Chinese genebank in the top 10

The Chinese Academy of Science and Chinese Academy of Engineering voted for the country’s top 10 scientific achievements of 2007, and guess what? In at number 9 is the establishment of a genebank at the Kunming Institute of Botany.

After its completion, the resource bank will include a seed bank, vitro plant germplasm resource bank, DNA bank, and microbial seed bank. It will collect and preserve 190,000 copies (strains) of 19,000 varieties of germplasm resources.

The last genebank that got such press was you know what. No, wait, here’s another! Are genebanks the new black or something?

Apples unmoved

One of the bits of news we missed while we were resting and relaxing as hard as we were: the UK’s collection of apples and other fruits is staying at Brogdale. This may strike you as no-news news. It isn’t.

Long-standing readers will remember that the UK government put management of the site out to tender, and that two of the proposals required moving the entire collection to a new site. This seemed like a slightly daft idea, at least from our perspective. So it is good to relate that the management contract was awarded to Reading University, who will be leaving the collection where it is.

The Visitor Centre and sales areas are being expanded, and it could be that the collection is now poised to play a more important role in spreading the good news about all those fruit varieties that aren’t available in little plastic bags in the supermarket.

It has been a long and complex struggle, and it is not clear what the future of the Brogdale Horticultural Trust. We’ll try and keep informed.

A mighty wind

My recent post about lighting strikes in a coconut genebank was picked up by the excellent Coconut Google Group and generated some interesting responses. In particular, there’s a comment from Charles Clement of the National Institute of Amazonian Research in Manaus, Brazil recounting how a high-velocity wind blast — an Amazonian wind storm — took out a large chunk of his peach palm (Bactris gasipaes) genebank. Ex situ conservation in field genebanks can be a risky business indeed. The solutions are clear: more replications within collections, cleverly distributed in space; safety duplication of the entire collection somewhere else entirely (in vitro or as seeds as appropriate); and complementary conservation in situ. But that all costs money. I would say that most food crop accessions maintained in field genebanks around the world are unique. Take coconut. The Coconut Genetic Resources Database records 1416 accessions from 28 genebanks in 23 countries. More than 600 of them are represented by a single accession.

Seed conservation: cold, or dry?

Another fine guest post from Jacob van Etten.

Places with extreme conditions are good for conservation, whether it be Timbuktu with its dry, hot climate for books or Spitsbergen with its freezing cold for crop seeds. Next year the seeds will start to come to Spitsbergen from across the world to stock the “doomsday seed vault”. Right now the vault is being cooled down, to be reaching -18°C soon.

Low temperatures are key to ex situ conservation of seeds. Cold chambers and freezers stuffed with seeds are found near any plant scientist around the world. The Svalbard project is not only unique because of the size of the vault but also because of its location. The low temperatures on the island will make the vault less expensive to cool as well as less vulnerable to energy failure, a common preoccupation of seed bank managers in those countries where tropical temperatures, unreliable energy networks and unpaid bills tend to converge. An alternative solution, however, seems to be on the horizon. The latest Technology Quarterly section of The Economist runs an interesting story about dry storage of biological materials at room temperature. Wrapped in polymers or sugars, DNA molecules are less vulnerable to degeneration. Perhaps this technology will also be available to seeds some day?
