This study identifies redox-controlled dimerisation as a regulatory mechanism for ethylene biosynthesis enzyme ACO, revealing its role as a redox sensor in plant cells.

This study shows hydrogen sulfide modulates hypoxic responses in Arabidopsis by inhibiting plant cysteine oxidases through persulfidation, affecting gene activation and submergence tolerance.

The paper shows that H2O2 stabilizes ERFVII transcription factors in reoxygenation, leading to repression of hypoxia markers and activation of oxidative stress genes.
