Variant chloroplast fructose 1,6-diphosphate aldolases were found in Pisum sativum when 10 commercial varieties were examined for electrophoretically distinct species of chloroplast triose phosphate isomerase, phosphoglyceric acid kinase, glyceraldehyde 3-phosphate dehydrogenase, and aldolase. When reciprocal crosses are made, both aldolases appear in individuals in the F(1) generation. Backcrossing gives offspring having aldolases characteristic of the homozygous or of the heterozygous parent; the inheritance is therefore not maternal but Mendelian. Clearly this chloroplast reductive pentose phosphate cycle enzyme is under nuclear gene control in P. sativum.
