A row of houses and a mountain can be seen behind rafts for cultivation of laver lined up in parallel. It just looks like a visualization of RNA-seq data mapped to a reference genome in order to see the depth of coverages (mountain) of reads (rafts) around a certain exon (row of houses) . We thank Dr. Fumiki Katsuoka (Tohoku Medical Megabank Organization, Tohoku University) for providing such a splendid idea for us.
At first glance, it might seem to be a Japanese rock garden (karesansui) with wavy lines in the sand (samon); however, it is actually an electron microscopic photograph of Drosophila midgut epithelium taken with the freeze-fracture method. The lines that look like samon are smooth septate junctions, which are a kind of occluding junction seen in invertebrates. We thank Prof. Mikio Furuse and Ms. Kyoko Furuse (National Institute for Physiological Sciences) for providing the data and sharing the idea of karesansui.
