title: Genetics of the peroxidase isoenzymes in Petunia : 7. The alleles prxA6 and prxA7.
abstract: Two alleles of the structural gene prxA from Petunia, prxA6 and prxA7, could be identified by their differential temporal expression. The alleles prxA6 and prxA7 code for peroxidases with a similar electrophoretic mobility as the products of the previously described alleles prxA1 and prxA5, respectively. The former two alleles differ in that they have a different temporal expression with regard to the temporal expression of the allele prxA2. Crossing experiments indicated that the mutations involved are (cisacting) internal site mutations. In the case of the allele prxA6, the experiments indicated a difference with respect to the allele prxA1 in responsiveness to the action of a trans-acting factor.
