TL;DR: In this article, a simple colorimetric determination of proline in the 0.1 to 36.0 μmoles/g range of fresh weight leaf material was presented.
Abstract: Proline, which increases proportionately faster than other amino acids in plants under water stress, has been suggested as an evaluating parameter for irrigation scheduling and for selecting drought-resistant varieties. The necessity to analyze numerous samples from multiple replications of field grown materials prompted the development of a simple, rapid colorimetric determination of proline. The method detected proline in the 0.1 to 36.0 μmoles/g range of fresh weight leaf material.

Journal ArticleDOI
TL;DR: The compartmentalization of proline biosynthesis, accumulation and degradation in the cytosol, chloroplast and mitochondria is discussed and the role of prolines in cellular homeostasis, including redox balance and energy status, is described.

Journal ArticleDOI
TL;DR: Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species within normal ranges, thus preventing oxidative burst in plants.
Abstract: When exposed to stressful conditions, plants accumulate an array of metabolites, particularly amino acids. Amino acids have traditionally been considered as precursors to and constituents of proteins, and play an important role in plant metabolism and development. A large body of data suggests a positive correlation between proline accumulation and plant stress. Proline, an amino acid, plays a highly beneficial role in plants exposed to various stress conditions. Besides acting as an excellent osmolyte, proline plays three major roles during stress, i.e., as a metal chelator, an antioxidative defense molecule and a signaling molecule. Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species (ROS) within normal ranges, thus preventing oxidative burst ...

Journal ArticleDOI
TL;DR: Measurements on several dipeptides showed that proline peptide do not form ultraviolet-absorbing complexes with copper whereas prolyl peptides do form such complexes, which explains the finding that gelatin (which has a high proportion of proline and of hydroxyproline residues) is less reactive with copper than are the other proteins studied here.
