Function of proline in plants

WebThe amino acid L-proline has been the subject of intensive research during the past ten to fifteen years. This stems from the observations that it incorporates into peptide linkage thereby serving as a precursor to peptidyl-bound L-hydroxyproline, a constituent of “extensin,” and that it accumulates when some plants are exposed to diverse biological … WebFeb 1, 2010 · Multiple functions of proline in plants. Proline is used for protein synthesis, has protective functions as an osmolyte, contributes to the maintenance of the redox balance, can regulate development and is a component of metabolic signaling networks controlling mitochondrial functions, stress relief and development.

WebProline. Test Procedure: 1. By homogenizing 0.5 g of plant material in 10 ml of 3% aqueous sulphosalicyclic acid, the extract was made. 2. The homogenate is filtered through Whatman No. 2 filter paper. 3. 2 ml of filtrate is taken in a test tube and 2 ml of glacial acetic acid and 2 ml acid-ninhydrin are added in a sequence. 4. WebProline is an amino acid normally produced during protein production. In times of stress, plants over-produce this molecule which can be measured with whole leaf analysis. Elevated proline indicates stress responses have been initiated by the plant. The excess proline stimulates metabolic changes in the plant to cope with the stress.

Webplants use proline as a source of storage for carbon and nitrogen while Stewart and Lee (1974) reported that some halophytes use proline to adjust themselves osmotically. In turgid leaves, oxida- tion of proline occurs to maintain low levels of cellular proline, but in water stressed plants proline concentration increases because ... WebOct 18, 2024 · Among the amino acids involved in stress defense, proline is especially important because it accumulates in most plant species in response to different stresses and is believed to contribute to stress tolerance.
