Fig 4. Expression patterns of SlDEAD30 and SlDEAD31 genes under various stress treatments including NaCl (200 mM, A, D), heat (40°C) and cold (4°C, B, E), dehydration, and wounding (C, F).

Gene expression was detected by RT-PCR using total RNA from leaves or roots of 35-day-old tomato plants. Bars represent mean relative expression values ± SE (n = 3). Values are presented relative to untreated plants (0 h). Asterisks indicate a significant difference (P<0.05) between untreated and treated plants. The twofold threshold is indicated by a dotted line.
