Abstract
Investigations on Arabidopsis thaliana--GFP- MAP4 and A. thaliana--GFP-ABD2 plants treated with tubulin and actin inhibitors has shown that stability of cell growth in the distal elongation zone of plant root is achieved by structural interrelation of microtubules and microfilaments. Use of clinorotation and application of inhibitor analysis allowed us to show that gravity force defines the type of such interrelation.
