Abstract

Three electrophoretic variants of the peroxidase b isoenzymes in Petunia have been found. The encoding gene prxB is shown to be located on chromosome I by its linkage with the gene Hfl. Analysis of prxB heterozygotes showed a gradual increase of the electrophoretic mobility of all three PRXb allozymes during development and differential expression in enzyme activity of three prxB alleles. The location of prxB on chromosome I was confirmed by an allelic dosage effect in trisomies I, trisomie segregation and the construction of trisomies I with triple-banded PRXb phenotype. From telotrisomic analysis it was concluded that prxB and Hfl are located on the same arm of chromosome I. The unexpected linkage of prxB and Hfl with the gene Fl in one of the crosses was suggested to be caused by a translocation in line SI, involving the gene Fl.
