Impacts of anthropogenic disturbances on antibiotic resistomes in biological soil crusts on the Qinghai-Tibetan Plateau.

Biological soil crusts (BSCs) are the main landscape on the Qinghai-Tibetan Plateau and an ecological indicator of human disturbance. Information about antibiotic resistomes in BSCs on the Qinghai-Tibetan Plateau can provide baseline for the risk assessment and management of resistomes and yet to be explored. This work investigated the profiles and geographic patterns of antibiotic resistomes in BSCs along the Lhasa River and their response to anthropogenic activities for the first time.

Toxic effects of chlorantraniliprole on zebrafish (Danio rerio) at different developmental stages under antibiotic pressure.

Pesticides and antibiotics have been frequently reported in the environment, but it remains unclear whether antibiotics affect the toxicity of pesticides to aquatic organisms. In this study, the acute, developmental and reproductive toxicity effects of the pesticide chlorantraniliprole on zebrafish at different developmental stages under pressure of ciprofloxacin and erythromycin at environmental concentration were explored. Chlorantraniliprole, ciprofloxacin, and erythromycin are all low toxic to zebrafish (LC > 100 mg/L), and environmental concentrations of antibiotics have no effect on the acute toxicity of chlorantraniliprole to zebrafish.

ZmGolS1 underlies natural variation of raffinose content and salt tolerance in maize.

Salt stress significantly inhibits crop growth and development, and mitigating this can enhance salt tolerance in various crops. Previous studies have shown that regulating saccharide biosynthesis is a key aspect of plant salt tolerance; however, the underlying molecular mechanisms remain largely unexplored. In this study, we demonstrate that overexpression of a salt-inducible galactinol synthase gene, ZmGolS1, alleviates salt-induced growth inhibition, likely by promoting raffinose synthesis.

Genome-wide identification and analysis of autophagy-related (ATG) genes in Lycium ruthenicum Murray reveals their crucial roles in salt stress tolerance.

The SpxA1-TenA toxin-antitoxin system regulates epigenetic variations of Streptococcus pneumoniae by targeting protein synthesis.

Human pathogen Streptococcus pneumoniae forms multiple epigenetically and phenotypically distinct intra-populations by invertase PsrA-driven inversions of DNA methyltransferase hsdS genes in the colony opacity-determinant (cod) locus. As manifested by phase switch between opaque and transparent colonies, different genome methylation patterns or epigenomes confer pathogenesis-associated traits, but it is unknown how the pathogen controls the hsdS inversion orientations. Here, we report our finding of the SpxA1-TenA toxin-antitoxin (TA) system that regulates the orientations of hsdS inversions, and thereby bacterial epigenome and associated traits (e.

Prodrug Self-Assemblies Based on Plant Volatile Aldehydes with Improved Stability and Antimicrobial Activity Against Plant Pathogens.

Plant volatile aldehydes (PVAs) such as cinnamaldehyde (Cin), citral (Cit), citronellal (Citr), and perillaldehyde (Per) have broad-spectrum antimicrobial activity and show great potential in agricultural sustainable production. However, most PVAs not only have very high volatility but also are easily degradable in environment, which seriously restricts their wide application. To address the inherent problems with PVAs, four prodrugs based on PVAs are fabricated by conjugating individually Cin, Cit, Citr, and Per to sodium bisulfite (Sod) through a simple addition reaction and subsequently self-assembled into nanoparticles (prodrug self-assemblies) in aqueous solutions.
