2006 Annual Report 4d.Progress report. This report serves to document research conducted under a Specific Cooperative Agreement between ARS and University of California, Berkeley. Under the Specific Cooperative Agreement, University scientist working at ARS showed that the OXS2 gene induces flowering in response to stress, by binding to the promoters of two floral integrator genes and activating their expression. The OXS2 protein may be harnessed for the stress-induced activation of site-specific recombination through activation of target promoter-recombinase gene constructs. Additional details of research can be found in the report for the parent project (5335-21000-031-00D).
