Germplasm Phenotype:

• spl7  — Hypersensitive to copper deficiency. Seedling growth is impaired when plants are grown in soils containing low copper levels (e.g. 0.1 micromolar).
• spl7-1  — Defective in response to Cu deficiency. Increased anthocyanin. Mutants grow poorly on Cu containing and deficient media and accumulate sugars. No response to addition of sucrose as measured by increase in biomass.
