Abstract
Kinetin at a supra-optimal dose of 1.0 mg/l reduces the growth inhibitory effect of CCC at 5 × 10−2 M on tobacco callus and increases it on tobacco crown-gall. CCC increases the content of total, acid soluble, protein anti nucleic acid nitrogm in both tissues. Kinetin partially reduces the effects of CCC on nitrogem metabolism in callus tissue, and increases it in crown-gall. It is suggested that (1) CCC affects the synthesis of RNA directing the synthesis of protein, and (2) interaction of kinetin with CCC realizes via the genetic apparatus of the cell. Kinetin v supraoptimálni dávce 1,0 mg/l redukuje inhibicirüstu kalusu tabáku vyvolanou CCC 5. 10−2 M a zvětšuje tuto inhibici u hálky "crown gall". (Tab. 1, Fig. 1). CCC zvyšuje obsah celkového, v kyselině rozpustného, bilkovinnüho dusiku a dusiku nukle. ovÝch kyselin v obou pletivech. Kinetin částeěně redukuje ùčinek CCC na metabolismus dusiku v kalusu a zvyĆuje jej v "crown gall". (Tab. 3). Předpokládáme, 1) že CCC püsobi na synthesu RNK, řidici synthesu bilkovin a 2), že interakce CCC s kinetinem se uskutečАuje prostřednictvim genetického aparátu buАky. Кинетин в надоптимальной дозе 1,0 мг/л снижает подавляющее рост дсйствие ССС в конц. 5. 10-2 М на каллюс табака и повышает это подавление у галлы «crowngall» (табл. I, рис. 1). ССС повышает содержание общего, кислоторастворимог о, белковото азота и аэота нуклеиновых кислот в обсих тканях. Кинетин частичпо снимает действие ССС на обмен аэота в каллюсе и повышаст его у «crowngall» (табл. 3). Предполагастся, 1) что ССС действуег на синтез РНК, управляющей синтезом белков и 2) что взаимодействие ССС с кинетином осуществляется посредством генетическото аппарата клетки.This publication has 34 references indexed in Scilit:
