The structural gene prxE, coding for a slow cathodic peroxidase in Petunia, has been located to chromosome II, linked to F1. The presence of two mobility alleles in Petunia hybrida can be ascribed to its hybrid descent. Some properties of peroxidase e are mentioned. A gene prxJ is postulated for a still slower cathodic band. The gene Rp1, regulating the onset of expression of the allele prxB2, has been located on chromosome VII (gene order Rp1-prxF-An4). A synopsis of the isoperoxidases and the corresponding genes is given.
