SlRd2 and SlCipk6 transcripts highly accumulate after nacl and osmotic stress in tomato. A to E, y axis represents mean values of Q RT-PCR of three experiments, with three biological replicates in each. Error bars represent the se. The expression levels were normalized to SlActin2. Gene induction (fold increase) in infected or treated plants was compared with the expression level of control or mock inoculated plants at 0 h and is shown as relative expression, excepting in (A). A, SlRd2 transcript accumulates in tomato leaves, petioles, stems, flowers, and roots. Relative expression on y axis was compared with expression level in leaves. B and C, SlRd2; D and E, SlCipk6 mRNA accumulation in leaves during NaCl (B and D) and osmotic stress (C and E). Hydroponically grown tomato plants were treated with 100 mm NaCl (B and D) or 300 mm mannitol (C and E). OS, osmotic stress.
