Plants that recognize a pathogen induce both a local defense response and a long-lasting, broad spectrum disease resistance throughout the plant, termed systemic acquired resistance (SAR). In the December Nature Genetics Maleck et al. use microarrays to monitor transcriptional changes during development of SAR (Nat Genet 2000, 26:403-410). Of the 10,000 expressed sequence tags (ESTs) on the microarrays, representing 25-30% of all genes from Arabidopsis thaliana, 413 show changes of 2.5-fold or m
