🎉 New: Perennial Roots, Lasting Structure: How Silphium perfoliatum alters pore structure to shape carbon storage and water flow
🔗 www.sciencedirect.com/science/arti...

Excited to share the results of L. Rohlmann’s thesis.

Sometimes soils remember what we forget. 🌾

Over 40 years ago, researchers in the former GDR carried out large-scale experiments with meliorative fractional deep tillage (mFDT) — designed to loosen compacted soils and improve rooting conditions. A Thread on our new publication.

Root-Pore Interactions, the Underestimated Driver for Rhizosphere Structure and Rhizosheath Development

Online now: onlinelibrary.wiley.com/doi/10.1111/...

🔑 Takeaway: In soils, roots shape their rhizopsphere more by where they grow than by what they do to soil structure.

🌱 Insights:
Root‐Pore Interactions, the Underestimated Driver for Rhizosphere Structure and Rhizosheath Development
Using X-ray computed micro-tomography, we show that root growth preferences, rather than root-induced modifications, primarily shape rhizosphere porosity in intact soils, while rhizosheath formatio...

Always nice when experiments with students turn out well. Looking for root adaptations (architecture, phosphatase, mycorrhiza) after localised P addition
Rhizobox with roots of zea mays. On the left side of the box a rectangle is drawn depicting the area where P-fertilizer was added. Roots in this rectangle show much more lateral roots compared to the rest of the box.

#PlantScienceClassics #19: Root gravitropism: 120 years ago the starch-statolith theory was described, ~100 years ago the Cholodny-Went theory proposed, and 25 years ago the directional auxin flow was mapped as reverse fountain in the root tip. #Phytohormones #Gravitropism #Auxin #PlantScience
The title pages of the three papers: "Ueber die Art der Wahrnehmung des Schwerkraftreizes bei den Pflanzen" by Bohumil Řehoř Němec (1900), "Ueber die Perception des geotroplschen Reizes" by Gottlieb Johann Friedrich Haberlandt (1900), and "AUX1 regulates root gravitropism in Arabidopsis by facilitating auxin uptake within root apical tissues" by Alan Marchant et al. (1999). On the left, an sketch from Haberlandt, showing a set of cells from a root that was tilted by 13 degrees. The starch granules are visible inside the cells and have shifted from the center to the corners of the cells that is now pointing down along the gravitropic force. On the right is a sketch from Marchant, showing a root tip with arrows that indicate the auxin flow: Down toward the QC inside the vasculature, then out to the sides and back up toward the shoot in the outer tissues. When the root is slightly tilted, the shoot-ward auxin flow is redirected to the lower side, where it inhibits cell elongation. Hence, the cells on the opposite side elongate more, which leads to root bending.

Sparked by a question by @mud-maik.bsky.social: 2014 I published a study that nicely demonstrats how much particulate organic matter #POM can be contained in a small size fraction <6.3µm!!!, many people now bluntly call mineral-associated organic matter #MAOM, check it out: tinyurl.com/POMvsMAOM

Brilliant tips for explaining research to non-scientists.

Having to answer the "So what do you ACTUALLY do?" question at family gatherings is what got me into #SciComm in the first place - I wish this was the case for more researchers.
