研究了激动素诱导的烟草愈伤组织两个克隆的干重、可溶性蛋白含量、δ-氨基乙酰丙酸脱水酶活性和叶绿素含量的变化。激动素在诱导变绿之前使非绿色组织的δ-氨基乙酰丙酸脱水酶活性显着增加。实验数据表明，在激动素诱导的非绿色烟草组织变绿过程中可能诱导特定叶绿体蛋白。激动素导致本研究中使用的绿色愈伤组织的δ-氨基乙酰丙酸脱水酶活性和叶绿素含量下降。
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.
