The effect of kinetin on cytochemical localization of Mg++ dependent ATP-ase in isolated lupine cotyledons

Roman Przymusiński, Adam Woźny, Fortunat Młodzianowski


ATP-ase activity stimulated with Mg++ ions was localized cytochermically in lupine cotyledons. Studies were also made of the effect of kinetin on this activity. Activity of Mg++ dependent ATP-ase was observed in plasmalemma, nucleus, nucleolus, endoplasmic reticulum, thylakoid membranes, prolamellar bodies, cell wall, and irilter-cellular spaces. Kinetin (6-furfurylaminpurine) used in the experiment, stimulated ATP-ase activity, but dad not affect its localization.
