Nitric oxide regulation of temperature acclimation: a molecular genetic perspective

The current environmental situation is dominated by climate change, including heat and cold waves that trigger adverse conditions for plant growth and development. Identification of key signalling molecules during stress-related events can help in the development of strategies to mitigate detrimental effects and to improve plant tolerance. Among stress regulators, nitric oxide (NO) has emerged as a central gasotransmitter involved in the control of adaptive responses, acting to tailor plant growth and stress responses. Here, we outline the implications of this control by NO and highlight the genetic and molecular evidence for its role in enhancing tolerance and adaptation to heat and cold stress, which in turn has revealed possible new approaches for confronting future environmental challenges.

Automated summary

Climate change affects plant growth with heat and cold waves, but identification of key signaling molecules like nitric oxide can help mitigate adverse effects and improve plant tolerance. NO is a central gasotransmitter in stress responses, enhancing plant adaptation to heat and cold stress and suggesting new approaches for future environmental challenges.
