An eQTL Analysis of Partial Resistance to Puccinia hordei in Barley
Figure 4
Overview of eQTL mapping results for genes previously mapped by SNP and TDM markers.
The x-axis shows the locations of eQTL associated with transcript abundance from the current experiment. The y-axis shows the location of genes mapped previously as SNPs (253 genes, [29]), TDMs (1066 genes, [31]) or both (63 genes). The 1256 previously mapped genes correspond to 1623 eQTL in the present study. eQTL corresponding to SNP- and TDM- mapped genes are displayed in blue and green respectively. eQTL with LOD score>10 and <10 are distinguished as circles or dots. Circles and dots on the diagonal represent correspondence between the locations observed in the current study with previous work [29], [31]. Circles or dots off the diagonal represent trans-eQTL. While all eQTL and their corresponding SNP-mapped genes were on the diagonal, 12 eQTL with LOD>10 (highlighted as numbered and red-filled green circles) when compared to TDM-mapped genes were located at distinctly different (>25cM away) positions.
