ABA and stress regulated gene expression post-stratification. Wild-type (Col or Ws) and mutant (abi4 and abi5-1) seeds were stratified for 3 days on minimal media (min) with or without either 5 μM ABA, 330 mM Glucose or 165 mM NaCl, then germinated for 24 h. RNA was extracted and transcripts were analyzed by Northern blot. a Comparison of Ws and abi5 seeds. b Comparison of Col and abi4
