Investigation of auxin from the stem cambial region of adult Pinus silvestris trees by diffusion to agar, and by extraction revealed both seasonal variation and gradients along the stem. Variation in dynamics of auxin efflux and the effect of the siz

Onion root tips were studied both with transmission and scanning electron microscope. The cells in the meristematic region of initials were found to be little vacuolated. At early stages of cell differentiation areas free of ribosomes are segregated

In the presented model cells of the plant body form a spatial medium in which three-dimensional morphogenic waves of auxin are propagated. Points in the same phase of oscillation form isophasic surfaces and the vectors of wave propagation form a thre

Basipetal efflux of natural growth substances from the cambial region of a successive series of short sections of the stem of Fraxinus excelsior L. was measured by Went's oat coleoptile curvature bioassay. A wave-like pattern of stimulation by natura

The proposed hypothesis concerns the transduction of auxin molecular signals arriving from the apoplast at the plasma membrane or recognized by the proteineous receptors of the responding cell, to the concentration gradients oscillating in the suprac
