INHERITANCE OF ISOCITRATE DEHYDROGENASE, MALATE-DEHYDROGENASE, AND SHIKIMATE DEHYDROGENASE IN PEACH AND PEACH X ALMOND HYBRIDS Academic Article uri icon

abstract

  • Eighteen isozyme systems were surveyed in the peach [Prunus persica (L.) Batsch.] plant introduction collection. Seven systems were polymorphic. Three previously unreported isocitrate dehydrogenase (IDH; EC 1.1.1.41), three malate dehydrogenase (MDH; EC 1.1.1.37) and two shikimate dehydrogenase (SDH; EC 1.1.1.25) banding patterns were detected in the clones. Isocitrate dehydrogenase was dimeric in structure, with two alleles present at a single locus. Malate dehydrogenase was dimeric in structure, with three alleles present at the fast locus, while a second locus was monomorphic. Shikimate dehydrogenase was monomeric, with one allele present in most clones, while PI 113452, PI 113650, and PI 117679 were heterozygous for a slow SDH allele. Electrophoretic evidence suggests PI 113452, PI 113650, and PI 117679 are peach almond (P. dulcis Webb) hybrids, since they were heterozygous for alleles previously reported only in almond.
