Imidacloprid (IMI) stress positively correlates with the potential of coumarins to alleviate abiotic stress. However, little is known about the pathways and mechanisms by which coumarin reduces the IMI residue by regulating plant secondary metabolism and plant-microbe interactions. This study examined the impact of coumarin on the uptake, translocation, and metabolism of IMI in pepper plants by modulating the signal molecule levels and microbial communities in the rhizosphere and phyllosphere.

The susceptibility of bulk and exfoliated nanolayered arsenic to oxidation has been a significant obstacle limiting their widespread application and safe disposal. Here we report a controllable antimony-doped (Sb-doped) method via chemical vapor transport (CVT) with SnI as a transport agent to prepare the bulk arsenic. After 96 h of exposure to air, the oxygen content on the surface of Sb-doped arsenic with SnI is 67% lower compared to the undoped arsenic with SnI, and 89% lower than the control group (undoped arsenic without SnI).

Article Synopsis
  • Common arterial grafts for coronary artery bypass grafting include the internal thoracic artery (ITA), radial artery (RA), and right gastroepiploic artery (RGA), with the ITA showing the best clinical results.
  • An analysis of the single-cell transcriptomes of these grafts highlighted that the RA has more lipid-handling endothelial cells and that RGA smooth muscle cells are more prone to spasms; potassium channel openers could help alleviate this issue.
  • High expression of GDF10 and CREB5 in fibroblasts from the RA and RGA, along with significant signaling in macrophages from the RA, indicates potential strategies to enhance the performance and durability of arterial grafts by targeting these pathways.
