Multidrug Pump Inhibitors Uncover Remarkable Activity of Plant Antimicrobials
TLDR
The results suggest that plants might have developed means of delivering their antimicrobials into bacterial cells and suggest that plant antimicroBials might be developed into effective, broad-spectrum antibiotics in combination with inhibitors of MDRs.

Synergy in a medicinal plant: antimicrobial action of berberine potentiated by 5'-methoxyhydnocarpin, a multidrug pump inhibitor.
TLDR
The level of accumulation of berberine in the cells was increased strongly in the presence of 5'-MHC, indicating that this plant compound effectively disabled the bacterial resistance mechanism against the berberines antimicrobial.

Enantiomeric-Dependent Phytotoxic and Antimicrobial Activity of (±)-Catechin. A Rhizosecreted Racemic Mixture from Spotted Knapweed1
TLDR
It is found that (−)-catechin is a root-secreted phytotoxin that undoubtedly contributes to spotted knapweed's invasive behavior in the wild.

Biogeographical variation in community response to root allelochemistry: novel weapons and exotic invasion
TLDR
Eurasian plants and soil microbes may have evolved natural resistance to 8-hydroxyquinoline while North American plants have not, suggesting a remarkable potential for evolutionary compatibility and homeostasis among plants within natural communities and a mechanism by which exotic weeds destroy these communities.

Metabolic profiling of root exudates of Arabidopsis thaliana.
TLDR
An in vitro system implementing root-specific elicitation over a 48-day time course was developed and several compounds exhibited a wide range of antimicrobial activity against both soil-borne bacteria and fungi at the concentration detected in the root exudates.
