Exogenous nitric oxide (NO) application reprograms soybean (Glycine max L.) to improved growth and flooding stress tolerance

The rapidly increasing human population and anthropogenic activities caused global climate change, which resulted in different environmental stresses. Among the various environmental stresses caused by climate change. Flooding stress is considered a major restrict factor of grain yield loss. Moreover, nitric oxide (NO) is a small bioactive molecule which has been reported to be actively involved in stress tolerance. However, the role of nitric oxide in flooding stress is not fully explored. Therefore, the current study was undertaken to investigate the role of nitric oxide in flooding stress mitigation, plant growth response, stress related endogenous abscisic acid modulation (ABA) and amino acids regulation.
