It is widely distributed in the southern subtropical and tropical areas of China and has important ecological and economic value. The growth and metabolic processes of <i>A. odoratissima</i> are affected by drought stress, but the molecular mechanisms remain unknown. Therefore, this study investigated the physicochemical properties, gene expression, and metabolites of <i>A. odoratissima</i> seedlings under drought stress. The results show that, in leaves of <i>A. odoratissima</i> seedlings, drought stress reduced the moisture content, chlorophyll content, photosynthetic efficiency, superoxide dismutase (SOD) activity, and gibberellin (GA) and indoleacetic acid (IAA) contents while increasingPlants (Basel, Switzerland)Transcriptome and Metabolome Analyses Reveal the Molecular Mechanisms of &lt;i&gt;Albizia odoratissima&lt;/i&gt;'s Response to Drought Stress.PMC11478484AB21220026AB240100090Yin GLiu ZWei SWen SOu HGao FWang ZfalseTranscriptome and Metabolome Analyses Reveal the Molecular Mechanisms of &lt;i&gt;Albizia odoratissima&lt;/i&gt;'s Response to Drought Stress.<i>Albizia odoratissima</i> is a deciduous tree species belonging to the family <i>Leguminosae</i>.
