Isozyme polymorphisms in some ornamental mussaendas of the Philippines

Issue Date

1992

Abstract

An analysis of isozymes in selected ornamental mussaendas of the Philippines was conducted using starch gel electrophoresis in order to genetically differentiate the mussaendas from each other. Of the four enzyme systems resolved, namely malic enzyme, esterase, acid phosphatase, and isocitrate dehydrogenase, only the first was found to be non-polymorphic.

A total of four putative loci were found -- two in esterase, one in acid phosphatase, and another in isocitrate dehydrogenase. For esterase and acid phosphatase, two alleles were designated in each locus. For isocitrate dehydrogenase, there were three alleles in its locus. By using a combination of the four loci of the different enzyme systems, 10 of the 13 mussaenda cultivars can be genotypically differentiated from each other.
