摘要：

In order to reveal the involvement of tubulin microtubules and actin microfilaments in gravisensing reactions in the distal elongation zone of root, Arabidopsis thaliana plants stably transformed with MAP4-GFP construct were grown under slow clinorotation. Experiments have shown that stabilization of cell growth in the distal elongation zone of Arabidopsis seedling root is provided by common structural organization of microtubules and microfilaments, and interrelations between microtubules and microfilaments is highly dependent upon the type of cell differential growth. Less pronounced effect of microfilament disruption on microtubule organization has been observed under clinorotation and it suggests the existence of complex mechanism of cooperation between microtubules and microfilaments which is probably, masked on earth.
