| Abstract/Contents: | "Cell suspension cultures of the halophyte, Distichlis spicata, were stress with 200 ml of MaCl. Cells, protoplasts, an vacuoles of the stressed cultures were isolated and then assayed for proline content. Protoplasts and cells of stressed cultures were found to contain equivalent amounts of proline, while isolated vacuoles were found to contain no measurable amounts of proline. The osmotic contribution of cytoplasmic proline was equivalent to the osmotic stress induced by the NaCl in the growth medium. This method of analysis contributed additional direct evidence to the role of proline an osmoregulatory mechnism, and its localization in the cytoplasm. These observations also contribute further evidence to the argument that in some plants, especially halophytes, proline accumulation is an adaptive mechanism." |
