Wiesner allows that circumnutation does exist in some cases. This last class he
considers a small one; he states, indeed, that “nearly all, especially the clearly
perceptible circumnutations," are combined movements belonging to the second
of ...

Rhythms in Plants: Phenomenology, Mechanisms, and Adaptive ...
The problem remains that there has been no direct evidence yet for the
involvement of the graviresponse as an external oscillator in circumnutation.
Indeed, this is rather controversial, as the following discussion demonstrates. The
hypocotyls ...

Plant Tropisms: And Other Growth Movements
Circumnutation derives from regular changes in the rates of cell elongation along
an organ (Fig. 1.3b). It is generally held that waves of differential growth move
basipetally down a circumnutating shoot (Johnsson 1979), although it has been ...
It has long been debated whether gravitropism and circumnutation are causally
related to each other (Kiss 2006). Interestingly, it appears that circumnutation and
winding movement defects in weeping could be attributed to loss of endodermal
...

Lectures on the Physiology of Plants
In his paper on the subject, which affords much valuable information as to the
mechanism of the process, Schwendener attributes twining to circumnutation and
to an antidromous torsion, that is, a torsion in an opposite direction to that of ...

Light- and Auxin-regulated Protein Kinases from Arabidopsis ...
Since gravitropism seems not to cause the wag phenotype, we hypothesized that
circumnutation might be altered. Roots from certain Arabidopsis ecotypes (Ler,
Ws) have a tendency to skew to the left (as viewed from above) as they grow ...
Aaron Andrew Santner, 2006
One rotation usually requires 1-2 h but both arc diameter and circumnutation rate
vary with species and environmental conditions. Basically, conditions that
promote vine growth also enhance circumnutation. The actual mechanism by
which ...
Francis E. Putz, Harold A. Mooney, 1991
