Summary: The structure and function of barley beta-glucan were changed after fermentation with L. plantarum DY-1. The antioxidant activities of fermented and unfermented beta-glucan were evaluated using C. elegans, and their signature pathways were analyzed through transcriptomic and metabolomic profiling. The results showed that the two samples had different effects on oxidative stress and related pathways.

Summary: This study reveals the increased salt tolerance mechanism of heterografted chrysanthemums by using Artemisia annua as rootstock. The roots of heterografted chrysanthemums enrich Na+ under high salt stress, reducing Na+ toxicity in the scion. They also alleviate high Na+ stress through enhanced enzyme activity, downregulation of gene expression related to reactive oxygen species accumulation, accumulation of soluble sugars and proline, and upregulation of gene expression related to heat shock proteins. The leaves of heterografted chrysanthemums respond to low Na+ stress by increasing enzyme activity and soluble sugar and proline contents. Self-grafted and self-rooted plants, on the other hand, cannot integrate these responses to salt stress and exhibit a salt-sensitive phenotype.

Summary: Water shortages pose a significant threat to global food security and crop production, making it crucial to enhance crop tolerance to water stress. This study investigates the potential role of 0.1 mg L-1 24-epibrassinolide (EBL) and/or 25 mg L-1 spermine (Spm) in improving maize's tolerance to water-deficit conditions. The results show that EBL, alone or in combination with Spm, plays a major role in enhancing maize drought tolerance by regulating gene expression and increasing antioxidant defense enzymes. Furthermore, these treatments alleviate growth inhibition and oxidative stress, thus mitigating the negative effects of drought. Overall, this research highlights the significance of using EBL, either individually or in combination with Spm, to alleviate water stress in agriculture.

Summary: This study evaluated the effectiveness of potassium iodide (KI) in mitigating water deficits and improving fruit quality in tomatoes. The results showed that a concentration of 100 μM of KI increased the yield of tomatoes under a water deficit condition, and also improved antioxidant activity and photosynthetic efficiency, while reducing malondialdehyde levels. Additionally, this concentration of KI promoted better fruit quality through increased antioxidant capacity and a decline in the maturation index.

Summary: In this study, the use of selenium nanoparticles (SeNPs) as seed priming agents for enhancing drought tolerance in tomatoes was investigated. Four different SeNPs priming regimes were tested at different concentrations, along with a control treatment. The results showed that seed priming with 75 ppm SeNPs improved tomato crop performance under drought stress. The treatment reduced hydrogen peroxide and malondialdehyde levels, while increasing the functions of superoxide dismutase and catalase. Additionally, it increased the content of various beneficial compounds in tomatoes and upregulated the functions of enzymes involved in antioxidant defense. Seed priming with SeNPs is a promising strategy for sustainable tomato production in arid areas.

Summary: Treating soybean seeds with NAA can enhance their tolerance to drought stress, leading to increased germination and seedling establishment. The treatment reduces oxidative damage in seeds, enhances antioxidant capacity, improves TAG hydrolysis to sucrose in cotyledons, and strengthens sucrose transport from cotyledons to embryonic axes, promoting axis growth. This results in significantly higher germination percentage and seedling establishment percentage.

Summary: S100A9 plays a crucial role in the inflammatory response and contributes to aging-related pathologies and endothelial dysfunction. The deficiency of S100A9 alleviates vascular senescence, improves insulin resistance, reduces oxidative stress and inflammation in aged mice. The study suggests that targeting the S100A9/TLR4 signaling pathway may be a potential therapeutic strategy to prevent age-related cardiovascular diseases.

Summary: In this study, a previously unknown DUF1639 family protein, OsDUF1639.1, was identified to interact with SAPK10 and positively regulate ABA responses in rice. The phosphorylation of OsDUF1639.1 at Thr-80 by SAPK10 was found to be crucial for ABA-induced antioxidant defense.

Summary: The study showed that foliar application of MWCNT at concentrations up to 250 mg L-1 can alleviate Pb and Cd-induced toxicity and enhance the phytoremediation properties of pot marigold plants. However, higher concentrations of MWCNTs at 500 and 1000 mg L-1 exacerbated oxidative damage and reduced the accumulation of Pb and Cd in pot marigold seedlings. The research highlights the potential of MWCNTs to assist in phytoremediation of heavy metal polluted soils but also raises concerns about the toxic effects of high concentrations on plant physiology.

Summary: This experiment aimed to understand the protective impact of exogenous putrescine (Put) on Thymus daenensis plants under drought stress. Drought stress decreased growth attributes and photosynthetic pigments, while increasing oxidative stress indicators like malondialdehyde (MDA) and hydrogen peroxide (H2O2) in T. daenensis plants. Put treatment improved growth and regulated adaptive mechanisms, alleviating drought-triggered oxidative stress by reducing H2O2 and lipid peroxidation. Put treatment also enhanced the antioxidant system through induction of enzyme activities and non-enzymatic antioxidants.

Summary: The contribution of hydrogen sulphide (H2S) to salicylic acid (SA) induced lead (Pb) stress tolerance modulated by the ascorbate-glutathione (AsA-GSH) cycle was examined in pepper (Capsicum annuum L.) plants. Results showed that supplements of SA improved growth parameters, biomass, leaf water status, and AsA-GSH cycle-related enzyme activities, while increasing the H2S content. Additionally, the positive effect of SA was further enhanced when sodium hydrosulphide was added, but reversed by treatment with hypotaurine (HT).

Summary: This study found that the genetic mechanism of rice tolerance to high iron-associated stress in the field is complex, with favorable alleles mainly derived from the indica subpopulation. The study suggests that a strategy combining recurrent selection and genomic selection could enhance tolerance to this prevalent abiotic stress in West African rice varieties.

Summary: Iron toxicity is a major constraint to rice production, with varying tolerance levels in rice germplasm. Future breeding programs should be based on well-characterized molecular markers for iron toxicity tolerance traits, and tailored screening methods should be developed for individual mechanisms. Understanding and breaking down the complex tolerance response into its components will be crucial for successfully identifying such markers.
