After PA14 infection, gcs-1 expression was decreased by RNAi of pmk-1 in Xuebijing-treated nematodes, sod-3 expression was decreased by RNAi of daf-16 in Xuebijing-treated nematodes, egl-5 expression was decreased by RNAi of bar-1 in Xuebijing-treated nematodes, and F55G11.2 expression was decreased by RNAi of elt-2 in Xuebijing-treated nematodes (Supplementary Figure S4). Here, SOD3 is linked to infection.
