Northern-blot analysis of the expression of the Arabidopsis genes homologous to Esi47. Total RNA samples from roots or leaves of hydroponically grown Arabidopsis plants were analyzed. The plants were untreated or treated with 250 mm NaCl or 100 μm ABA for various durations, as indicated. The cDNA inserts from the EST clones for the Arabidopsis genes as indicated were isolated and labeled with ³²P as probes. The EST clones for the genes F8A24.12, F12E4.50, T7F6.28, AtP5CS1, and 18S rRNA are F3A9T7, 311H3T7, 193H7T7, FAFM64, and 40F8T7, respectively. The control probe, AtP5CS1, was used as an example of a previously characterized NaCl- and ABA-inducible gene.
