Fabulous film about @jenmcgaley.bsky.social's work in the @paszkowskilab.bsky.social. Jen has captured arbuscular mycorrhiza in motion for the first time. Find out more 👉https://tinyurl.com/yc2brzcu 🧪 @cambridgebiosci.bsky.social

What if one organism could copy itself and merge with others, weaving vast living networks? Meet the arbuscular mycorrhizal fungi 🦠 Cambridge researcher Dr Jennifer McGaley from @camplantsci has filmed these fungi in action for the very first time. Find out more 👉 https://bit.ly/4ghAynD

My postdoc preprint is now online @biorxiv-plants.bsky.social. We established HYDRA, a shoot regeneration assay in Arabidopsis without exogenous hormones, and show that photosynthesis-derived carbon drives regeneration via RBR1 pathway–mediated cell cycle activation. www.biorxiv.org/content/10.6...

Photosynthesis-derived carbon gates cell cycle activation to enable hormone-autonomous shoot regeneration

Shoot regeneration is a powerful model for cell fate reprogramming but how it occurs in nature remains poorly understood because studies in Arabidopsis thaliana conventionally rely on in vitro assays ...

The first fatty acid-binding structure in a “G-type lectin domain” among plant PRRs has been verified! A new LORE paper is out from Ranf lab at TUM in Germany and University of Fribourg in Switzerland and @antonelladipizio.bsky.social at TUM : doi.org/10.64898/202... Here are some cool highlights:

The plant immune receptor LORE binds agonistic and antagonistic 3-hydroxy fatty acid ligands via a dynamic loop in its G-type lectin domain

The Arabidopsis thaliana S-domain receptor kinase LORE senses bacterial medium-chain 3-hydroxy fatty acids (mc-3-OH-FAs) as microbe-associated molecular patterns to activate pattern-triggered immunity...

TIRs are key regulators of plant immunity, but the role of conserved TIR-only proteins has remained unclear. Here, we compare TIR-only proteins from Arabidopsis and barley and show that they share a conserved role in plant immunity. www.biorxiv.org/content/10.6...

Conserved TIR-only proteins drive transcriptional defense and basal immunity in dicot and monocot plants

Toll/interleukin-1/resistance (TIR) domain NADase enzymes signal in plant immunity by producing ribosylated nucleotide second messengers which activate EDS1 dimer-helper NLR pathways to restrict patho...

Excited to share that I will start my lab this summer as an ECL Unit Leader at RIKEN CSRS! We will study perception by cell-surface receptors across diverse plant species. I’ll be recruiting soon, so please reach out if you’re interested!

Making Connections...🖇️ Koh Aoki & Ayako Tsushima offer a compelling insight into interspecific secondary #plasmodesmata and their importance in establishing symplastic connections between #ParasiticPlants and their hosts #OpenAccess: doi.org/10.1093/pcp/... #PlantScience

Interspecific secondary plasmodesmata at the parasitic interface

Abstract. Obligate parasitic plants often establish symplastic connections with their hosts. This symplastic continuity is mediated by plasma membrane-line

Now out in Science Advances. Inceptin Receptor helps attract predatory wasps in two years of field experiments. Next steps: can we tune both receptor recognition and volatile blend traits in crops + companion plants?

Adam Steinbrenner@adsteinbrenner.bsky.social · last yr.

How do predatory wasps find their caterpillar prey? In our new preprint on Biorxiv we show that the host plant's immune system detects herbivory to sound the alarm. 🌱🐛 See thread from @nataliagupa.bsky.social -- a surprising role for a plant PRR in indirect defense against herbivores.

How do plants respond to wounding? Well it it's not too dissimilar to how they respond to heat. We found that plants utilize the HSFA1 transcription factors to rapidly induce wound-induced regeneration genes after injury. @keikosugimoto.bsky.social @deveylderlab.bsky.social @wigge.bsky.social

Wounding activates the HSFA1 transcription factors to promote cellular reprogramming in Arabidopsis

The HEAT SHOCK FACTOR A1 transcription factors rapidly accumulate in the nucleus after wounding and directly activate regenerative pathways in plants.

Cell-surface receptors play key roles across many biological processes. In plants, these receptor families have undergone remarkable expansion. Here, we systematically review these receptors in @theplantjournal.bsky.social Happy to see this out! onlinelibrary.wiley.com/doi/10.1111/...

Plant cell surface receptors

Plant cell surface receptors have evolved to perceive peptides, proteins, glycans, lipids, and small molecules through diverse ectodomains, integrating these inputs into distinct physiological output....

Out in @science.org this week, two fungal enzymes synthesise DHHA, which controls cell wall porosity and turgor in plant pathogenic fungi www.science.org/doi/10.1126/... #mycology #plantscience

Dihydroxyhexanoic acid biosynthesis controls turgor in pathogenic fungi

Many plant pathogenic fungi penetrate host surfaces mechanically, using turgor pressure generated by specialized infection cells called appressoria. These appressoria develop semipermeable cell walls ...

In @science.org this week: The interaction between flavonoids and rhizobial Nod factors during legume symbiosis www.science.org/doi/10.1126/... #plantscience

The molecular basis of the binding and specific activation of rhizobial NodD by flavonoids

The specific partnership between legumes and rhizobia relies on a chemical dialogue. Plant flavonoids activate the bacterial transcription factor NodD, which triggers production of Nod factors that ar...
