How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social‬ @erc.europa.eu‬ 1/x 🧵 www.nature.com/articles/s41...
Plants monitor the integrity of their barrier by sensing gas diffusion - Nature
A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.

The Cereal Stem Cell Systems Consortium published a comprehensive review in Plant Cell on how meristems shape cereal architecture.
If you are not a fan of cereals except for breakfast, your teaching will still benefit from the amazing figures!

Thus, collectively, we think that the SL signaling pathway is one tool by which plants can modulate their water transport capacity to withstand water deficiency conditions.

Lastly, we saw that drought-induced reduction of vessel element size is hardly happening in SL signaling-deficient mutants and that, thus, drought-induced adjustments of vessel elements is SL-dependent.

As a new direction (at least for us) we then tested the effect of altered vessel formation on water loss and found that more vessels are correlated with enhanced transpiration and that this was not caused by other effects like altered stomata density.

The effect of SL signaling on auxin-related genes seems to be the crucial point here as those genes are clearly over-represented among the SL target genes and elimination of some of the auxin-dependent xylem regulators eliminated enhanced vessel formation in SL signaling deficient mutants.

When identifying SL signaling-dependent genes specifically in radially growing organs, we saw that those genes show changed expression in vascular cells types in the SL receptor mutant d14, suggesting that transcriptional profiles in vascular tissues depend on SL signaling.

Then, we saw that in SL signaling-deficient plants cell type composition is indeed shifted toward vessel elements. This was based on SL signaling in the vasculature and not seen in related signaling mutants and not in mutants with similar branching phenotypes like found in SL deficient mutants.

Thereby, we discovered that SL signaling is differential in radially growing organs with signaling levels being particularly low in cambium stem cells and in developing vessel elements.
