Summary: The study demonstrated that Halimione portulacoides actively responded to higher concentrations of Ce, with the shoots showing decreased antioxidant enzyme activity at 1200 μg/L. High Ce concentrations led to a loss of turgor pressure and oxidative stress in the shoots, posing a threat to the sustainability of halophytes and estuarine marshes.

Summary: Salinity is a global problem caused by irrigation with salty water, excessive fertilization, or poor leaching capacity in soils. Biostimulants, like corn steep liquor (CSL), can enhance salt tolerance in plants by reducing the uptake and accumulation of toxic ions. This study found that CSL application improved photosynthetic efficiency and reduced the generation of reactive oxygen species, resulting in reduced phytotoxicity and increased growth of pepper plants under saline conditions.

Summary: This study evaluated salt tolerance in common vetch collections and investigated the underlying physiological mechanisms. The results showed that salt-tolerant collections of common vetch maintained lower levels of Na+ and higher levels of K+ and K+/Na+ ratio under salt stress compared to salt-sensitive ones. The expression of genes involved in Na+ and K+ transportation and redistribution was responsible for salt stress. Transcript levels of NHX7, HKT1, AKT2, and HAK17 were induced after salt stress, with higher levels in salt-tolerant collections. Proline accumulation and antioxidant defense system were also promoted in salt-tolerant collection. These findings suggest that salt tolerance in common vetch is associated with the maintenance of ion homeostasis, gene expression, proline accumulation, and antioxidant defense system.

Summary: Environmental pollution is a pressing global issue that needs priority attention. Traditional environmental remediation techniques have limitations in terms of effectiveness, energy consumption, and costs. Bioremediation techniques, especially phytoremediation, offer a promising alternative by using plants to remediate contaminated sites and prevent the dispersal of pollutants. This review proposes the use of plant biostimulants (PBs) to improve the efficiency of phytoremediation. Recent studies have shown that PBs, widely used in agriculture, can counteract the detrimental effects of pollutants on plants, particularly heavy metals. Different types of PBs, such as those derived from humic substances, protein and amino acid hydrolysate, inorganic salts, microbes, seaweed, plant extracts, and fungi, show promising prospects in the remediation of polluted environments.

Summary: This study found that a plant extract of an aquatic species, Lemna minor L. (LE), can improve the resistance of maize to copper toxicity. LE can reverse the effects of copper on maize photosynthetic activity, evapotranspiration, stomatal conductance, sub-stomatal CO2 concentration, and biomass. Furthermore, LE can reduce the content of hydrogen peroxide and malondialdehyde and increase the activity of antioxidant enzymes in maize. Untargeted metabolomic profiling revealed that LE can activate maize secondary metabolism and modulate plant stress-related hormones and non-enzymatic antioxidants. These findings have important implications for using LE as a biostimulant to enhance the resistance of maize to metal trace elements.
