Interaction of microtubules and microfilaments in the zone of distal elongation of Arabidopsis thaliana roots

Investigations on GFP-MAP4 and GFP-ABD2 plants of Arabidopsis thaliana with the usage of inhibitors of actin and tubulin polymerization revealed that stability of cell growth in the zone of distal elongation of a root is provided by structural interactions between microtubules and actin filaments. The experiments with clinorotation and inhibition analysis enabled us to demonstrate that gravitation is a determining factor for the interaction between cytoskeleton elements in the zone of distal elongation in a root.
