Germplasm Phenotype:

• orm1 met/met orm2-/-  — Only survived in medium supplemented with sucrose, severely dwarfed, proliferation of small, deformed chlorotic leaves, plants persisted in a visually viable state for 20-25 days after planting; accumulated 3.7-fold more sphingolipids; lack of vacuolar turgor; chloroplasts round with marked disintegration of thylakoids and highly abundant osmiophilic structures that resemble plastoglobuli.
• orm1-/- orm2-/-  — High levels of ceramide; seeds nonviable, displayed aberrant embryo development, and had >80% reduced oil content.
