Abstract
Kinetin-induced changes in dry weight, soluble protein content, δ-aminolevulinic acid dehydratase activity, and chlorophyll content of two clones of Nicotiana tabacum L. callus were studied. Kinetin brought about a marked increase in the δ-aminolevulinic acid dehydratase activity of nongreen tissue just before induction of greening. The experimental data suggested a possible induction of specific chloroplast protein(s) during the kinetin-induced greening of nongreen tobacco tissue. Kinetin caused a decline in the δ-aminolevulinic acid dehydratase activity and chlorophyll content of the green callus used in the present study.Keywords
