Evolution of the PUF posttranscriptional regulons in plant and animals. (A) The occurrence of P4E in the nucleolar genes of plant and animals. (B) The occurrence of P3E in the nucleolar genes of plant and animals. (C) The occurrence of P3E in the mitochondrial genes of plant and animals. (D) The occurrence of P4E in the mitochondrial genes of plant and animals. P4E and P3E were detected at the 1,000-bp 3′UTR regions in each species. Green bars denote the percentage of genes with the motif in the studied organelle and blue bars denote the percentage of genes with the motif at the whole-genome level.
