Fig. 11

The schematic representation of possible mechanism of melatonin mediated high temperature stress tolerance in tomato seedlings via the PAs and NO biosynthesis pathway. PAs: polyamines; ADC: arginine decarboxylase; ODC: ornithine decarboxylase; SPDS: spermidine synthase; SPMS: spermine synthase; SAMDC: s-adenosyl methionine decarboxylase; PAO: polyamine oxidase; NO: Nitric oxide; NR: nitrate reductase; NOS: nitric oxide synthase; ROS: reactive oxygen species; H2O2: hydrogen peroxide; O2•−: superoxide anion; RBOH: Respiratory burst oxidase; HSFA2: heat shock transcription factors A2; HSP90: heat shock protein 90
