  1. Plants were grown in the greenhouse under control (380 ppm CO2) and 700 ppm CO2 + drought. Using the STDGE-tool kit from GenXPro data were filtered for the terms Ambrosia, ragweed, pollen, extensin, exine, intine, cell wall, coat, allergen and the Allfam database. Known allergenic proteins in Ambrosia are shown in bold.
