US$14 million for genome studies

plant1_f.jpgThe National Science Foundation in the US has announced grants totaling US$14 million for genome studies of “economically important plants”. Among the many projects will be one on red rice (seen left, photo courtesy of Washington University St Louis), a weedy variant that contaminates rice fields in the US. It reduces yields by up to 80% and researchers hope to discover whether it originated from cultivated rice or was imported, possibly accidentally, as a weed from Asia. A similar study will focus on weedy versions of radish. This could lead to a deeper understanding of just what makes some populations weedy and invasiveness, and hence to better control. One the other hand, maybe they should just develop a local market for red rice.

Other studies will look at genetic variation within cultivars of maize and pine trees and at the evolution of Brassicas, a highly diverse group. One can only hope that the information gathered will also help farmers and scientists to produce better adapted varieties for their own conditions, even if those conditions are far removed from the intensive agricultural fields of the US.

Micropropagating sweet potatoes

According to the Carolina, USA farmer featured in this article, “micropropagation is the name of the game in sweet potatoes.” “The bottom line is a very uniform crop,” he adds. That’s not necessarily everywhere a good thing, of course, but clean planting material is always important.

Conserving animal genetic resources in Vietnam

A CIRAD project is using both somatic cloning and in situ approaches to conserve genetic resources of various threatened useful wild animals (including livestock relatives) in the highands of Vietnam. GIS is also being used to map genetic diversity as measured by molecular markers. The results will be extended to prepare a conservation strategy for the region as a whole.

Biomass and bio-energy

We alluded last week to a new paper showing that prairie grasses are a far better source of biomass for energy than anything else currently around. There’s obviously a lot to be said, but rather than clutter up the pages here (our goal is two longer articles a month) I decided to use my own blog to publish a slightly closer look at bio-energy and to link from here to there. So what are you waiting for, go on over and read it. I’ll add links to the other parts as I publish them there.

Tissue culture in Africa and the Pacific

A somewhat confusing (to me at least) article on SciDev.Net promises a new African collaborative initiative on plant breeding in the title, but delivers something quite different in the text. It seems that a network is being set up in East and Central Africa to promote the adoption of tissue culture for conservation, multiplication and exchange of genetic resources, presumably mainly of vegetatively propagated crops. Dr Mary Taylor of the Secretariat of the Pacific Community’s Regional Germplasm Centre has recently organized a similar network in the Pacific. Perhaps the two networks could collaborate?
