Salt stress induced Gamma-aminobutyric acid (GABA) accumulation in maize plants. The germination of maize seeds was inhibited seriously by NaCl treatment, while exogenous GABA reduced the inhibition of NaCl on the seeds germination. Effects on SOD, POD and CAT activity of GABA were detected. 1-2 mmol/L GABA induced the increase of the activity of SOD, POD and CAT about 20%. Because of SOD, CAT and POD are important protective enzymes which can eliminate active oxygen, so GABA can alleviate the damage of salt stress through promoting the activity of the protective enzyme system.

In our previous study, three genes highly expressed in the roots of wheat were screened. To explore the effects of adverse stresses on the wheat root phenotype and the expression of , and , we measured the phenotypic parameters of the JM22 root system at the seedling stage after treatment with different concentrations of NaCl and PEG6000. Additionally, the relative expression levels of TaPSK3, TaPSK9, and TaPSK10 were analyzed via RT-qPCR within 72 h of treatment with 150 mM NaCl and 30% PEG6000.

WOX transcription factors (TFs) are plant specific transcription regulatory factors that have a momentous role in maintaining plant growth and development and responding to abiotic stress. In this study, a total of 13 PdbWOX genes were identified. qRT-PCR analyses showed that 13 PdbWOX genes were responsive to salt stress.

Myocardial dysfunction is a crucial determinant of the development of heart failure in salt-sensitive hypertension. Ferroptosis, a programmed iron-dependent cell death, has been increasingly recognised as an important contributor to the pathophysiology of various cardiovascular diseases. This study aims to investigate the role and underlying mechanism of ferroptosis in high-salt (HS)-induced myocardial damage.
