Proline accumulation in plants: a review (2008, background): “This has been achieved by the genetic manipulation of osmolytes, transcriptions factors and more recently of the cytokinin hormone (Seki et al. 2007; Rivero et al. 2007).”
Improving water use efficiency in grapevines: potential physiological targets for biotechnological improvement. (2010, background): “In other cases, however, increased drought-tolerance can be associated with higher WUE, like in PSAG12-IPT transgenic tobacco (Rivero et al. 2007) or transgenic Arabidopsis expressing the bZIP transcription factor ABP9 (Zhang et al. 2008).”
Transgenic Plants for Abiotic Stress Resistance (2010, background): “An experiment to assess whether the transgenic plants could produce significant yields under water-limiting conditions determined that biomass and seed yield were not as affected in transgenic plants than in WT controls, although this result was not significant (Rivero et al. 2007).”
Analysis of Cytokinin Mutants and Regulation of Cytokinin Metabolic Genes Reveals Important Regulatory Roles of Cytokinins in Drought, Salt and Abscisic Acid Responses, and Abscisic Acid Biosynthesis[C][W] (2011, background): “Irreversible CK degradation is catalyzed by CKX, which selectively cleaves unsaturated isoprenoid side chains, resulting in the formation of adenine/adenosine and the corresponding side chain aldehyde (Sakakibara, 2006; Werner et al., 2006).”
Hormone balance and abiotic stress tolerance in crop plants. (2011, background): “The use of maturation-induced and stress-induced promoters (SARK, senescence associated receptor kinase [50]) to drive IPT expression in both dicots and monocots provided an alternative approach for the induction of IPT and the concomitant biosynthesis of CK, without the negative effects of constitu”
Comprehending crystalline β-carotene accumulation by comparing engineered cell models and the natural carotenoid-rich system of citrus (2011, neutral): “Despite the likely effects on phytohormone metabolism of transformation with a gene coding for isopentenyl transferase, and thus likely to decrease gs, this was not measured and substantial DR was attributed to altering leaf senescence, the process targeted, although decreased A suggests smaller gs ”
Chilling and Drought Stresses in Crop Plants: Implications, Cross Talk, and Potential Management Opportunities (2018, background): “Reguera et al. (2013) stated that drought tolerance in rice was concomitant with the accumulation of Cks. Drought tolerance induced by Cks has also been observed in tobacco (Rivero et al., 2007) and wheat (Shang, 2000).”
Advances in Host Plant and Rhizobium Genomics to Enhance Symbiotic Nitrogen Fixation in Grain Legumes (2015, background): “DLS has been found associated with enhanced adaptation to drought and increased biomass and grain yield under water stress (Ismail et al., 2000; Rivero et al., 2007; Gregersen et al., 2013).”
Postharvest Biology and Technology of Cut Flowers and Potted Plants (2012, background): “Rivero et al. (2007) demonstrated, in tobacco, that suppression of drought-induced leaf senescence in transgenic plants where IPT is driven by a drought-stress promoter resulted in outstanding drought tolerance of the transgenic plants, as well as minimal yield loss when the plants were watered…”
Genetic engineering for modern agriculture: challenges and perspectives. (2010, background): “Overcoming this genetic programming by expression of a gene mediating cytokinin biosynthesis under the control of a drought stress-inducible promoter was recently shown to result in a dramatic increase in plant productivity under drought stress conditions (104, 105).”
