Thioproline‐induced accumulation of proline in barley leaf sections
Abstract Treatment of barley leaf sections with 0.1 mol m−3 thioproline (L-thiazolidine-4-carboxylic acid) was found to induce a marked increase in proline together with some decrease in glutamate, whereas the levels of other andno acids were not influenced. This result is discussed in relation to the significance of the increase in proline in tissues treated with abscisic acid or subjected to water stress.
