Transcriptomics, metabolomics, antioxidant enzymes activities and respiration rate analysis reveal the molecular responses of rice to Cd stress and/or elevated CO2 concentration

Purpose To explore the regulatory mechanism of rice to Cd stress and/or elevated CO 2 concentration. Methods The rice seedlings ( Oryza sativa L.) were exposed to two CO 2 concentrations (400 ± 20 μmol mol −1 , AC; 800 ± 20 μmol mol −1 , EC) and CdCl 2 concentrations (0 µmol L −1 , 150 µmol L −1 ) f...
