Use of Acyl-Homoserine Lactones Leads to Improved Growth of Ginseng Seedlings and Shifts in Soil Microbiome Structure

Panax ginseng is a well-known medicinal plant that achieves strong resistance against pathogens while growing in the wild. Due to high market demand for as health food source, cultivation prevalent South Korea. However, continuous monocropping creates problems like irregular growth or vulnerability crop diseases. Quorum sensing (QS) deals with intracellular communication of bacteria and plays role dynamic changes soil microbiome. Here, we investigated how acyl-homoserine lactone (AHL) signaling molecules QS (C8, C10, C12) improve induce shifts To assess effects, recorded root shoot seedlings checked microbiome during different time points (0, 2, 4, 8) after 8 weeks growth. We observed soils treated N-decanoyl-L-homoserine (C10) showed most pronounced effects. Very striking was C10 had lowest alpha diversity. Using Phylogenetic Investigation Communities by Reconstruction Unobserved States (PICRUSt2), number QS-related functional genes, highest count occurring untreated planted (W). Together known direct beneficial effects AHLs on development, mono-cropped trends community.
