Abstract
Mutants of Amaranthus edulis lacking PEP carboxylase and others containing varied amounts of the enzyme protein will be studied to establish the role of the enzyme in C4 photosynthesis. The ability of the plants to assimilate CO2 in varying environmental conditions will be investigated. Compensatory changes in the regulations of PEP carboxylase and other key enzymes will be compared to the levels of metabolites present in the leaves. The degree of recycling of CO2 and ammonia derived from photorespiration during C4 photosynthetic CO2 assimilation will be studied in a mutant deficient in glycine decarboxylase.
