Phytohormone levels in roots and leaves of Arabidopsis seedlings after exposure to
for two or six days. The roots and shoots of the seedlings were harvested at day 0, 2 and 6 after exposure to the P. indica plug or an agar plug without mycelium. SA, ABA, JA, cis-OPDA and JA-Ile levels were determined. The values are means ± SEs of 4 independent biological experiments with 5 replications in each experiment.
