Mexico City protects maize landraces

In an almighty panic about GM maize, the government of Mexico City has sprung energetically into action. The result is a “Declaration of Protection of the Maize Breeds of the Mexico Altiplano.” There are said to be “more than 60” maize landraces in the part of the Altiplano that falls within the confines of the Distrito Federal, which I assume is the area over which the Declaration will be applicable.

The Declaration includes provision for:

  • establishing a research programme to improve local maize breeds
  • supporting farmers who sow only native seeds
  • promoting the use of organic fertilizer and pesticides
  • banning of the purchase and distribution of transgenic maize in Mexico City
  • establishing a germplasm bank for the Altiplano’s maize seeds

I have a few questions about all this, but I’ll just pose one here. Has anyone asked the CIMMYT genebank, just outside Mexico City, whether by any chance it already has the Altiplano’s maize landraces?

Good news for wheat

Two studies out in the past week in Science are going to help wheat breeders fight diseases. One identified a DNA sequence — for a product known as the Lr34 transporter protein — which seems to confer protection against no fewer than three fungal diseases. And another study showed that a (different) DNA segment (called Yr36), which had previously been introgressed into durum wheat from wild emmer, also conferred rust resistance in the field (via). Gene discovery strikes again.
