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.
Traditional African vegetables hit the mainstream
It’s not really all that long since we brought together researchers on that overlooked portion of African agrobiodiversity that is its traditional vegetables for one of the first ever times. I wonder how many of us ever thought that in little more that 10 years we would be able to buy terere and managu and the like wrapped in plastic and barcoded in supermarkets in Kenya:
Or indeed buy nicely packaged and labelled seed from small agricultural suppliers in places like Limuru:
Preparation is time-consuming and fiddly, sure:
But the taste and nutrients are worth it, as more and more people are finding out. We had some Amaranthus for Christmas lunch, from grandma’s shamba. Can’t get much more mainstream than that.
(Not much) agrobiodiversity on display in Nairobi museum
The main building of the National Museums of Kenya in Nairobi has had a facelift, courtesy of the EU. Pretty good job on the outside, but the new exhibits were a bit of a disappointment.
There’s a big hall about Kenya’s animals, of course, and another series of displays about its cultures, arranged by life-stages (birth, youth, adolescence, initiation: you get the picture), though this includes very little about agriculture:
But there’s nothing at all on the country’s ecosystems and protected areas, and nothing on its plants, at least inside the building (apart from a display of an herbarium specimen in the small hall describing the museum’s history). There is a little botanic garden dedicated to medicinal plants (arranged by family, the wisdom of which is debatable), but this misses the opportunity of describing the Amaranthus on display as not just a medicinal but also a nutritious traditional leafy green (see my next post):
However, the entrance hall does have a terrific display of cucurbit diversity:
These bottle gourds are used by the Maasai and other pastoralists to store water, milk, blood, and mixtures thereof. Here’s a close-up:
