Fig 6. Specific PP2A isoforms modulate early flg22 signaling.
Specific PP2A subunits differentially regulate flg22-induced reactive oxygen species (ROS) production. Leaf discs (6 mm in diameter) from 5-week-old plants of indicated genotypes were treated with 100nM flg22 or H2O and ROS production was monitored over-time. Data was normalized within each biological replicate with the average of highest relative light unit (RLU) value and the values preceding and following the peak value from flg22 treatment of Col-0 set to 100%. Shown are the averages of the normalized values of both the peak and the normalized values of the measurements preceding and following the peak from 3–6 biological replicates. * indicates a significant difference by Student’s t-test at P<0.05 comparing each genotype to Col-0.
