in E. coli, yeast, human cells in a culture, and nematodes on multiple occasions, and I don't even specialize in transgenics. We just use them as models for other aspects of research. Knocking out/in/down genes, and transgenics are so absurdly common. Some labs have upwards of 10000 different.... More

Saying this will, in anyway, lead to some kind of doomsday scenario is like saying my iPod will start the robot uprising...

domestic dogs and cats and cattle are just a few examples of things that were NOT created by mother nature

Some peoples opinion even reflects that selective breeding isn't natural,these people ought to try an education-one species often have an effect on the physical and social characteristics of another- through a shared course of evolutionary development -coexistence and even teamwork ; that in itself isn't unnatural-

As are the genetically modified crops scientists have created that can grow in arid, drought battered climates (read: Africa). Opposition to genetic modifications are a luxury of the privileged and complacent. Anyone who fears this stuff needs to grow up and realize how important GMOs are.

Does anyone want their flowers to last a month in a vase? Wouldn't you get sick of them?

Can you dip them flowers in peanut butter ? 'Cause if you can eat 'em, too, I'm sold !
