Current status of the problem of the mechanism of gravity reception in plants.
Basic work carried out recently on the role of the structural-functional condition of cell organelles in the development of geotropic reaction in higher plants is reviewed. On the basis of analysis of theoretical proposals and experimental investigations of the molecular mechanism of perception and realization of the gravity stimulus, a hypothesis was developed that the key factor in the development of geotropic reaction is an interaction of cell organelles with membranes of the endoplasmic reticulum as a result of their sensing the gravity stimulus.
