Stress-induced expression of IDA/IDL and PIP/PIPL genes based on qRT-PCR. Two-week-old plants were subjected to the following treatments for 6h unless otherwise specified: 10 μg/ml chitin (1h), 150mM NaCl, 10 μg/ml CHX and 15 μg/ml anisomycin. Infestation with Brevicoryne brassicae was done on 23-day-old plants, and rosette leaves were harvested after 72h (34). n=3. The relative expression (log2 ratios) values between treated and mock-treated samples are given next to the colour scale. Statistical differences between treated and mock-treated plants are indicated, where a diagonal line indicates no significance (REST analysis; P>0.05), and no diagonal line indicates significant difference (REST analysis; P<0.05). Brv, Brevicoryne brassicae; Salt, NaCl; CHX, cycloheximide; ANI, anisomycin.
