Professor Paul Jarvis at the Department of Plant Sciences and his team have discovered a new biochemical pathway in plants which they have named CHLORAD.
By manipulating the CHLORAD pathway (from “cloroplast-associated protein degradation”), scientists can modify how plants respond to their environment. For example, the plant's ability to tolerate stresses such as high salinity can be improved.
Jarvis said, “Two decades on from the identification of the chloroplast protein import machinery which delivers new proteins to chloroplasts our discovery of the CHLORAD pathway reveals for the first time how individual, unwanted proteins are removed from chloroplasts.”
The researchers hope that their results, published in Science, will open the way to new crop improvement strategies, which will be vital as we face the prospect of delivering food security for a population that is projected to reach nearly 10 billion by 2050.
