The cover of Vol 76 | Issue 18 | 2025 of the Journal of Experimental Botany. Light green banners border the top and bottom of the page and in the centre is an image of a watercolour painting. "Sapling of North American tree species and common city tree Liriodendron tulipifera (Tulip Poplar). This watercolour painting depicts the young potted trees of this species used in Johnson et al., pp. 5573–5587. Trees were placed in freezers while their leaves were imaged to track ice formation and spread. This research revealed that the pattern of ice spread in these leaves is governed by vein anatomy and provided the first visualisation of freeze-induced xylem embolism (air bubble formation) in leaf veins.

Watercolour painting of a young Tulip Poplar tree on the cover of 'Journal Experimental Botany', for volume 76, Issue 18, 2025

The cover of @jxbotany.bsky.social is my painting of Tulip Poplar, a North-American native & global street tree that was the focus of our paper visualising freezing spread & freeze-thaw embolism in leaves!
A lovely way to finish this multi-year mutli-country project

So fun to be featured on this week’s @naturepodcast.bsky.social talking about the tree microbiome and could not be more thrilled to be following a story on rubber ducks.

A diverse and distinct microbiome inside living trees - Nature Microbiome analyses of living trees show that a single tree can host approximately one trillion bacteria, with microbial communities distinctly partitioned between heartwood and sapwood and with minim...

Congrats to @jgewirtzman.bsky.social on his new paper exploring the microbiome of trees now online in Nature (www.nature.com/articles/s41...). Amazing effort to pull all this data together that highlights the distinct microbial communities in the sapwood and heartwood of different species.

Our new paper describing a novel method for measuring plant cell turgor is now online at PNAS: www.pnas.org/doi/10.1073/...

We demonstrate how nucleating microbubbles inside plant cells and studying their growth and dissolution dynamics allows us to estimate turgor pressure.
