Germplasm Phenotype:

• CS68146  — Pale cotyledons and green true leaves in 14 day-old seedlings. Delayed seedling development.
• CS68147  — Pale green plants.
• CS68148  — Pale green plants.
• SALK_072931  — few flower development defects
• qwrf1qwrf2  — Severely deformed morphologies and symmetries of various floral organs as well as a significant reduction in the seed setting rate.
• sco3-1  — The sco3-1 mutation alters chloroplast morphology and development, reduces chlorophyll accumulation, impairs thylakoid formation and photosynthesis in seedlings, and results in photoinhibition under extreme CO(2) concentrations in mature leaves.
