Despite its recognized importance, direct evidence linking MGO dynamics to plant growth under abiotic stress remains limited. To address this gap, we developed a benzoindole\u2010derived fluorescent probe\n                    <jats:bold>BH\u2010PDN<\/jats:bold>\n                    , which employs o\u2010phenylenediamine as the recognition group to enable sensitive detection of MGO through a specific ring\u2010closing reaction, accompanied by a pronounced red turn\u2010on fluorescence response (20.4\u2010fold enhancement).\n                    <jats:bold>BH\u2010PDN<\/jats:bold>\n                    exhibited exceptional detection capabilities, including a large Stokes shift (255\u00a0nm) and low detection limit (78\u00a0nM), allowing fluorescence visualization of exogenous and endogenous MGO\u2010associated changes in living cells, zebrafish, and\n                    <jats:italic>Arabidopsis thaliana<\/jats:italic>\n                    .
