Abstract

By parabiosis we have constructed Hydra that lack nerve cells but whose tentacles contain nematocytes (stinging cells). We were able to demonstrate that the nematocysts of these polyps can be triggered either mechanically or electrically. We conclude that nematocyst discharge in hydra does not require the presence of nerve cells.

The catecholamine-producing chromaffin cells of the American eel are strongly innervated by fibers, which, by ultrastructural criteria, seem to be cholinergic. However, neither removal of the brain nor removal of the brain combined with extirpation of the anterior spinal cord prevents the release of

Photosynthetic characteristics of transgenic tobacco (Nicotiana tabacum L.) plants with a soluble pyrophosphatase in the cytosol of their leaf cells were compared to those of wild-type plants. Although the development of the transgenic plants was somewhat retarded compared to the wild type, as shown
