Germplasm Phenotype:

• CS72318  — Virescent mutant phenotype; decreased photosynthetic activity and pale green leaves, especially in younger leaves. Strong growth retardation. Large, rounded chloroplasts, intactness compromised. Plastids appear to be swollen with disorganized thylakoid membranes and low abundance and reduced size of starch granules.
• CS72319  — Virescent mutant phenotype, pale green leaves. Strong growth retardation.
• CS72520  — Seedlings are light sensitive and have low survival rates.
• CS72521  — Seedlings are light sensitive and have low survival rates.
• CS72656  — partial recovery of kea1-1kea2-1 double mutant (CS72318) phenotype (impaired photosynthesis, pale green leaves, stunted growth)
• CS72657  — partial recovery of kea1-2kea2-2 double mutant (CS72319) virescent and stunted growth phenotype
• CS73252  — In addition to the rumpled leaf surface reminiscent of msl2 mutants, the double mutant shows variegated leaves and an even more significant growth deficit.
• CS73253  — In addition to the rumpled leaf surface reminiscent of msl2 mutants, the double mutant shows variegated leaves and an even more significant growth deficit.
• kea1-1 kea2-2  — Reduced growth and pale yellowish leaves. Reduced photosynthetic protein complex accumulation.
