When trees ruled the world

Around 300 million years ago, nature found a new plant strategy. #Lignin. It let plants grow taller by providing a solid structure that gave way to the first trees, scale trees, covering earth for 60M years.

For millions of years there was nothing that could break down the lignin so the trees didn't decompose, they simply fell and were gradually covered.

It's these trees, not dinosaurs, where our fossil fuels come from.

I wrote a little #lignin #plantbiology perspective article entirely in #rstats #Quarto a while back (leonardblaschek.github.io/asse) and had a blast. I ran into a couple of bugs along the way, but the quarto team was lightning fast in fixing them.

The only thing I'm still wrapping my head around is efficient co-writing with colleagues not using git. Any better ideas than rendering to .docx and manually copying track changes into the source file?

Researchers solve 2,000-year-old mystery of the destructive shipworm phys.org/news/2024-06-year-mys

First report of microbial #symbionts in the digestive system of #shipworms; wood boring mollusks sciencedirect.com/science/arti

"a population of symbiotic #microbes, living in an overlooked sub-organ of the gut called the #typhlosole, have the ability to secrete the #enzymes needed to digest #lignin—the toughest part of wood."

When plant parts #survive thousands of years. Dead plant parts filled with #lignin fulfill a variety of tasks as #wood in living #trees, but they also allow wood to survive for an impressively #longtime under suitable conditions.

Here, for example, wooden #coffins from #ancient #Egypt:
1) Coffin of a child, 22/23. Dynasty, 9th century BC.
2) Lid of the inner coffin of the priest Nespamai, 27th Dynasty, 500 BC.

phys.orgScientists engineer plant microbiome for the first time to protect crops against disease and cut use of pesticidesScientists have engineered the microbiome of plants for the first time, boosting the prevalence of 'good' bacteria that protect the plant from disease. The findings published in Nature Communications by researchers from the University of Southampton, China and Austria, could substantially reduce the need for environmentally destructive pesticides. The paper is titled "Microbiome homeostasis on rice leaves is regulated by a precursor molecule of lignin biosynthesis."

Transparentes #Holz 🤨

Btw: #Lignin ist ein unterschätzter Stoff. Eines der am häufigsten vorkommende Rohstoffe, wird aber aktuell meist nur verbrannt ("energetisch verwertet"...). Mitlerweile gibt es Bemühungen Lignin unter anderem in der #Biotechnologie als Nährmedium einzusetzen. Besser als Glukose, das bei der Herstellung #Pestizide erfordert...
