The effect of temperature upon the bioelectric potential across the plasma membrane in cells of tepals of Eranthis hyemalis (L.) Salisb. (Winter aconite) is described. Rapid warming of an intact tepal resulted in a transient small increase in the mag

We provide a 3D ultrastructural analysis of the membrane systems involved in tip growth of rhizoids of the green alga Chara. Electron tomography of cells preserved by high-pressure freeze fixation has enabled us to distinguish six different types of

While there is ample evidence for a role of auxin in root gravitropism, the seeming rapidity of gravi-induced changes in electrical parameters has so far been an argument against auxin being a primary signal in gravitropic signal transmission. To add

The positioning and gravity-induced sedimentation of statoliths is crucial for gravisensing in most higher and lower plants. In positively gravitropic rhizoids and, for the first time, in negatively gravitropic protonemata of characean green algae, s

Gravitropic bending of Lepidium roots caused by intermittent stimulation lasting approximately 1 h was the same for a particular sum of stimulation intervals and was independent of (i) the length of a single stimulation interval (from 1 to 12.2 s) du

In order to study the effect of mechanical stimulation on the membrane potential (Em) of roots of Lepidium sativum L., the roots were subjected to pulses of perfusion medium expelled from a micropipette positioned 1 mm from the root surface at the le

At low light intensities (less than 50 /anol m 2 s ') illumination evokes transient depolarization of membrane potential in mesophyll cells of the leaf-trap of Dionaea muscipula Ellis. Darkening causes hyperpolarization approximately symmetric to the

To determine the range of the threshold acceleration (a-threshold) for the gravitropic stimulation of Lepidium sativum L. roots and hypocotyls, experiments were performed on a centrifuge-clinostat with two-orthogonal axes. The rotation rate of the cl
