Genetic Control and Linkage Relationships among Aminopeptidases in Maize.
Maize aminopeptidase is coded by four genes. Amp1 and Amp2 have been localized to chromosome 1. A three-point cross shows the gene order to be Amp2-15%-Amp1-33%-Adh2 (alcohol dehydrogenase). Amp3 and Amp4 assort independently of each other and of chromosome 1 aminopeptidases. Another linkage relationship among the maize genes Amy2 (amylase), Cat1 (catalase), and Amp3 exists, but the chromosome location has yet to be established unequivocally.
