Germplasm Phenotype:

• SALK_124398  — Increased sensitivity to oryzalin, roots significantly shortened.
• lpa1  — The leaves of the mutant are paler than those of the wild type, and growth is significantly reduced. The leaf area of the mutant is ~75% lower than that of wild-type plants 26 d after germination.
• lpa1  — The mutants have defects in energy transfer within PSII or a partial loss of PSII capacity.
• lpa1  — The relative amounts of the PSII core subunits CP47, CP43, D1, and D2 is greatly reduced in the mutant, especially the PSII dimer.
• lpa1  — Wild-type chloroplasts are larger than those of the mutant and have a larger number of discs per grana stack on average. In addition, the wild-type chloroplasts display well-developed membrane systems composed of grana connected by the stroma lamellae, but the thylakoid membrane systems in mutant chloroplasts are disturbed, and the membrane spacing is not as clear.
