title: Genetics of the peroxidase isoenzymes in Petunia : Part 1: organ specificity and general genetic aspects of the peroxidase isoenzymes.
abstract: The peroxidase system in Petunia can be separated into a considerable number of bands by starch gel electrophoresis. The electrophoretic pattern obtained is not only dependent on the genotype of the plant but also on the organ investigated, the state of development of that organ, and the age of the plant. Several structural and regulatory genes seem to be involved in the production of the peroxidase isoenzymes. In Petunia at least three structural genes can be distinguished by their independent segregation. It is suggested that a few more structural genes code for the peroxidase isoenzymes in Petunia. In addition, post-transcriptional modification may contribute to the number of peroxidase isoenzymes.
