Allelopathy and Exotic Plant Invasion: From Molecules and Genes to Species Interactions

Harsh P. Bais,1 Ramarao Vepachedu,1 Simon Gilroy,2 Ragan M. Callaway,3 Jorge M. Vivanco1*

Abstract: Here we present evidence that Centaurea maculosa (spotted knapweed), an invasive species in the western United States, displaces native plant species by exuding the phytotoxin (–)-catechin from its roots. Our results show inhibition of native species' growth and germination in field soils at natural concentrations of (–)-catechin. In susceptible species such as Arabidopsis thaliana, the allelochemical triggers a wave of reactive oxygen species (ROS) initiated at the root meristem, which leads to a Ca2+ signaling cascade triggering genome-wide changes in gene expression and, ultimately, death of the root system. Our results support a "novel weapons hypothesis" for invasive success.
