Molecular mechanism of salicylic acid-induced abiotic stress tolerance in higher plants

We review recent progress toward characterizing the Salicylic acid -regulated genes and proteins, the SA signaling pathway, the connections and differences between SA-induced tolerances to biotic and abiotic stresses, and the interaction of SA with other plant hormones under conditions of abiotic stress

Scholarcy highlights

  • Salicylic acid, a key signaling molecule in higher plants, has been found to play a role in the response to a diverse range of phytopathogens and is essential for the establishment of both local and systemic-acquired resistance
  • Recent studies have indicated that SA plays an important role in abiotic stress-induced signaling, and studies on SA-modulated abiotic tolerance have mainly focused on the antioxidant capacity of plants by altering the activity of anti-oxidative enzymes
  • Little information is available about the molecular mechanisms of SA-induced abiotic stress tolerance
  • The future prospects related to molecular tolerance of SA in response to abiotic stresses are further summarized
  • Zhang Z, Zhang Q, Wu J, Zheng X, Zheng S, Sun X, Qiu Q, Lu T Gene knockout study reveals that cytosolic ascorbate peroxidase 2(OsAPX2) plays a critical role in growth and reproduction in rice under drought, salt and cold stresses
