Proline Fed to Intact Soybean Plants Influences Acetylene Reducing Activity and Content and Metabolism of Proline in Bacteroids

Yuxian Zhu; Georgia Shearer; Daniel H. Kohl PLANT PHYSIOLOGY 1992. doi:10.1104/pp.98.3.1020

Other claims from this paper (14)

Intervention effect Root-supplied proline stimulated acetylene reducing activity as much as succinate.
Association Bacteroid proline dehydrogenase activity correlated strongly with acetylene reducing activity.
Intervention effect Proline content in host cytoplasm rose about threefold after 24 hours.
Intervention effect Bacteroid proline content rose about eightfold after 24 hours.
Observation Bacteroid proline concentration was calculated to be at least 3.5 millimolar.
Observation Radiolabeled proline and its products accumulated in host cells and bacteroids.
Observation Tritium-labeled proline was found in host cells and bacteroids.
Observation Labeled pyrroline-5-carboxylate appeared in bacteroids but not host cells after two hours.
Observation After 24 hours, labeled pyrroline-5-carboxylate occurred in host cells at about half its bacteroid quantity.
Mechanism Proline crossed both plant and bacterial membranes under the experiment conditions.
Mechanism Proline may supply energy for bacteroid functioning.
Intervention effect Proline did not rescue acetylene reducing activity in stemgirdled plants.
Intervention effect Succinate rescued acetylene reducing activity in stemgirdled plants.
Mechanism Succinate, but not proline, may reach nodules by a nonphloem route.

Proline Accumulation in Water Stressed Cotton Leaves¹

B. L. McMichael; C. D. Elmore Crop Science 1977. doi:10.2135/cropsci1977.0011183x001700060022x

Other claims from this paper (5)

Intervention effect Free proline in cotton leaves rose to about 100 times well-watered controls as water stress increased.
Observation The predawn leaf water potential threshold for proline accumulation was about —15 to —17 bars.
Intervention effect Total proline content increased during cotton water stress.
Intervention effect Free glutamic acid decreased during cotton water stress.
Recommendation Free proline is judged a poor indicator of the onset of cotton water stress because it accumulated only after severe deficits.
