Characterization of higher order mutants of pgdh3 with either pgr5 or pam68lpam68l. A 14-day-old plants grown under standard growth conditions. While pgdh3pam68l appears similar in size and color to Col-0 and single mutants, pgdh3pgr5hope1, and pgdh3pgr5-Cas#1 lines are not only smaller but also pale green. B Fv/Fm determination for single and double mutant lines. Mean, ± SD, N = 9, P < 0.05. C PIFT measurement of 3-week-old plants of the genotypes Col-0, pgdh3-1, pgdh3pam68lpam68l, pgdh3pgr5hope1, and pgdh3pgr5-Cas#1. The dotted red line indicates the Col-0 F0 peak in PIFT. Mean, ± SEM, N = 9. D, E Non-Photochemical-Quenching (NPQ) induction curve measured at 110 PAR for Col-0 (filled squares), pgdh3-1 (filled circle), pam68l (filled hexagon), pgr5hope1 (empty triangle), pgdh3pam68l (half-filled hexagon) and pgdh3pgr5hope1 (half-filled circle). Mean, ± SD, N = 6–9. F, G OJIP curves were taken with the standard Dual-PAM protocol for the different genotypes. Col-0 (black), pgdh3-1 (blue), pam68l (purple), pgr5hope1 (red), pgdh3pam68l (pink) and pgdh3pgr5hope1 (green). MEAN, N = 6.
