Germplasm Phenotype:

• rpn5a-1  — Mutants display plieotropic effects on development. When grown in continuous light seedlings produce lanceolate shaped leaves with fewer numbers of cells. In long days- the rosettes are comprised of clusters of abnormally shaped leaves. Floral morphology is normal but the anthers do not shed pollen. Embryogenesis is defective. Mutant embryos are delayed in development and have fewer cells.
• rpn5a-2/rpn5b-2  — Cannot recover homozygous double mutant.
