Published in the journal Nature earlier this month, the study shows how the peptide CLE25 is synthesised in the roots of plants when under stress due to a lack of water in the soil, resulting in the closing of pores (stomata) in the leaf surfaces.
Charis Cook works for GARNet, a BBSRC-sponsored network that supports plant scientists in the UK by, among other things, linking researchers to each other and to the research councils, and providing an information hub for plant scientists. GARNet also has its own blog. Before working for GARNet, Charis was at Royal Holloway, University of London, as a post-grad student and then a post-doctoral researcher.
