Differential role of MAX2 and strigolactones in pathogen, ozone, and stomatal responses.

Strigolactones are a group of phytohormones that control developmental processes including shoot branching and various plant-environment interactions in plants. We previously showed that the strigolactone perception mutant has increased susceptibility to plant pathogenic bacteria. Here we show that both strigolactone biosynthesis ( and ) and perception mutants ( and ) are significantly more sensitive to DC3000.
