Excessive salt accumuln in soil is one of the most important abiotic stresses in agricultural environments. The Domain of Unknown Function 868 (DUF868) family, comprising 15 members in rice, has been identified in the protein family database. In this study, we cloned and functionally characterized , a member of the OsDUF868 family, to elucidate its role in rice response to salt stress. A series of experiments, including RT-qPCR, Agrobacterium-mediated transient transformation in tobacco for localization analysis, phenotypic characterization, physiological and biochemical index measurement, and leaf staining, were conducted to investigate the function of under salt stress. Transcriptional analysis revealed that exhibited the most significant response to low temperature and salt stress. Preliminary subcellular localization studies indicated that is localized in the cell membrane. Phenotypic Identification Experiments showed Overexpression lines of enhanced resistance to salt stress and increased survival rates, while knockout lines of were opposite. Physiological and biochemical assessments, along with leaf staining, demonstrated that overexpression of improved the activity against oxidative stress.under salt stress. Furthermore, overexpression of elevated the transcription levels of positively regulated salt stress-related genes. These findings suggest that overexpression of enhances rice tolerance to salt stress at the molecular level through a series of regulatory mechanisms. This study provides valuable insights into the functional roles of the DUF868 family in plant responses to abiotic stress.

Traumatic brain injury poses a major public health challenge with significant immediate and long-term effects. Repetitive head trauma is an ongoing area of research, and little is known about the response of cerebral blood vessels to such loading. This study investigated the mechanical response of cerebral arteries to repetitive overstretch, hypothesizing that repeated overstretch leads to cumulative damage.

In saline alkaline soils, microplastics inevitably form a combined stress with NaCl to limit crop growth, but the molecular mechanisms of their toxic effects remain vague and inadequate. We analyzed the molecular mechanisms underlying the response of maize seedlings to single or combined stresses of MPs and NaCl by means of combined metabolomic and transcriptomic analyses. MPs and NaCl single or combined stresses reduced plant fresh weight by 36.

Dehydration response element binding (DREB) transcription factors play multiple roles in plant growth, development and response to abiotic stress. However, their biological functions in response to salt and osmotic stress in vegetables of the Solanaceae family are largely unclear. Here, 49 CaDREB genes classified into six groups were identified in the pepper genome.

Background: Salt stress is considered to be one of the major abiotic stresses influencing rice growth and productivity. To improve rice crop productivity in saline soils, it is essential to choose a suitable variety for mitigating salt stress and gain a deep understanding of the underlying mechanisms. The current study explored the salt tolerance mechanism of wild rice 'HD96-1 (salt resistive)' and conventional rice 'IR29 (salt sensitive)' by evaluating morph-physiological, transcriptomic, and metabolomic approaches.

Agricultural waste (AW) presents significant environmental challenges if not effectively managed. Recycling AW as bio-organic fertilizers (BIOs) offers a sustainable solution, improving soil health, reducing dependence on chemical fertilizers, and stimulating crop growth. This study investigated the effectiveness of BIOs generated from AW composted with plant growth-promoting rhizobacteria (PGPR), including Enterobacter sp.
