Ethylene production and polyamine content of fully habituated sugarbeet calli


, : Ethylene production and polyamine content of fully habituated sugarbeet calli. Journal of Plant Physiology 143(6): 722-725

Compared with a normal (N) auxin- and cytokinin-requiring sugarbeet callus, two habituated (a nonorganogenic HNO and a self-shooting HO) calli, obtained from the same mother strain produced a very low amount of ethylene. Ethylene production by HO callus cells in the presence of 1-aminocyclopropane-1-carboxylic acid (ACC) was increased by about 20 times versus 3-fold for HNO cells. The polyamine content of HNO cells was very high compared with N cells, but that of HO was lower. The results are compared with literature data on hormone autonomous lines and shooty tumors. The possible interactions between ethylene and polyamine metabolism are also discussed.
