A 33‐kDa protein component of the oxygen‐evolving complex in photosystem II is essential for photosynthesis, and it has been believed that mutants with deletion of this 33‐kDa protein are not found in higher plants. We report here the first isolation of an Arabidopsis thaliana mutant with a defect in one of the genes for the 33‐kDa proteins, psb O, and an intact gene ( psb O2). This mutant showed considerable growth retardation, suggesting that there is a functional difference between psb O and psb O2.
