Pleased to share our new preprint on mitochondrial retrograde signalling. Using single-nucleus RNA-seq+ spatial transcriptomics, we map cell-type and leaf polarity patterning, showing mitochondrial inhibition shifts nuclei among primed transcriptional states rather than triggering a uniform program.

Plants monitor the integrity of their barrier by sensing gas diffusion - Nature A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social‬ @erc.europa.eu‬ 1/x 🧵 www.nature.com/articles/s41...

Abolishing ANAC017‐Mediated Mitochondria Retrograde Signalling Alleviates Ammonium Toxicity in  Arabidopsis thaliana Ammonium (NH4+), an important nitrogen source, often fails to stimulate plant growth as a sole nitrogen source, a phenomenon known as ammonium toxicity syndrome. NH4+ is believed to disrupt cellular ....

Our work shows that abolishing ANAC017 function alleviates ammonium toxicity by supporting better metabolic coordination between mitochondria and chloroplasts.

While the U.S. is slashing science budgets, Europe is doubling down with their choose Europe for science initiative. Hopefully, the freshly emboldened Albanese government will step up and back science with some bold investments. @edhusicmp.bsky.social #ScienceFunding #HorizonEurope #AusPol

A tube-based biosensor for DNA and RNA detection The sensor performs cheap, sensitive, and visual DNA/RNA detection based on target-triggered change of surface wettability.

Scientists in Beijing built a 10¢ test that detects Covid in under 1 minute—faster, cheaper & more sensitive than PCR or CRISPR. No machines, no enzymes, no labs. Just flip a test tube and read the result, similar to a pregnancy test but faster & more sensitive.

Single-cell transcriptomics reveal how root tissues adapt to soil stress Nature - Single-cell RNA sequencing and spatial transcriptomic approaches reveal major expression changes in outer root cell types when grown in soil versus gel conditions, and also uncover how...

I'm so very excited to see this out - a single cell and spatial transcriptomic analysis in the rice root reveals mechanisms by which roots can respond to different below-ground growth conditions - including compaction. Congratulations to everyone for persisting in difficult times. rdcu.be/ej8Ui

A nice issue thanks to all the contributors!

My PhD student has been waiting for her visa for over eight months. If it continues for another couple of months, she might lose her scholarship.

This👇 perhaps not surprising but very important study showing that we need to address the conscious/unconscious bias when policing (and everything else) in multicultural societies.

Congratulations Tonni!! What an enjoyable story to read.
