overexpression of gene ANR under control of the CaMV35S promoter via Agrobacterium tumefaciens strain EHA105 transformation, real-time quantitative PCR expression analysis, a number of genes encoding stress-responsivefunctional proteins are upregulated in the RrANR-overexpressing tobacco lines, phenotype, detailed overview. Rosa rugosa anthocyanidin reductase overexpression in Nicotiana tabacum enhances tobacco tolerance to abiotic stress through increased reactive oxygen species scavenging and modulation of abscisic acid signaling | Rosa rugosa |

metabolism | transcriptomic analysis of these transgenic Nicotiana tabacum lines indicate that RrANR overexpression induces global transcriptomic changes, including those involved in oxidation/reduction, hormone response and secondary metabolism. Genes related to abscisic acid biosynthesis and reactive oxygen species (ROS)-scavenging are upregulated in RrANR transgenic lines, and the effects are phenocopied by the direct treatment of tobacco plants with proanthocyanidins and abscisic acid. Overexpression of RrANR results in an increase in plant tolerance to oxidative stress via increased scavenging of ROS and modulation ofthe abscisic acid signaling pathway | Rosa rugosa |
physiological function | Anthocyanidin reductase (ANR) is a key enzyme involved in the biosynthesis of proanthocyanidins (PAs) and plays a role in the plant stress response , mechanism by which ANR confers stress tolerance in plants, overview. Rosa rugosa anthocyanidin reductase overexpression in Nicotiana tabacum enhances tobacco tolerance to abiotic stress through increased reactive oxygen species scavenging and modulation of abscisic acid signaling | Rosa rugosa |
