is a bacterial pathogen capable of causing a wide variety of disease in humans. is unique in its ability to resist the host immune response, including the antibacterial compound known as nitric oxide (NO·). We used an RNA-sequencing approach to better understand the impact of NO· on in different environments. We discovered that inorganic phosphate transport is induced by the presence of NO·. Phosphate is important for the generation of energy from glucose, a carbon source favored by . We show that the absence of these phosphate transporters causes lowered energy levels in . We find that these phosphate transporters are essential for to grow in the presence of NO· and to cause infection. Our work here contributes significantly to our understanding of NO· resistance and provides a new context in which phosphate transporters are essential.

To improve the selenium (Se) uptake in grapes, the effects of arbuscular mycorrhizal fungi (AMF) on the Se accumulation in grapevines were studied under a soil Se concentration of 5 mg/kg, and the transcriptome and metabolome sequencing were used to elucidate the regulatory mechanism of AMF on Se accumulation. AMF initially decreased the biomass of grapevines, but later increased the biomass. Moreover, AMF enhanced the activities of Se metabolism enzymes (adenosine triphosphate sulfurylase, adenosine 5'-phosphosulfate reductase, serine acetyltransferase, and cysteine methyltransferase) and the Se concentration in grapevines.

Prenatal exposure to hazardous environmental pollutants is a critical global concern due to their confirmed presence in umbilical cord blood, indicating the ability of pollutants to cross the placental barrier and expose the fetus to harmful compounds. However, the transplacental transfer efficiencies (TTEs) of many pollutants remain underexplored. Herein, we developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantitatively analyze 91 environmental pollutants, including 13 bisphenols (BPs), 18 organophosphorus flame retardants (OPFRs), 7 brominated and other flame retardants (BFRs), 34 phthalates (PAEs), and 19 per- and polyfluoroalkyl substances (PFASs), in paired maternal and cord serums.
