GRANARIUS is aimed at studying the defense mechanisms of purple wheat against S. granarius by focusing on the overall potential biological, chemical, and genetic factors involved in the host finding and host acceptance by adult weevils. A set of durum and bread wheat Near-Isogenic Lines will be used that were derived from heterogeneous inbred families and contrasting for the color of the pericarp due to the diverse anthocyanin composition and content. The olfactory response of the granary weevil to VOCs emitted by purple and yellow grains will be evaluated. Also, the insect fitness on intact grains will be evaluated. We will use next generation technologies to search for molecular markers (SNPs and INDELs) associated with the key metabolite/component variants, and we will refer to both the durum and bread wheat reference genomes and to their respective transcriptomes to identify the target genes that significantly change their expression level within each NIL pair.
