📝 What were root genes doing before they started building roots? 🧵

Even plants that don’t have roots have genes to make them, so what is it that these genes are up to?

We found that mixing different wheat varieties can decrease belowground competition at early growth stages, especially under resource limited conditions.

Two-panel figure illustrating root hydraulic conductance in wheat cultivars. Panel (a) shows a line graph of pressure chamber measurements of root hydraulic conductance (Krs) over the years of release from 1900 to 2000, with a downward trend indicated by a dashed line and shaded confidence interval. Panel (b) presents CPlantBox simulations comparing root hydraulic conductance (Krs) over time (in days) for two cultivars: S. Dickkopf (1895) and Tommi (2002), with the older cultivar showing higher conductance.

I wasn't very sure why the handles on Bluesky were so long. Turns out that is a method for identity verification by which you can attach your own custom domain. I've had a website for a long time and was able to combine a couple steps to get LarryMYork.phenotyper.com as my handle. Want your own? 👇

There are many serious, serious ethical issues with this. But also, as a person whose entirely livelihood rests on getting papers published, I'm LIVID. I've had papers rejected because some reviewer didn't understand my stats, and these jokers are getting published despite idiot-level plagiarism.

Home environment predicts root anatomy in Mexican native maize. (a) Random forest (RF) modeling for the ratio of total stele area:total cortical area. Accession point of origin colored by observed TSA:TCA from Burton et al. (2013). Trait-specific significant environmental descriptors used for RF model construction. Smoothed RF predicted TSA:TCA for native Mexican maize. (b) RF predicted vs observed TSA:TCA values for all individuals used in model training and validation. (c) Composite GRANAR representation of observed (obs) and predicted (pred) GRANAR sections for the accessions with the lowest (low, pink) and highest (high, green) observed TSA:TCA. Predicted GRANAR cross-sections use predictions for all traits for which RF models were constructed. Hydraulic properties were estimated with MECHA
