简介
- Many plants accumulate proline, a compatible osmolyte, in response to various environmental stresses such as water deficit and salinity. In some stress responses, plants generate hydrogen peroxide (H2O2) that mediates numerous physiological and biochemical processes. The aim was to study the relationship between stress‐induced proline accumulation and H2O2 production.
- Using pharmacological and reverse genetic approaches in Arabidopsis thaliana, we investigated the role of NADPH oxidases, Respiratory burst oxidase homologues (Rboh), in the induction of proline accumulation was investigated in response to stress induced by either 200 mM NaCl or 400 mM mannitol.
- Stress from NaCl or mannitol resulted in a transient increase in H2O2 content accompanied by accumulation of proline. Dimethylthiourea, a scavenger of H2O2, and diphenylene iodonium (DPI), an inhibitor of H2O2 production by …
