Article Synopsis
- Plant exposure to abiotic stresses leads to increased reactive oxygen species and triggers heightened antioxidant defense mechanisms.
- Previous studies indicated that external proline application can help alleviate oxidative stress by boosting antioxidant enzymes, but the impact of high endogenous proline levels on gene expression was not well understood.
- This study demonstrates that high levels of endogenous proline differentially regulate the transcription of antioxidant enzyme genes in transgenic plants, revealing proline's potential as a regulatory molecule that modifies stress-related gene expression, even under normal water conditions.
