Representative genes associated with FHB resistance identified in the 2Hb8 R NIL and 6Hb7 R NIL after F. graminearum infection. a Left panel, representative genes that had increased accumulation in the 2Hb8 R NIL compared to M69 at 48 hai. Right panel, representative genes that had increased accumulation in the 2Hb8 R NIL compared to M69 at 96 hai. ABCT, ABC transporter; GST, glutathione-S-transferase; CRK, cysteine-rich receptor-like kinase; LTP, lipid transfer protein; SLP, subtilisin-like protease; PMEI, pectin methylesterase inhibitor; HP, histidine-containing phosphotransfer protein; HK, histidine kinase; ARR, two-component response regulator. b Expression profiles of candidate genes in the 2Hb8 QTL region. EXO70H6, exocyst subunit exo70 family protein H6; HvS40, senescence regulator S40; VPS62, vacuolar protein sorting-associated protein 62; HHT, omega-hydroxypalmitate O-feruloyl transferase. c Representative genes that had increased accumulation in the 6Hb7 R NIL compared to Lacey at 48 h after F. graminearum inoculation. Note the later induction of genes in Lacey at 96 h after F. graminearum inoculation. PDR, pleiotropic drug resistance protein; UPS, ubiquitin proteasome system; IGPS, indole-3-glycerol phosphate synthase; AADC, aromatic amino acid decarboxylase; PRX, peroxidase
