From: Plant organ evolution revealed by phylotranscriptomics in Arabidopsis thaliana
Enrichment analysis of organ-specific sense-expressed genes in different phylostrata. RSF: genes with expression shared by Root, Seedling and Flower; S: Seedling-specific expressed genes; R: Root-specific expressed genes; F: Flower-specific expressed genes; Total: all the protein coding genes with an assigned phylostratum. Gray line: A log-odds of zero, which corresponds to the actual number of organ-specific genes in each phylostratum equaling the predicted number. Because there are zero S genes from phylostratum Arabidopsis, the log-odds value is undefined here. In plotting the figure, we conservatively adjusted the observed count to one and re-calculated the log-odds value. (*p-value < 0.05, **p-value< 0.01 and ***p-value < 0.001).
