Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System
Advanced Science, Volume 13, Issue 32, 9 June 2026.Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches
Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.Abstract While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use. We evaluated the potential of non‐radioisotopic approaches to estimating net Pmin by difference before and after aerobic incubation, analogous ...
