🎤Hi #dendrometer users! You are invited to join our new Dendrometer Network (catchy name still tbd 😜). Online meeting 10:30-12 CET Friday 12 Dec. Please share and let me know if you want to join and I will send the meeting link 🌴🎄🌳🌲

Many people think about cold in Northern Europe if the Atlantic Ocean current system #AMOC fails. But that wouldn’t be the only problem for Europe by far.
This new study shows that severe drought is another one. 🌊

Like math and plant community ecology?

I am recruiting one or two new Ph.D. students to work on theory and its integration with data in the areas of forest dynamics, species coexistence, or plant community ecology more generally.

Deadlines for the EEB and Plant Biology programs are Dec. 1.

JOB ALERT! We are looking for a LAB MANAGER (7-year position!) to help us build the MOLECULAR BIODIVERSITY lab in our @terra-cluster.org at @unituebingen.bsky.social. Are you a NGS wet lab expert, and you like the idea of supporting research on natural biodiversity, then apply!

Please re-post!

Do you study effect of disturbance on large scales? Use Belowground Persistence Types of plants! We hope that they will help us to understand better ecosystem resilience than only plant traits.

Single-nucleus transcriptomics revealed auxin-driven mechanisms of wood plasticity to enhance severe drought tolerance in poplar - Genome Biology Background Drought significantly affects forests and woody crops by limiting their growth, increasing their susceptibility to diseases, and reducing productivity. Wood anatomical plasticity is a crucial adaptive mechanism that enables trees to cope with fluctuations in water availability. During severe drought, trees develop more and narrower vessels, enhancing hydraulic safety and reducing the risk of embolism. However, the molecular regulation of vessel formation is still not well understood. Results Using single-nucleus transcriptomics, we have generated a cell type-specific gene expression map of the mature poplar stem under well-watered and drought conditions. Our findings reveal extensive gene expression reprogramming in xylem-forming cells, with changes in auxin homeostasis identified as a key mechanism for anatomical adaptation. Specifically, we show that poplar WAT1-like genes control vessel spatial patterning. Additionally, the downregulation of WAT1-like gene expression in the dividing cells of the vascular cambium and the upregulation of MP-like gene expression in cells undergoing early vessel differentiation facilitate the formation of secondary xylem with narrower and more numerous vessels under drought. Furthermore, the wat2 mutant exhibits greater drought tolerance than wild-type trees, underscoring its potential for developing drought-resilient tree varieties. Conclusions This study provides the first single-nucleus transcriptomic map of hybrid poplar stems under severe drought, uncovering auxin-driven hormonal networks that regulate xylem plasticity and enhance drought tolerance. These insights provide valuable targets for improving resilience in poplar and other woody species.

How do trees survive severe drought? 🌳 In this work performed at @cbgpmadrid.bsky.social , we used single-nucleus RNA-seq on mature Populus stems to reveal the genetic switches that reshape wood anatomy, helping trees stay resilient under severe drought stress.

There is a clever backstop lever to prevent that, of which we made ample use.

This was our office for the day with Jirka Bednařík as we tried out a couple new ways to drill minirhizotron holes.

It's good news for the caprecaillie and bad news for us: the petrol auger was more of a hazard than a use. Quieter methods worked better.

Tree plumbing is hard. Xylem “pipes” must move water & not collapse. New study in #PlantCell&Environment (shorturl.at/CPF9s) led by #MichaletzLab PhD candidate @milossimovic.bsky.social shows how #mechanics (not just #hydraulics) shape xylem traits from leaves to roots, across 5 spp & 600k conduits.

Why throwing all potential predictors into your model and letting it decide has, and always will, be bad for inference.
