Enhanced proline accumulation and salt stress tolerance of transgenic indica rice by over-expressing P5CSF129A gene (2009, background): “genic wheat plants showed much higher (more than ten times) proline content than their wild-type counterparts under non-stress conditions (Sawahel and Hassan 2002). More recently, Yamchi et al. (2007) observed that there was 26 times more proline production in tobacco plants transformed with P5CS ge”
Genetic engineering of chickpea (Cicer arietinum L.) with the P5CSF129A gene for osmoregulation with implications on drought tolerance (2009, background): “Elevated proline levels due to the overexpression of Vigna P5CS in transgenic tobacco (Kavi Kishor et al. 1995); rice (Zhu et al. 1998), wheat (Sawahel and Hassan 2002) and potato (HmidaSayari et al. 2005) have been reported to confer enhanced tolerance to salt stress.”
Biotechnology and Drought Tolerance (2009, background): “aconitifolia P5CS gene into wheat resulted in improved salt tolerance, thus proving the osmoprotectant nature of proline in wheat (Sawahel and Hassan, 2002).”
Utilization of genes encoding osmoprotectants in transgenic plants for enhanced abiotic stress tolerance (2015, background): “Triticum aestivum P5CS Salt [33] of its expression was observed in plant growth, tuber morphology and yield [36].”
Desiccation of plant tissues post-Agrobacterium infection enhances T-DNA delivery and increases stable transformation efficiency in wheat (2003, methodology): “Effort was also made to develop an alternative method using different explants, yet only a few plants were generated (Amoah et al., 2001; Sawahel and Hassan, 2002).”
Improving Salinity Tolerance in Cereals (2013, background): “…in wild type Transgenic plants remained unaffected up to 200 mM and showed slight reduction at 250 mM, while respective wild plants died at 100 mM Sawahel and Hassan, 2002 Rice Vacuolar Na+/H+ antiporter AgNHX1 Atriplex gmelini Activity of these antiporters was 8-fold high Seedling survival…”
Proline Metabolism and Its Implications for Plant-Environment Interaction (2010, background): “…expressing P5CS in several of plant species and reporting increased resistance to soil drying/dehydration, salinity or cold (see for example: Zhu et al., 1998; Hong et al., 2000; Sawahel and Hassan, 2002; Su and Wu, 2004; Vendruscolo et al., 2007; Parvanova et al., 2004; Gleeson et al., 2005).”
Osmotic adjustment in transgenic citrus rootstock Carrizo citrange (Citrus sinensis Osb. x Poncirus trifoliata L. Raf.) overproducing proline (2004, result): “The introduction of p5cs gene in the citrus rootstock Carrizo citrange conferred higher accumulation of proline in the leaves, resulting in an effective increased tolerance to water deficit stress, confirming the results obtained by other authors using transgenic plants overproducing proline [28,40]”
Abiotic Stress in Plants and Metabolic Responses (2013, background): “Several studies have tested this by overexpressing genes for P5CS or P5C enzymes in different plant species, reporting the expected rise in proline levels and the associated resistance to dehydration, salinity, or freezing [46-53].”
Physiology and molecular biology of stress tolerance in plants (2006, background): “Transgenic wheat plants producing proline due to the expression of genes for proline biosynthesis, transferred from Vigna aconitifolia, exhibited improved tolerance to salinity (Sawahel and Hassan, 2002).”
Salinity Stress in Wheat: Effects, Mechanisms and Management Strategies (2021, background): “5 folds higher than the control (non-proline cultivar) to enhance salt tolerance in wheat [115].”
