(A) Relative levels of DhAHP transcript of D. hansenii and its RNAi transformant as affected by salt. Cells were grown on YM11 media containing 2.5 M NaCl for 72 min, and their DhAHP transcripts determined by real-time RT-PCR. (B) Growth of D. hansenii and its DhAHP RNAi transformant. Cells were grown on YM11 media with or without 2.5 M NaCl. W: wild type strain, RNAi T: RNAi transformant. Data presented were means +/- S.D. from 3–4 replicates of measurement.
