Abstract excerpt
Strigolactones (SLs) are carotenoid-derived hormones that regulate plant development and abiotic stress responses, but their role in regulating plant-microbe interactions remains unclear. Here, we show that Arabidopsis thaliana loss-of-function mutants of two SL biosynthetic genes, MORE AXILLARY GROWTH 3 (MAX3) and MAX4, exhibit opposite responses to soil-borne pathogen Ralstonia solanacearum, with max3 mutants...
