What is Citrus? Can it be Saved With Breeding?

-

“Citrus” is a term applied to a variety of popular and nutritious fruits, including oranges, grapefruit, lemons and limes.  Citrus breeders are tasked with improving the varieties, which takes decades.  Still, great progress has been made in fruit improvement. 

 However, over the last twenty years a disease called Huanglongbing, or “HLB” (also known as “citrus greening”) has emerged in the USA and threatens the citrus industry.  Today the focus is how to grow improved citrus varieties that can survive this insidious disease.  Dr. Fred Gmitter is a seasoned citrus breeder that has  produced improved fruit varieties, but also is working to identify new varieties to combat HLB.

Food Babe Visits My University

It was 6:30 pm in the lab and I was just thinking about the last things I'd need to get done before I could go home.  Typical night.  Usually I'm riding home about 7 pm, but an email popped up asking me if I was going to go watch the Food Babe.  A click on a link would take me to the note on a UF Dean for Students Good Food Revolution Events website.  Vani Hari would be spreading her corrupt message of bogus science and abject food terrorism here at the University of Florida. Oh joy. There's something that dies inside when you are a faculty member that works hard to teach about food, farming and science, and your own university brings in a crackpot to unravel all of the information you have brought to students. She might have started from honest roots.  Her story says she was duped by an organic yogurt stand (join the club) into buying taro toppings that were filled with artificial, non-organic colors.  She realized that she could use social media to coalesce

Film Review: The Need to Grow

The recurring ads on Facebook pulled at me to watch The Need to Grow , a documentary film about food and farming.  As someone connected with these areas professionally and personally, I thought it would be worth a watch.  Here is a review. First the good things.  The film is nicely shot and well written.  The majority of the work builds on themes such as nutritious diets healthy soils, and efficient energy. Those are the central underlying values of the film, and ones that I wholly endorse.  However, where the film falls apart is in its approaches to achieve those end points.  Two of the "experts" recruited for the film are none other than Jeffrey Smith and Vandana Shiva, two people with little training in science or farming (and no, Vandana Shiva is not a physicist as the film claims).  The narrator is actress Rosario Dawson, who early in the film makes the proclamation, "Agriculture is the most destructive human activity on the planet." It is clear where t

Coordinated Disinformation Campaigns on Twitter

 Today on twitter I kept seeing the same message coming up, over and over again.  What the heck is going on?  Mia's mom wants major restaurant chains to know that she's not exactly up on the science. The link goes to the Center for Food Safety, an organization that really isn't that is much more of an anti-technology club than a food safety concern.  They speak out against any application of biotechnology, such as the release of the disease-suppressing GE mosquitoes in the Florida Keys.  Somehow when CFS launches a twitter campaign they plaster the Tweet Stream with the exact same message over and over again.  My feeling is that they do this to create the impression of a mass consensus, a movement to essentially bully retailers and restaurants. In this case it is the AquaAdvantage Salmon, a fish grown in inland tanks in Indiana.  First invented in 1989, the salmon has had a rocky road to market, despite the magic of growing to market size in half the time and on a fraction
