Happy to finally see my PhD work published in @jxbotany.bsky.social. A big thanks to all the people involved in the work including my mentor @malinowskilab.bsky.social. Feel free to delve in..

SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance www.science.org/doi/10.1126/...

New Article: "A mobile DELLA controls Medicago truncatula root cortex patterning to host arbuscular mycorrhizal fungi" rdcu.be/eJO9O Mobile transcriptional regulators DELLA and SHORT-ROOT control the number of root inner cortex cell layers able to host symbiotic AMF.

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science! (1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Such a lovely title!

Coming to you live from #ISPLORE2025JP Fresh preprint from my lab showing that leaves progressively oxygenate and how this is important for their morphogenesis.Thanks to our collaborators from @Fra_LicO2si lab. #plantscience www.biorxiv.org/content/10.1...

Color changing flowers 🧬🎨- attempt #2 Older flowers (bottom) show dark red/ orange tints whereas young buds (top) display strong fuchsia color. Getting closer..

Looking for some clarity in the labyrinth of terms regarding lateral root initiation (priming, founder cell specification, pre-branch sites, oscillation zone, root clock,...)? Here is our new paper hopefully bringing some light in the darkness: track.smtpsendmail.com/9032119/c?p=...

🌱 What happens when lateral root primordia (LRPs) fail to emerge? Using our new lineage tracing tool LRTracker, Xin discovered that arrested LRPs don’t just disappear—they gradually switch fate and become part of the cambium, contributing to secondary growth.1/x www.sciencedirect.com/science/arti...

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

New preprint! 🐛 Root-knot nematodes hijack root cells, turning them into feeding sites and making plants very sick. Using a cross-species scRNA-seq approach we mapped this process and show how this knowledge can be used to engineer resistant crops.🌱 A summary🧵 : www.biorxiv.org/content/10.1...

New paper: Gibberellins are long-distance regulators of shoot-to-root signalling of the light environment Our latest paper ( published online in Plant Cell, shows that Gibberellins are involved in long-distance signalling of phytochrome-sensed light signals all the way in to the roots that are not…

Friday Flower 001: Mimulus lewisii 🌸✨ Monkeyflowers are masterpieces of design with nectar-guide spots formed by an activator–inhibitor system of MYB transcription factors. These generate reaction–diffusion patterns across the ventral petal.

Pretty little baby...La la !

Thrilled to have our spatial single-cell atlas of the Arabidopsis lifecycle in @NaturePlants. Turns out that its easy to make nice images when spatial expression of 1,000 genes is available! 1/n @natanellae.bsky.social @tatsuyanobori.bsky.social @joeecker.bsky.social www.nature.com/articles/s41...
