• Proline accumulation in plants: a review (2008, background): “Recently Székely et al. (2008) provided first evidence about the specificity of cell type and subcellular localization patterns of P5CS1 and P5CS2 proteins in Arabidopsis.”
• Exogenous proline significantly affects the plant growth and nitrogen assimilation enzymes activities in rice (Oryza sativa) under salt stress (2016, methodology): “Szekely et al. (2008) reported that rapidly dividing and growing cells show high expression of AtP5CS2, a gene responsible for the synthesis of D1-pyrroline-5-carboxylate synthetase (P5CS) that involved in proline biosynthesis, indicating that active cells have a high demand for proline.”
• A R2R3-type MYB gene, OsMYB2, is involved in salt, cold, and dehydration tolerance in rice (2012, methodology): “In addition, proline can also function as a molecular chaperone to stabilize the structure of proteins as well as play a role in regulation of the antioxidant system (Hare et al., 1999; Szekely et al., 2008).”
• Drought-induced changes in development and function of grapevine (Vitis spp.) organs and in their hydraulic and non-hydraulic interactions at the whole-plant level: a physiological and molecular update (2010, background): “Of two family members included in the Arabidopsis genome, P5CS1 is induced by osmotic stress while P5CS2 is developmentally regulated and is required for embryo vitality (Székely et al. 2008).”
• Extreme climatic events: impacts of drought and high temperature on physiological processes in agronomically important plants (2014, background): “Usually one of the P5CS isoforms is osmo-regulated and the other is associated with developmentally governed processes (Hur et al., 2004; Székely et al., 2008; Pérez-Arellano et al., 2010).”
• Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “Transcriptional profiling analysis revealed a massive influence of salinity on proline metabolism, including induction of several key enzymes, such as pyrroline-5carboxylate synthetase (P5CS) (Székely et al., 2007).”
• Ornithine-δ-aminotransferase is essential for Arginine Catabolism but not for Proline Biosynthesis (2008, background): “In response to osmotic stress, P5CS1 becomes re-localised to plastids [14].”
• Exogenous proline induces soluble sugar accumulation and alleviates drought stress effects on photosystem II functioning of Arabidopsis thaliana leaves (2011, methodology): “One week before the DS A. thaliana plants were either sprayed (foliar application 4 times in total, day after day) with water or with 10 mM proline (Székely et al. 2008).”
• Proline Metabolism and Its Implications for Plant-Environment Interaction (2010, background): “Consistent with the upregulation of AtP5CS1, p5cs1 knockout mutants have greatly reduced proline levels during salt or low water potential stress (Szekely et al., 2008; Sharma and Verslues, 2010). p5cs1 mutants were also reported to have reduced growth and altered reactive oxygen levels, suggesting…”
• Utilization of genes encoding osmoprotectants in transgenic plants for enhanced abiotic stress tolerance (2015, background): “thaliana and other plant species, the P5CS, which is a rate-limiting factor in proline biosynthesis, is encoded by two genes [27,28], while P5CR is encoded by a single gene [29].”
• Reactive oxygen species homeostasis and signalling during drought and salinity stresses. (2010, background): “Pro synthesis from glutamate, previously documented in the cytosol, was recently shown to occur, at least in part, in the chloroplast (Szekely et al. 2008).”
