Transcriptomic Profiling Provides Molecular Insights Into Hydrogen Peroxide-Enhanced Arabidopsis Growth and Its Salt Tolerance.

ABSTRACT: Salt stress is an important environmental factor limiting plant growth and crop production. Plant adaptation to salt stress can be improved by chemical pretreatment. This study aims to identify whether hydrogen peroxide (H₂O₂) pretreatment of seedlings affects the stress tolerance of Arabidopsis thaliana seedlings. The results show that pretreatment with H₂O₂ at appropriate concentrations enhances the salt tolerance ability of Arabidopsis seedlings, as revealed by lower Na⁺ levels, greater K⁺ levels, and improved K⁺/Na⁺ ratios in leaves. Furthermore, H₂O₂ pretreatment improves the membrane properties by reducing the relative membrane permeability (RMP) and malonaldehyde (MDA
