L-Proline accumulation in plants is a well-recognized physiological reaction to osmotic stress prompted by salinity, drought and other abiotic stresses. L-Proline plays several protective functions such as osmoprotectant, stabilizing cellular structures, enzymes, and scavenging reactive oxygen species (...
Proline accumulation in plants: not only stress. Plant Signal Behav 4:1016-1018 In addition to its role in protein synthesis and the plant cells' response to environmental stresses, circumstantial evidence suggest that proline may also... R Mattioli,P Costantino,M Trovato - 《Plant Signaling &...

The recent progresses in the research on proline will be described, focusing on plants and covering proline metabolism and signal transduction as well as the role of this imino acid in stress response. Furthermore, the recently described developmental role of proline in flowering and reproduction ...
known to accumulate in response to osmotic stress, proline apparently has a specific protective role in the adaptation of plant cells to water deprivation [72] and appears to be the preferred organic osmoticumin many plants. Nevertheless, controversy has arisen as to whether an increase in fre...
Pyroglutamic acid [(5-oxoproline (5-oxp)], a non-protein amino acid, can be converted to glutamate to regulate amino acid metabolism in plants. Its roles in plant adaptation to abiotic stresses, including heat stress, are not well understood. The objectives of this study were to determine...
Similarly, a decrease in the level of accumulated proline in the rehydrated plants is due to both down regulation of proline biosynthetic pathway enzymes and upregulation of proline degrading enzymes. But, the role of proline during plant development and the molecular basis of the effect of ...

, but in which proline metabolism may also play a regulatory role.A mechanism is proposed whereby the interconversions of proline and P5C in different cell types and the associated transfer of redox potential between tissues may constitute a form of metabolic signalling within higher plants. ...
It plays a role as an osmoprotectant under various stress conditions in plants [153], specifically under chilling stress [154]. It is commonly found in defined amounts in plants such as Arabidopsis, Triticum aestivum, Hordeum vulgare, and Nicotiana tabacum, whereas absent in plants such as ...
