#Evolution can innovate without inventing. Cell type families can retain ancient regulatory “vocabularies”, while individual cell types evolve by reshuffling how those motifs are combined. @natecoevo.nature.com New cell types from old regulatory words. We like this! doi.org/10.1038/s415...

Our review on #lichen research in the #omics era is out in @lichenologist.bsky.social! We discuss omics-driven progress and outline several areas and methods that we think especially promising for lichen biology, such as single-cell omics and epigenomics 🖥️ 🧪 🦠 🧫 #SymbioSky doi.org/10.1017/S002...
The infographic is divided into three columns.

Column 1: Sample Types.

At the top is a photo of a yellow Lichen Thallus. An arrow points down to a cross-section diagram showing green algal cells embedded in white fungal hyphae. Below this is Isolate Cultures, showing a petri dish and a test tube containing green liquid.

Column 2: Omics.

- Genomics: Assembly of D N A sequences into complete genomes, illustrated by blue horizontal bars and a double helix icon.

- Transcriptomics: Quantifying expression of genes, shown as small green segments aligning to a dark blue reference genome.

- Metabolomics: Analysis of metabolites, represented by a chemical molecular structure.

- Proteomics: Characterization of proteins, shown as a blue 3 D protein folding model.

- Epigenomics: Exploration of genome modifications, illustrated by blue circles representing histones wrapped in D N A with hexagonal tags.

Column 3: Advances and Opportunities.

- Evolution of lichenization: A phylogenetic tree paired with a horizontal bar chart.

- Gene regulation: A line graph showing chromatin accessibility and a heatmap for motif enrichment analysis. Below is a D N A sequence motif: C G C G A A A A A A.

- Symbiont interaction: A diagram comparing a bulk sample to isolated nuclei using single-cell transcriptomics, visualized with a stacked bar chart showing different cell population proportions.

Now, Starship transposons are often named after spacecrafts, so naturally we followed suit. After being up till 2 one night, I settled on Tangerine star buggy, which made a brief appearance in D. Adams’ The Restaurant at the End of the Universe. Given the color of Xanthoria, it was perfect. 5/6
It says: “Ford and Zaphod looked and passed on.
“And this baby,” said Ford, “the tangerine star buggy with the black sunbusters…”
Again, the star buggy was a small ship-a totally misnamed one in fact, because the one thing it couldn’t manage was interstellar distances. Basically it was a sporty planet hopper dolled up to something it wasn’t. Nice lines though. They passed on.”
