James and the Giant Corn Genetics: Studying the Source Code of Nature

Sunday Links 12/6

MAT Kinase tells the story of some of a cool, weird, (and potentially deadly) fruit created using nothing but conventional breeding techniques in Plumalmodterine.

Steve Savage has the conversation with a Greenpeace campaigner I’ve always wanted to have with the people who can constantly be found soliciting money for similar organizations on my walk to work.

Steve’s post reminded me of this awesome (and freely available article) from Plant Physiology: Forbidden Fruit: Transgenic Papaya in Thailand* which is highly recommended reading for anyone interested in genetic engineering, the developing world, and the role of NGOs like Greenpeace.

I’m considering making this a regular feature. I often read cool articles, but it feels weird to put up a post that just says “go read this” when I don’t have anything of my own to add. Anyway, the test of whether this will be a feature or a fluke will be if I remember to post another one in a week.

*I know I’d previously mentioned this in my post on virus-resistant papayas, but I think there are at least several new readers since then and I’ve been dismayed to find out how little publicity this article seems to have received when it first came out.

See the Tomorrow’s Table Seminar

Mary points out that, after a free registration, you can see a streaming video of Pamela and Raoul’s talking about the same issues at the Long Now Foundation.

Quick Question On Student Debt

Filed under: Fun With Numbers — Tags: — James @ 12:49 pm

Numbers in this post come from from The Project on Student Debt. I can’t vouch for their accuracy myself, but assuming they are:

Which of these numbers do you think is more informative?

  1. Among college students in Iowa graduating with debt, the average amount owed was $28,174 (73% of students graduated with debt)
  2. Among all college students who graduated in Iowa last year, the average student owed $20,567? (more…)

Make Sure Your Voice is Heard

Filed under: agriculture,Campus Life,Feeding the world,Politics — James @ 9:51 pm

Another positive side effect of extending my stay in Iowa for another week (besides having the chance to work from a room with a view), was getting the chance to see the Pamela Ronald and Raoul Adamchak give a presentation on the same themes are their book “Tomorrow’s Table” here on campus (I’ve reviewed the book itself).

Pamela Ronald is actually going to be talking in Berkeley late next month, but, in addition to a sneak peak of the presentation (which was really good) listening the the question session following their talk was a great chance to resample the perspective of the other major group involved in the debate on genetic engineering (besides anti-gmo activists, corporate public relations people, and plant scientists like me), farmers and agronomists.

What Pamela and Raoul advocate, distilled down to a single phrase, is agriculture utilizing “the best technology and the best practices.” The best technology is pretty clearly going to incorporate at least some genetically engineered traits, but the best farming practices will definitely incorporate approaches from organic agriculture.

Edible Cottonseed

Over 102 million bales of cotton (more than 24 million tons of cotton) were grown around the world last year. I wouldn’t surprise me to hear cotton called the single most important (and widely cultivated) food crop on the face of the planet. But does it have to be a non-food crop?

Clearly no one (nor any livestock) wants to eat the cotton fibers themselves, but they aren’t the only product of the plant. After to cotton plant flowers, the cotton fibers grow around the developing seeds. The combined mixture is harvested each year, after which the seeds are removed from the cotton fibers before the cotton is baled and sold.*

The seeds of the cotton plant are full of protein and oils and since cotton is already grown as a source of fiber (and the seeds are even harvested and sorted out of the cotton fibers already) adding them to the food supply** doesn’t require any further land to be cultivated or increased input costs. Obviously there is a catch… (more…)

China’s Approval of Bt Rice Confirmed

Filed under: agriculture,Feeding the world — Tags: , , , — James @ 7:22 pm

Read today’s story from Bloomberg. I’d discussed my own thoughts when it was a story based on anonymous sources last week.

From the article:

China produces 31 percent of the world’s rice and 20 percent of its corn, U.S. Department of Agriculture data show. …[China] uses 7 percent of the world’s arable land to feed a quarter of its population.

China has only 7% of the world’s farmland yet feeds more than 1.3 billion people (and still growing). No wonder they’re investing so heavily in crop/plant science.

Another one I recently read (if it was you, sorry for not attributing it properly, the comparison just stuck in my head) was that India and Argentina are about the same size (India is about a quarter bigger) yet India must feed 30 times as many people!*

*Of course this isn’t quite a fair comparison since Argentina exports so much food to Western Europe, since those countries can afford to buy food abroad instead of focusing on increasing local production, and China and India must

One of the Joys of Comparative Genomics

Filed under: Computers and Coding,research stories — Tags: , — James @ 1:26 pm

I was originally scheduled to fly home yesterday, but was forced to extend my stay by unfortunate chain of events that (among other things) has resulted with me swearing off contact lenses for the foreseeable future.

If I worked with arabidopsis or brachypodium, I’d probably have plants flowering this week that I’d be missing. Without the chance to make the crosses I needed to continue my research I might be set back a month or more while I waiting for new plants to grow. If I was mostly doing wet lab work, I wouldn’t fall as far behind assuming I’d gotten all my projects properly refrigerated or frozen before leaving for Thanksgiving, but the whole week I was gone would still be a complete loss.

Fortunately, I now study comparative genomics, which means, while I won’t get as much done this week as I normally would have, I’m definitely going to continue working. I’ve already shown off my workstation in the lab.

And here is where I’ll be working most of this week.

I’ve been advised, by people who’ve been doing a lot longer than I have, that working on a laptop long-term is a great way to burn out your hands (carpel tunnel), but for a week it’s no big deal. I can get more work done from here, thousands of miles away, than from an apartment a few blocked from the job, because the faster internet connection means I’m better able to access my own workstation (the first computer pictured), two of the my lab’s servers, and even a Linux box I left running in my apartment, all of which was using for different parts on my work on Monday.

If you look closely you’ll also notice one other difference between the permanent and temporary digs. Just for this week, I have a window!
