In structural terms, djenkolic has two units of L-cysteine joined through a CH2 group linked to sulfur atoms. It has also been found in seeds of Albizzia lophanta and Parkia speciosa32 and, as noted earlier, is the source of CS2 in Mimosa pudica (Section 11.1.2.2.2). An enzyme in A. lophanta seeds converted djenkolic acid to an unstable material with a leek-like odor, methylene dithiol 39.92 This was presumably an elimination of aminoacrylic acid 28 via intermediates 37 and 38 (Scheme 13). The methylene dithiol decomposed to H2S and possibly, thioformaldehyde, CH2S the latter might be a source for polysulfides.

The sensitive plant (Mimosa pudica) also undergoes a remarkable change in leaf shape triggered by mechanical touch (Fig. 2). A light touch or vibration produces a sudden drooping of the leaves, the result of a dramatic reduction in turgor pressure in cells at the base of each leaflet and leaf. As in the Venus flytrap, the drop in turgor pressure results from K+ release followed by the efflux of water.

Potassium channels can have a frequency of one or more channels per square micrometer of membrane surface area. Cellular control can be exerted on the opening of such K+ channels, because concentrations of cytosolic Ca2+ above 3 x 10-4 mol m-3 (0.3 p,M) can inhibit channel opening. Other ion channels in plant membranes are specific for Ca2+ or Cl-. Besides being sensitive to the electrical potential difference across a membrane, some channels apparently open upon stretching of a membrane. Also, many plant cells are excitable and can transmit action potentials, a process in which ion channels are undoubtedly involved. For example, action potentials have been measured for plants responsive to tactile stimuli, such as rapid leaf movements in Mimosa pudica and insectivorous plants (Dionaea spp., Drosera spp.), as well as along the phloem for many species. In addition, ion channels are involved in the long-term maintenance of specific ion concentrations in plant cells.
