Metabolome data of rice rhizosphere soil after applying NH1 strain under cadmium stress

Our study revealed that the application of Deinococcus sp. NH1 strain to rice seedlings under cadmium (Cd) stress effectively enhanced their Cd stress tolerance. To elucidate the mechanisms underlying the improved Cd resistance mediated by Deinococcus sp. NH1, we conducted a rigorously designed greenhouse pot experiment. The experiment comprised three treatment groups and one control group, as follows: Control group (CK): No Cd stress and Deinococcus sp. NH1 strain application; NH1 group (NH1): Application of Deinococcus sp. NH1 strain alone; Cd group (Cd): Application of CdCl₂ solution alone; Cd + NH1 group (Cd+NH1): Concurrent application of CdCl₂ solution and Deinococcus sp. NH1 strain.
Rhizosphere soil samples were collected after a specified period and analyzed using liquid chromatography-mass spectrometry (LC-MS)-based untargeted metabolomics. The metabolomic data were acquired in both positive ion mode (POS) and negative ion mode (NEG), resulting in two separate folders labeled "POS" and "NEG" for downstream analysis.
