Resistance of Fritillaria imperialis to freezing stress through gene expression, osmotic adjustment and antioxidants
Original language description
Plant survival in response to freezing stress depends on the efficient activation of tolerance mechanisms. Fritillaria imperialis exposure to freezing stress enhanced signalling molecules Ca2+ and H2O2 along with overexpression of Ca2+ signalling proteins -Ca2+ dependent protein kinases, CPK-, followed by upregulation of NHX1 -Na+/H+ antiporter-, LEA -late embryogenesis abundant proteins- and P5CS -1-pyrroline-5-carboxylate synthetase-. Overexpression of OsCNGC6 was responsible for high accumulation Ca2+, Na+ and K+. The NHX1 gene product transported Na+ to vacuoles and increased cytosolic K+ content to re-establish ionic homeostasis under stress conditions. The reduced water potential of leaves was due to high accumulation of osmolytes and ions. No changes were observed in relative water content of leaves, which might be correlated with overexpression of the LEA gene, which protects against dehydration. High accumulation of H2O2 under freezing stress was responsible for activation of antioxidant sys
