a Plot summarising all trait-associated regions identified by k-mer-based GWAS. Regions positively associated with traits are plotted above their respective chromosomes, while negatively associated regions are plotted below. For grain colour, positive and negative associations indicate brown and white, respectively. b A region significantly associated with panicle morphology was detected on chromosome 3B. The arrangement of the 13 genes within this region is displayed below the plot. The candidate gene qSH1 is highlighted. c A region significantly associated with Kaempferol 3-O-rhamnoside-7-O-glucoside (KOROG) was detected on chromosome 7A. The arrangement of the 26 genes within this region is displayed below the plot. The candidate gene CYP93G1 is highlighted. In (b and c), k-mers are grouped according to their association level and genomic coordinates (10 kb bins) and coloured according to the direction of association; red for panicle laxness or low KOROG, blue for panicle compactness or high KOROG. Point size is proportional to the number of k-mers rounded upwards to the nearest 10.
