Genome-wide distribution of up- and down-regulated DEGs from WT, mus81 and msh4 along the Arabidopsis chromosomes. a. Density plot of up-regulated DEGs from WT, mus81 and msh4 along the Arabidopsis chromosomes with the distribution of expressed genes in WT as a control. b. Local enrichment analysis of up-regulated DEGs from mus81 and msh4. c. Density plot of down-regulated DEGs from WT, mus81 and msh4 along the Arabidopsis chromosomes with the distribution of expressed genes in WT as a control. d. Local enrichment analysis of down-regulated DEGs from mus81 and msh4. Chromosomes are partitioned into arm regions and centromeric regions (blue dashed lines) in (a, b, c and d). The horizontal black dashed lines in b and d indicate the P value = 0.05 from fisher test. Arrows in d show the two segments where there are significantly more down-regulated DEGs in msh4 than in WT.
