Phenotypes of transplastomic plants. (A) Phenotype under low-light conditions (30 μE m⁻² s⁻¹). (B) Phenotype under high-light conditions (1000 μE m⁻² s⁻¹). Note the less pronounced phenotype of the Δ intron 1 mutant, which is solely visible by a slightly delayed development and senescence (i.e. a darker color of the old leaves).
