FIGURE 3.

Long-lasting priming of SA-dependent gene transcription. Levels of gene transcription were determined by RT-qPCR analysis of shoot tissues from water- and BABA-treated plants at 28 days after treatment (dat) with 40 mg/L BABA, and different hours (h) after spraying of the leaves with 0.5 mM SA. Data represent average fold-change values (±SEM) relative to expression levels before SA application. Asterisks indicate statistically different levels of expression between control- and BABA-treated plants (Student’s t-test; α < 0.05; n = 3).
