Plants produce hydroxycinnami c acid (HCA) defense com- pounds to combat pathogens, such as the bacterium Ral- stonia solanacearum . We showed that an HCA degradation pathway is genetically and functionally conserved across diverse R. solanacearum strains. Further, a feruloyl-CoA synthetase ( ? fcs ) mutant that canno t degrade HCA was less virulent on tomato plants. To understand the role of HCA ...
