Quick, the AmJBot Special Issue on the applications of next-generation sequencing in botany is officially out, and some of the papers are actually free! Including the one on genebanks. And yes, I haven’t forgotten I promised to blog about it. But there’s rather a lot of it to digest…

The Origins of some basic mistakes about genebanks
I’m not sure how we missed it, but Origins, “a project of the Public History Initiative and eHistory in the History Department at The Ohio State University,” had a longish piece called “Conserving Diversity at the Dinner Table: Plants, Food Security and Gene Banks” last month. You can read it, or listen to it. The author is Nurcan Atalan-Helicke Visiting Assistant Professor of Environmental Studies at Skidmore College, Saratoga Springs, NY.
It’s a pretty straightforward account of the practice and history of crop diversity conservation and use, but with a clear slant.
In the long run, the most efficient way to conserve agrobiodiversity is to maintain farmers’ cultivation of traditional varieties.
Admittedly, there’s not much evidence brought forward for this statement, which is treated almost as self-evident, but it is not made any easier to swallow by being preceded by the likes of this:
The Soviet Union was the first to establish gene banks for crops. However, Russian botanist Nikolay Vavilov’s effort to collect seeds worldwide in the 1920s and 1930s was aimed at research alone, not the protection of seed diversity.
I feel sure Vavilov would beg to differ. Or this:
Working in collaboration with hundreds of governments, civil society organizations, and private businesses around the world, CGIAR today supports 15 international centers for agricultural research and about 1,750 gene banks. Together, these gene banks contain a total of 6 million accessions of all crops and represent 95 percent of all cereal landraces worldwide. These are public or non-profit entities whose goal is to sustain “food for people.”
The bit about the CGIAR’s 1,750 genebanks will come as a bit of a shock to the CGIAR. Not to mention the 1,750 genebanks. Then there’s this:
The CGIAR gene banks are located primarily in the global South but their funding and guidance comes primarily from Northern donors. CGIAR ensures that seeds and plant germplasm are stored in duplicate and kept below freezing so that they can remain viable for decades. They are cultivated under sterile conditions with fertilizers.
Sterile conditions I suppose refers to in vitro collections. But what’s with the fertilizers? And also:
There is also a question of access. Whereas many of the CGIAR centers are open access resources, the newer ones are not. Both the Svalbard and the Millennium Seed Bank are more restrictive, with access limited to those with permission from countries that make deposits.
Well, actually, in the case of Svalbard, it is only the depositing institutes which can access the material they send up there for safe-keeping.
I could go on. Plus there’s no mention of the International Treaty on Plant Genetic Resources for Food and Agriculture. The mistakes and omissions are a pity because Dr Atalan-Helicke makes a couple of astute points. For example:
Many countries continue to depend on CGIAR’s gene banks to improve their agriculture, taking advantage of the CGIAR’s open access to resources for research, breeding, conservation, and training. Between 1974 and 2001, Kenya and Uganda received a total of 12,000 unique accessions from all CGIAR gene banks that were collected from other countries. In the same period, about 4,000 accessions collected from Kenya and Uganda were distributed to the world.
You rarely see this kind of statement about the value of the international collections in pieces which are trying to make the point that yes, sure, genebanks are ok, but there’s a better way to conserve crop diversity.
Anyway, if the Public History Initiative ever does another piece on agricultural biodiversity, we’d be happy to do the fact-checking.

- Heritable genome-wide variation of gene expression and promoter methylation between wild and domesticated chickens. Domestication was Lamarckian.
- Global economy interacts with climate change to jeopardize species conservation: the case of the greater flamingo in the Mediterranean and West Africa. Financial crisis leads to closing down of Mediterranean saltpans, which is not good news for flamingo. Climate change doesn’t help. Must be similar examples for plants, Shirley.

- Ecological and human impacts on stand density and distribution of tamarind (Tamarindus indica L.) in Senegal. Climate change will lead to an area of currently low density in the NW being a refugium. Connectivity problems will ensue.

- A short history of Lagenaria siceraria (bottle gourd) in the Roman provinces: morphotypes and archaeogenetics. Out of Asia. And more.
- Functional Properties, Nutritional Value, and Industrial Applications of Niger Oilseeds (Guizotia abyssinica Cass.). It has them, in spades, as this paper summarises.
- Sex at the origin: an Asian population of the rice blast fungus Magnaporthe oryzae reproduces sexually. The Himalayan foothills would seem to be the place where to look for resistance.
- Evolutionary History of Pearl Millet (Pennisetum glaucum [L.] R. Br.) and Selection on Flowering Genes since Its Domestication. Bayesian modelling of 20 random genes supports domestication about 4,800 years ago, with protracted introgression from the wild relative, and selection sweeps suggest flowering related genes unsurprisingly underwent strong selection as the crop spread southward. But a single domestication scenario? Anyway, sounds familiar, doesn’it.
- Genome-Wide Analysis of the World’s Sheep Breeds Reveals High Levels of Historic Mixture and Strong Recent Selection. Much like, ahem, pearl millet. For flowering genes, read horniness genes. The bit about an initially broad sampling of diversity sounds a bit like the horse. Who out there is going to synthesize all this domestication stuff? Not that I’m looking for a meta-narrative, mind.
- Ultra-barcoding in cacao (Theobroma spp.; Malvaceae) using whole chloroplast genomes and nuclear ribosomal DNA. Well, sequence the whole thing and be done with it is what I say, why flaff around with ultra-this and super-that?
- The crop yield gap between organic and conventional agriculture. 20%.
- Marcela, a promising medicinal and aromatic plant from Latin America: A review. Achyrocline satureioides, in the Asteraceae. Yeah, I never heard of it either. But these guys say it’ll make you rich and beautiful.
- Comparative genetic structure within single-origin pairs of rice (Oryza sativa L.) landraces from in situ and ex situ conservation programs in Yunnan of China using microsatellite markers. 2-5 times more unique alleles in the in situ version of various landraces compared to the ex situ version, collected in 1980. But same number of common alleles.
- Mutualism breakdown in breadfruit domestication. More recent cultivars have less abundant and less species-rich arbuscular mycorrhizas.
