FIG 3.

Changes in the transcript levels of genes involved in sucrose metabolism in response to salt stress. The transcript levels of spsA (A), spsB (B), sppA (C), susA (D), susB (E), invA (F), and invB (G) before (0 h) and at 30, 60, and 180 min after the addition of 50 mM NaCl were determined by qRT-PCR in the wild-type, DRorrAS, and DRsigB2S strains. The transcript levels were determined in duplicate measurements using three independently grown cultures. The transcript level at 0 min in the wild type was taken as 1. Data that represent a significant difference (P < 0.05; t test) between the wild type and DRorrAS (#) or DRsigB2S (§) are indicated.
