Germplasm Phenotype:

• SALK_107193C  — dot3-2 mutants are dwarved plants with reduced fertility compared to wild type Arabidopsis plants.
• dot3-1  — dot3-1 mutants are dwarfed plants that have a parallel venation pattern defect in their leaves and abnormal vein loop patterns in their cotyledons. Primary root growth is significantly inhibited in dot3-1 mutants, but, they can produce lateral and adventitious roots.
