Triticeae Genomics and Genetics, 2025, Vol.16, No.2, 63-71 http://cropscipublisher.com/index.php/tgg 67 Figure 2 Genome wide association (GWAS) study in barley. (A) A Manhattan plot generated showing the seven barley chromosomes and the significant SNPs on the chromosome 4. The y-axis is the negative log10 transformed p-values of SNP from a genome-wide association analysis for Na+ plotted against the genetic distance in cM. (B) A zoom view of chromosome 4 with the bottom showing the candidate range for the gene HKT1;5 associated with low Na+ accumulation in barley using the Morex annotation genome. (C) A panel depicting the extent of linkage disequilibrium in this region based on r2. The r2 values are indicated using color intensity at the left bottom. A region of 1.5 Mb associated with HKT1;5 including other genes are indicated using two vertical dashed lines. Genes are represented in the middle panel (Adopted from Hazzouri et al., 2018)
