The horizontal P-value dashed line represents the significance threshold. Figure 6. Ontology analysis of candidate genes. (A) Several functional categories were over represented especially those related to lipid binding, nuclease/hydrolase activity and transport. (B) Cellular compartments such as the membrane and cell wall showed a disproportionally high number of candidate genes. Figure 7. Correlation between GWAS and QTL studies. The adapted QTL cartographer shows the 12 rice chromosomes and indicates where the main association signals from this study are localised (red arrowheads on the left hand side). On the other side of each chromosome are major QTLs identified from multiple studies (see legend) where rice was exposed to saline conditions.
