Five types of clustered DEGs involved in susceptibility to powdery mildew. a Susceptibility type A clusters of DEGs dramatically up-regulated in pad4–1 sid2–1 particularly at and after 6 dpi but no obvious change or only slightly up-regulated in Col-0. b Susceptibility type B clusters of DEGs up-regulated in both Col-0 and pad4–1 sid2–1 but the up-regulation in pad4–1sid2–1 are higher than that in Col-0. c Susceptibility type C clusters of DEGs up-regulated in both Col-0 and pad4–1 sid2–1 but dramatically up-regulated in pad4–1sid2–1 particularly at and after 6 dpi. d Susceptibility type D clusters of DEGs expressed higher in pad4–1sid2–1 than in Col-0 but down-regulated upon powdery mildew infection. e Susceptibility type E clusters of DEGs up-regulated in both Col-0 and pad4–1 sid2–1 at 1~6 dpi and then dropped back at 8~12 dpi with expression higher in pad4–1sid2–1 than in Col-0
