Abstract
Polyamines (PAs) and nitric oxide (NO) are crucial signalling molecules that exhibit a promising role in improving stress tolerance in plants, maintaining their growth and development. They act as protecting agents for plants through activation of stress adaptation strategies such as membrane stabilisation, acid neutralisation and suppression of ROS generation. NO interacts with PAs during several developmental processes and stress responses. External supplementation of PAs to plants is also reported to cause an increase in NO content. However, it is unclear whether PAs promote synthesis of NO by either as substrates, cofactors, or signals. Impact of NO on synthesis of PAs has been also reported in some studies, yet the exact governing mechanisms of the interrelation between NO and PAs is currently obscure. Understanding the crosstalk between PAs and NO during growth and stress condition in plants can aid in providing better tolerance to plants against stressful environment.
