[Isoenzyme variants of acid peroxidase in the genus Stachys]

Isozyme patterns of acid peroxidases and their dependence on plant age, cultivation conditions, and tissue type have been investigated by electrophoresis in polyacrylamide gel in four species of the genus Stachys. The most stable peroxidase patterns have been found in the plant roots. Acid peroxidases have been shown to be species-specific, which allows their use in taxonomic studies. Cultivation in vitro and in vivo produces different isozyme patterns in various tissues of plants of various ages.
