Let's go EU, and catch up with the rest of the world!
Historic day! 🌾
The #EU agrees on new rules for genomic techniques, paving the way for crops that better resist climate change and pests, deliver higher yields, and need fewer fertilisers & pesticides. A big step towards a more sustainable food system.

New genomic techniques: deal to support the green transition in farming | News | European Parliament
The new rules will make the EU food system more secure and sustainable, with climate- and pest-resistant plants that give higher yields and require fewer fertilisers and pesticides.

New research in #ScienceSignaling visualizes how plant cells generate different patterns of calcium ion waves to respond to microbes and wounds, helping to answer how plants generate diverse responses through this elementary signaling mechanism. https://scim.ag/49NigY0
Local traveling waves of cytosolic Ca2+ elicited by defense signals or wounding are propagated by distinct mechanisms in Arabidopsis
Defense-inducing Ca2+ waves in leaf epidermis are stimulus specific.

👀 Fix your cells prior to protoplasting at optimal temperature for better release. Removal of RNAses is needed for scRNAseq.
Materials can even be frozen 😎

Sounds like a game changer 👌

Very late repost but we loved writing this News and Views article on these super cool papers that enhance our understanding of how the auxin response is fine tuned.
There is a nice News & Views article by @suruchiroy.bsky.social and others regarding our recent Nature Plants paper (@mestelle.bsky.social, @drannisr.bsky.social, and @luciastrader.bsky.social labs) and another from @dolfweijers.bsky.social 's lab. #PlantScience #Auxin rdcu.be/eAEnz
