Summary: Interactions between plants and soil microbes are important for plant growth and resistance. Through plant–soil‐feedbacks, growth of a plant is influenced by the previous plant that was growing in the same soil. We performed a plant–soil feedback study with 37 grass, forb and legume species, to condition the soil and then tested the effects of plant‐induced changes in soil microbiomes on the growth of the commercially important cut‐flower Chrysanthemum in presence and absence of a pathogen. We analysed the fungal and bacterial communities in these soils using next‐generation sequencing and examined their relationship with plant growth in inoculated soils with or without the root pathogen, Pythium ultimum. We show that a large part of the soil microbiome is plant species‐specific while a smaller part is conserved at the plant family level. We further identified clusters of plant species creating plant growth promoting microbiomes that suppress concomitantly plant pathogens. Especially soil inocula with higher relative abundances of arbuscular mycorrhizal fungi caused positive effects on the Chrysanthemum growth when exposed to the pathogen. We conclude that plants differ greatly in how they influence the soil microbiome and that plant growth and protection against pathogens is associated with a complex soil microbial community.

The article presents a study to investigate the possible relationship of xylazine anesthesia with amino acids neurotransmitter content in thalamus of rats. The involved 32 Wistar rats divided into different group and measured the contents by high liquid chromatography. The study found that the gamma aminobutyric acid (GABA) and glycine contents in the anesthesia group were increased compared with control group, while glutamate and aspartate contents were decreased.

The article presents research which investigates the effectiveness of the high performance liquid chromatography in detecting Qiangtongning in experimental dogs' blood plasma.
