<!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --> Transcriptome, proteome, and metabolome data are being developed for two experiments. In protocol number 1 a variable number of adult leaves are exposed to UV-B for a fixed time and responses measured in illuminated vs. shielded leaves and in immature ears. In protocol number 2, two leaves are exposed for 1, 2, 4 or 6 h with measurements on illuminated and exposed leaves plus ears. Controls are fully exposed and no UV-B greenhouse plants and field plants plus supplemental UV-B and shielded organs. The talk will concentrate on the RNA profiling data. The ultimate goal is to identify the mobile UV-B stress signal molecule(s).
