Fig 9. GUN1 contributes to chloroplast protein homeostasis and is required for survival of PGE-defective mutants.

(A) Resistance of WT and gun1-101 plants to the indicated inhibitors estimated as CHL level of plants germinated and grown in the presence of 15 μM LIN, 30 μM FSM or 35 nM NFZ relative to no-inhibitor controls. Data correspond to the mean and SEM values of n≥3 independent experiments. (B) Phenotype of 10-day-old WT and mutant lines of the indicated genotypes grown in the same plate. Bar, 5 mm.
