Abstract: (156 Views)
Low temperature stress is lead to accumulation of proteins, osmolytes and antioxidants that is involved in tolerance to stress conditions. This study was done to evaluate dehydrin, gamma-aminobutyric acid (GABA), endogenous proline and activities of antioxidant in Citrus reticulate under low temperature stress (1°C, -1°C and -3°C). The results of western blot showed proteins with the molecular weight of 30.19, 36.3 and 62.25 kDa were induced in C. reticulata under different temperatures. Also, level of endogenous proline, GABA and activities of antioxidant enzymes (SOD and APX) with decreasing of temperature were increased. Generally, in fruits under the temperature of -3°C, levels of antioxidants and protein accumulation increased.
