Those naughty plants!
Many people, including me, are concerned about potential harm to crop biodiversity from gene flow. Most people’s concern focuses on transgenics. There is a certain probability, albeit small, that transgenes will end up in the progeny of non-transgenic plants, weedy relatives of the crop, or wild relatives that grow nearby due to pollen flow. Transgenes can also be moved from place to place by accidental or purposeful movement of seeds.
How much transgene flow is actually happening is a subject of some controversy, but what about gene flow between non-transgenic plants?
There is potential for problems whenever plants that aren’t supposed to cross stray from their intended mates. Some things to think about include how gene flow happens at the field and genetic levels and what characteristics of the genes themselves can affect permanence of contaminating genes once they get into a variety they shouldn’t be in.
A Vf gene a day keeps the fungus away
Ever gotten apples from the farmer’s market or grocery store only to have them go bad in the back of your fridge? I know I have. Just a few weeks ago, I got about 20 apples from the CSA. Unfortunately, I can only eat so many per day and they started to go bad before I got to eat them. Some of them got really nasty (as you can see to the right) within just a few days despite being in the fridge.
Eating locally is great, but since apples only ripen once per year, and they spoil relatively fast, that means we only have fresh apples for a short time each year. That’s too bad, since apples are a wonderful crunchy snack loved by kids and adults that provide health benefits from their fiber and antioxidants.




Is space beer risky?
Sure, it’s cool, and I wouldn’t mind having a taste, but my first thought after reading Barley + Space = Space Beer! on Wired was: were there any mutations in the barley or hops that were caused by the exposure to gamma rays, etc while in space? Should the lucky few who get to try it be worried about unintended changes in the barley and hops from gamma rays and other mutagens in space?
