Physiological and proteomic analysis of halophyte <i>Halogeton glomeratus</i> in response to Ni²⁺ stress.

ABSTRACT: Halogeton glomeratus (H. glomeratus) is a halophyte that can remediate heavy metals in soil. However, knowledge regarding the mechanisms of Ni remediation in H. glomeratus is limited. In this study, the physiological and molecular mechanisms of H. glomeratus seedlings exposed to different Ni²⁺ conditions were investigated. The results revealed that H. glomeratus growth was significantly inhibited when the Ni²⁺ concentration was higher than 1.5 mM, but the seedlings did not experience any seedling death and physiological characteristics showed no significant decrease. The accumulation of Ni²⁺ in H. glomeratus was found in Ni²⁺-treated seedling roots, stems and leaves. The size of water-storage tissue, the
