Barley host response to F. graminearum infection. a Hierarchical clustering of FHB-responsive differentially expressed genes (DEGs) in 2Hb8 R NIL, 6Hb7 R NIL, M69 and Lacey at 48 and 96 hai. F48/M48 indicates comparison of F. graminearum- versus mock-inoculated samples. Red, induced; blue, repressed. b Categorization of FHB induced (red) or repressed (blue) genes in M69 at 48 and 96 hai. c A sunburst plot of enriched GO terms identified in DEGs in M69 at 48 and 96 hai. Size of individual slices represent statistical significance (−log₁₀FDR, larger size indicates higher significance). GO terms in blue boxes were enriched in repressed genes and GO terms in red boxed were enriched in induced genes. PAL, phenylalanine ammonia-lyase
