New OA Resource: "A single-cell, spatial transcriptomic atlas of the Arabidopsis life cycle" rdcu.be/eBmkU

An extensive single-nucleus and spatial transcriptomic atlas of the Arabidopsis life cycle that represents 10 developmental time points in 6 diverse organs.

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

La série noire (et elle ne fait que commencer !) continue : près de 43°C enregistrés aujourd’hui en France, avec 57 records battus, dont 24 records absolus.
En 2025, 598 records de chaleur contre seulement 15 records de froid.
🔴Soit 40 fois plus de records chauds que froids.

Nice paper! Congrats!

Thank you Andrés! :)

New paper out in @jxbotany.bsky.social with Dawn Nagel and Desmond Cairo! We explore how significance levels from tools detecting oscillatory patterns in time-series data can help identify putative new clock components or primary clock target genes 🕟

Canceling NIH grants is a great example of waste, fraud, and abuse. Even canceling just my grant alone, in year 3 of 5, would be a waste of the more than $1M already given to us for this project. Multiply that by hundreds of grants, and they are just throwing away taxpayer $$$. And for what? +

Up: 5 circles illustrating rivers, floodplains, marshes, estuaries, and mangroves. Down: 4 squares to illustrate how wetlands degradation contributes to floods: 1) a river and a marsh, with natural soils; 2) channelization of the river and drainage of the marsh; 3) land conversion to urban areas and agriculture; 4) heavy rain causes severe flooding. By EffiScientiFig

Happy #WorldWetlandsDay! 💧

Today, let’s celebrate the central role of #wetlands in our lives!

They increase resilience to #ClimateChange, support #biodiversity, filter water & contribute to #foodsecurity.

Preserving & restoring wetlands is essential to limit severe flooding from heavy rainfall.

A huge congratulations to Bob Schmitz and his team for the recent published @cellcellpress.bsky.social paper on spatially resolved multi-omic single-cell atlas of soybean development

Genomic information pathways and their numerical linkages in relation to the Central Dogma. The boxes show different omic levels in Col-0 and Can-0. Black arrows indicate the flow of information implied by the Central Dogma starting from CDS (peach) via gbM (green) to mRNA (light blue), ribosome-associated mRNA (yellow) and finally protein (pink). The strength of Pearson correlation between levels is shown both by the numbers and by the thickness of the corresponding black arrows, and represents the correlation between quantitative expression levels (except in the case of CDS where is represents the correlation derived from the multiple regression codon frequency model, i.e. the square root of the fraction of variance explained). The merged arrows connecting CDS, gbM and mRNA to protein show the result of combining information into a single model; note that their combined correlation of 0.720 is less than the sum of their individual effects. The correlation of tRNA levels (lilac) with genome-wide codon and amino acid frequencies is shown on the left. The correlations between corresponding Col-0 and Can-0 omic levels are shown next to the grey double-headed arrows.

Happy to start 2025 by sharing our new preprint biorxiv.org/cgi/content/... -the first paper from our BBSRC collaborative project with

Soil Organic Carbon Measurement Methods. At the top, 5 methods are mentioned from left to right. * Novel sensor technologies * Hybrid (satellite + high-resolution sensors), a promising approach * Core sampling & lab analysis, the gold standard * Hybrid (satellite + lab) * Satellite imagery Each method is illustrated with corresponding icones : soil with probe and portable device for Novel sensor technologies, soil with soil core sampling going in an erlenmeyer flask, satellite. Below is an indication of accuracy with line thickness, peaking at the center below the core sampling and lab analysis method. Novel sensor technologies present a good accuracy, and satellite imagery a relatively low accuracy. Then drawbacks are quantified with line thickness as well. Greater drawbacks for core sampling & lab analysis, then for satellite imagery, and novel sensor technologies present the lowest amount of drawbacks.

💡 Did you know #soil is the largest carbon reservoir in the terrestrial ecosystem?

🚨 Accurate estimation of soil C is crucial to addressing pressing issues such as #ClimateChange, #FoodSecurity, and #biodiversity conservation.
