“Villagers were also made to burn grain bins if they had planted ‘unlucky’ foreign seeds.”
Fighting osteoporosis with lettuce
Researchers have apparently engineered lettuce to express higher levels of the sCAX1 gene which pumps calcium into the cell’s vacuole, leading to 25-32% higher levels of the nutrient in the leaves. Sadly, there’s nothing in the article about genetic variation in Ca content among different varieties, so it’s not clear whether these increases could have been achieved by conventional breeding. Anyway, despite the paper, which I nibbled yesterday, showing the possibility of a link between Ca content and bitterness, there was apparently no difference in bitterness between the normal and biofortified lettuces. So that’s allright then.
Bananas on the radio
Voice of America has five (count them!) articles and podcasts on the banana in Africa. Going to take me a while to get through the whole lot, but I’ll try to post a summary when I do.
Sweet potato diversity identified
Amazingly, there are people out there who can name a sweet potato variety at twenty paces. And in a photograph. Check out the comments to a recent flickr upload of mine showing a market in Rabaul. Now, if only I had geo-referenced it…
Michael plays Virgil
Bioversity’s Michael Mackay was recently interviewed on Radio Australia about plans to lead us all out of genebank database hell. Good luck to him!
