Barcoding the Kruger Park

Botanists are collecting all the plants in the Kruger Park, according to this article. Fine, admirable: it’s good to have a full inventory of the flora of such an important protected area. We’ll know what crop wild relatives and medicinal plants grow there, for example, and thus perhaps be in a better position to tailor management interventions to suit them (at least in some parts of the park), and monitor changes. But actually that’s not why the specimens are being collected. Rather:

“We hope to be the team to identify the genetic bar-code for plants,” said team leader Dr Michelle van der Bank of the department of Botany and (Plant) Biotechnology.

That’s at the University of Johannesburg. I’m not sure I understand the logic, though. I doubt the Kruger is the most botanically diverse place in South Africa, or the most convenient (not to say safe) to collect in. What am I missing here? Anyway, it should make for some fun fieldwork.

Gumming up the works

Researchers in Canada have developed an alternative to gum arabic by treating “soybean soluble polysaccharide” with some fancy enzyme. Bad news for gum arabic (an exudate of Acacia senegal) collectors and exporters in Sudan and Nigeria. Good news for soybean farmers around the world, I guess. But who’s in greater need of good news?

Setting the bar

And here’s another fun blog which the one mentioned in the previous post alerted me to. “The Barcode Blog” is “about short DNA sequences for species identification and discovery.” It’s been going for a couple of years but a quick search revealed only one agriculture-related posting, which had to do with the use of barcoding to identify pests and invasives. But I suspect that will change.
