Submitter Supplied Information

Wall associated kinases (WAKs) have recently been identified as major components of fungal and bacterial disease resistance in several cereal crop species. However, the molecular mechanisms of WAK-mediated resistance remain largely unknown. Here, we applied the RNAseq approach to investigate the function of the maize gene ZmWAK-RLK1 (Htn1) that confers quantitative resistance to northern corn leaf blight (NCLB) caused by the hemibiotrophic fungal pathogen Exserohilum turcicum. A transcriptome analysis of near-isogenic lines (NILs) differing for ZmWAK-RLK1 revealed that several genes involved in the biosynthesis of the secondary metabolites benzoxazinoids (BXDs) were differentially expressed in the presence of ZmWAK-RLK1. Overall design: Two maize genotypes (w22, B37) containing or not the gene Htn1, were infected or not with E .turcium. Three biological replicates of each interaction were collected. Infected samples were taken at four different time points (0h, 9h, 3d and 10d after inocluation). In total 48 samples
