Differential transcript regulation of target genes with and without significant TIGS effect on QR. Figure legend text. Transcript regulation in leaf epidermis under attack by Bgh (susceptible host interaction) or Bgt (resistant nonhost interaction) was analyzed from 6 to 74 h after inoculation by using an Agilent 44 K oligunucleotide array. Ninety-one candidate genes were significantly regulated (> two-fold regulation; FDR <0.05). Log2-transformed fold change data of Bgh- or Bgt-inoculated samples versus controls (Ctr) were subjected to hierarchical clustering with Euclidian distance and average linkage settings. Numbers to the right of the hierarchical clustering displays correspond to unigene numbers in HarvEST assembly #35. Numbered brackets correspond to clades of transcripts with similar regulation behavior. (A) Genes without significant TIGS effects. (B) Genes with significant (P <0.05, one-tailed) TIGS effects. Green dots, enhanced susceptibility; red dots, enhanced resistance.
