Identified metabolic pathways and genes required for growth of a necrotrophic pathogen in planta – the uridine monophosphate, purine and leucine, cysteine, and lysine biosynthetic pathways are essential for bacterial survival in the plant; RsmC and GcpA are important for regulating the infection process; and glycosylation of flagellin confers fitness during plant infection. Here, C11orf98 is linked to infection.
