Interactions between metal cations, notably Cu(II), and humic substances (HS) affect their mobility, bioavailability, and toxicity. This necessitates a molecular-level determination of the nature of HS functional groups binding Cu(II) (Cu-HS) and effects of pH on them. This study investigates the pH effects on the spectroscopic and structural properties of the complexes of Cu(II) with HS and representative model compounds using differential absorbance spectroscopy (DAS), examination of the properties of the d-d transition band characteristic for Cu(II) ions, and quantum chemical (QC) calculations.

Due to shallow root systems, potato is a particularly drought-sensitive crop. To counteract these limitations, the application of plant growth-promoting microorganisms (PGPMs) is discussed as a strategy to improve nutrient acquisition and biotic and abiotic stress resilience. However, initial root colonization by PGPMs, in particular, can be affected by stress factors that negatively impact root growth and activity or the survival of PGPMs in the rhizosphere.

Article Synopsis
  • * Histological analysis indicated that hypertensive rats had milder symptoms, with less edema and hemorrhage, plus localized lesions with better-preserved epithelial tissue compared to their normotensive counterparts.
  • * The research suggests that differences in vascular responses and coagulation in hypertensive rats may contribute to this protective effect, highlighting the need for further studies to understand the mechanisms and potential treatments for gastric injury in those with hypertension.

The accumulation of the emerging pollutant salicylic acid (SA) in the environment has gained much attention. In this study, overexpression of the non-ribosomal peptide synthase (NRPS) gene, PtNRPS1 in the marine diatom Phaeodactylum tricornutum (PtNRPS1-OE) increased resistance to SA pollutants. It was assumed that the enhanced tolerance was due to the high binding affinity between recombinant PtNRPS1 (rNRPS1) and SA pollutants.

This review addresses plant interactions with HMs, emphasizing defence mechanisms and the role of chelating agents, antioxidants and various elicitor molecules in mitigating metal toxicity in plants. To combat soil contamination with HMs, chelate assisted phytoextraction using application of natural or synthetic aminopolycarboxylic acids is an effective strategy. Plants also employ diverse signaling pathways, including hormones, calcium, reactive oxygen species, nitric oxide, and Mitogen-Activated Protein Kinases influencing gene expression and defence mechanisms to counter HM stress.
