Transcription factor bHLH25 plays a dual role in #plant defense.
🛡️Oxidized, it boosts #lignin production to strengthen #cell walls against #pathogens.
⚔️Non-oxidized, it activates #phytoalexins to inhibit pathogen growth.
🤝Together, these functions may help us create disease-resistant #crops without yield loss.

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 (https://leonardblaschek.github.io/assets/2024_JAFC/index.html) 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?

#Biosynthesis of #cellulose, #lignin, and #hemicelluloses in #plants is regulated by a transcriptional regulatory network featuring orthologous shared TFs of #poplar and #Arabidopsis.

"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."

Revolutionizing Renewable Energy: Scientists Develop New Low-Cost #Battery With Over 8000 Uses https://scitechdaily.com/revolutionizing-renewable-energy-scientists-develop-new-low-cost-battery-with-over-8000-uses/ “Researchers at Linköping University in Sweden have developed a battery constructed from #zinc and #lignin that can be #recharged over 8,000 times. This innovation aims to offer an affordable and eco-friendly battery alternative, especially for regions with limited electricity access. The findings are detailed in the journal Energy & Environmental Materials.”

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.
