Summary: This study aimed to investigate the physiological and cellular mechanisms of Sesuvium portulacastrum under heavy metal stress. The findings suggest that superoxide dismutase (SOD) is the dominant antioxidant enzyme activity during low cadmium toxicity, while peroxidase (POD) is the dominant enzyme activity during higher cadmium toxicity. In addition, cadmium stress affects the chlorophyll content and cell structure of Sesuvium portulacastrum.

Summary: Sesuvium portulacastrum is a halophyte that can naturally grow in saline environments. It can tolerate high concentrations of NaCl without significant growth reduction. After salt treatment, it accumulates beneficial substances and restores transcriptional activity. The overexpression of gene SpRAB18 in soybean increases biomass and maintains growth benefits even under high salt conditions. Additionally, the development of an open-access transcriptome database SesuviumKB provides a platform for studying the functional genes of S. portulacastrum and engineering salt tolerance in crops.

Summary: This study investigates the impact of aging processes on the performance of biochar in adsorbing Cd(II) as well as the distribution of Cd(II) speciation. The results show that aging significantly inhibits the adsorption performance of biochar for Cd(II), but has little influence on the speciation distribution. Among the three pyrolysis temperatures, biochar prepared at 500 degrees C shows the most promising immobilization for Cd(II).

Summary: The growth and development of plants are influenced by salinity. The SOS pathway, consisting of SOS3, SOS2, and SOS1, plays a crucial role in plant response to salt stress. In this study, a new CIPK gene (SpCIPK8) and a CBL gene (SpCBL10) were identified from the halophyte S. portulacastrum. The expression of SpCIPK8 and SpCBL10 was induced by salt stress in the roots of S. portulacastrum. Yeast two-hybrid assays revealed an interaction between SpCBL10 and SpCIPK8. Co-expression of SpSOS1, SpCIPK8, and SpCBL10 in yeast enhanced salt tolerance by excluding Na+ from the cells and increasing K+ accumulation. The findings suggest that the SpCBL10/SpCIPK8 complex regulates the cell membrane Na+/H+ antiporter SpSOS1 and provide candidate genes for improving plant salt tolerance.

Summary: This study explored the difference in cadmium accumulation ability among different genotypes of Solanum nigrum and revealed the underlying mechanism. The results showed that cadmium was more abundant in cell sap and cell wall fraction, and the content of organic acids in S. nigrum leaves followed the order citric acid > tartaric acid > acetic acid > malic acid > oxalic acid. Non-destructive micrometry revealed that the net cadmium fluxes first increased and then decreased with increasing cadmium concentration, and S. nigrum genotype (HZ) had the strongest net cadmium fluxes.

Summary: High bicarbonate concentrations in calcareous soils with high pH can impact crop performance, with iron deficiency being a key concern. In this study, comparative transcriptomic analysis of Arabidopsis thaliana demes revealed that carbonate-tolerant plants exhibit better growth and nutrient homeostasis under alkaline conditions, with different gene expression patterns in response to bicarbonate stress compared to sensitive plants. This suggests that carbonate-tolerant plants have a more efficient response to bicarbonate stress, with a focus on stress perception, signal transduction, sulfur acquisition, and cell cycle regulation before iron homeostasis mechanisms are induced.

Summary: Alkaline salinity constrains crop yield. Arabidopsis thaliana shows local adaptation to saline-siliceous and non-saline carbonate soils, but no natural population is found on saline-alkaline soils. This study suggests that tolerance to saline-siliceous soils may not confer tolerance to alkaline salinity.

Summary: By evaluating the growth condition variation of 270 natural accessions of Arabidopsis thaliana on a natural saline-carbonated soil, significant natural variation in leaf sodium and iron concentrations was discovered. The diversity in leaf sodium concentration was associated with allelic variation in the NINJA and YUC8 genes, while leaf iron concentration diversity was associated with allelic variation in the ALA3 gene. The allelic variation in these genes leads to changes in mRNA expression and correlates with plant differential growth performance under alkaline salinity treatment.

Summary: The increased availability of toxic Al3+ is the main limitation for plant growth on acid soils. However, some plants adapted to acid soils can tolerate and accumulate high levels of Al in their aerial parts. Previous studies have focused mostly on acid soils in the northern and southern hemispheres, while acid soils outside of these regions have been neglected. This study investigated the acid soils of tea plantations in Northern Iran and found that several species can accumulate high amounts of Al and Fe, making them suitable for soil rehabilitation.

Summary: The effect of sodium chloride (NaCl) on cadmium (Cd) tolerance, uptake, translocation, and compartmentation in barley was studied. NaCl did not significantly affect plant development and biomass production, but Cd alone reduced plant development rate and biomass production. NaCl addition accentuated the Cd effect on plant growth. NaCl limited Cd accumulation in the roots and shoots by reducing Cd-absorption efficiency and translocation. However, NaCl increased Cd toxicity and limited plant yield.
