National Geographic’s eight-month series on food has caught up with Colin Khoury’s blockbuster paper on how many crops feed the world. The infographic on diet similarity looks ok on the printed page, I guess:
But it’s way cooler online.
Big rice data portal
You remember the 3000 rice genomes project? You know, the one that represents the future of genebanks? Well, if you were wondering which 3000 accessions were actually chosen for sequencing, you can get that information, and much, much more, on the new website of the International Rice Informatics Consortium. Happy browsing. Well, maybe not on this page, which seems to need some work.
Focusing on genebanks for climate change adaptation
The Focused Identification of Germplasm Strategy (FIGS) has been the subject of a fair number of posts here in the past couple of years. It has now clearly hit the big time, with a major workshop which got picked up by the BBC, no less. The latest paper to feature this strategy for more effectively mining genebank collections for the material you really want features the search for drought adaptation in faba beans.
Meanwhile, another workshop reminds us that breeding new varieties using the stuff you find in genebanks is just one way of adapting agriculture to climate change:
…there are various agricultural practices to offset the adverse effects of climate change on crop production and soil, such as mulching, that will help with water conservation and soil fertility, and crop rotation, which contributes to sustainable cultivation.
Strategizing about conservation of horticultural crops
Another report from one of our correspondents at the International Horticultural Congress:
There were some great discussions during the IHC’s workshop on global conservation strategies for horticultural crops. Few of these exist, and even fewer have actively been implemented. The participants heard from several speakers about the state of development and implementation of the strategies on citrus, strawberry, apple and banana. It appears that the banana strategy, which is currently already in its first revision, is the furthest along the road of implementation — largely thanks to the support of MusaNet. Having the backing of the conservation and use community of a particular crop is key for the development and success of a strategy — and it helps if the community is already organized in some shape or form. The fact that many horticultural fruit crops are not on Annex 1 of the ITPGRFA can really hamper the development and implementation process of global conservation strategies (in fact, so far there are no global conservation strategies for crops which are not on Annex 1) and several participants felt that horticultural crops deserve more recognition under the Treaty.
Freeing the banana
By freeing Musa balbisiana of infectious eBSV, virologists are once again friends with #banana breeders says Pierre-Yves Teycheney #IHC2014

Well, that sounds teasingly intriguing. Fortunately, we have a mole at the relevant symposium of the International Horticultural Congress in Brisbane. Here’s his brief report from the trenches:
Great talk also by Pierre Yves Teycheney, who together with his colleagues at CIRAD seems to have found a way to deal with the problem of the endogenous Banana Streak Virus that is embedded in the Musa B-genome. Since its discovery this virus had essentially brought to a halt CIRAD’s inter-specific hybrid breeding program, and prevented distribution of any hybrid materials that contained the B-genome. Luckily, an allelic difference was detected that renders the virus non-infectious, so researchers at CIRAD managed to develop B-genome materials (through traditional approaches but also doubled haploids) that are homozygous for the non-infections alleles and ‘voila!’ derived non-infectious material is now again flowing through CIRAD’s interspecific hybrid breeding program!
Keep it coming, people!
