Congratulations, Chloé!

New preprint out! Zhoubo Hu et al "A redox-regulated RCC1-like protein controls catalase activity in Arabidopsis". We identify CAIR1, a UVR8-interacting protein, as a redox-responsive regulator of catalase localization and activity, maintaining cellular ROS balance. 🌱

Plant Kelch phosphatases are Ser/Thr phosphatases involved in cell cycle regulation Brassinosteroids (BRs) are plant steroid hormones sensed at the cell surface by the membrane receptor kinase BRI1. Activation of BRI1 leads to the dephosphorylation of BZR1/BES1 transcription factors ...

Our new year starts of course with new preprint on brassinosteroid signaling tinyurl.com/nhzcfkxd. We re-analyzed the function of Kelch phosphatases, which were previously characterized as protein tyrosine phosphatases that dephosphorylate the critical pTyr200 in the GSK3 kinase BIN2. (1/6)

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Honoured & excited that ‘Breathing Underground’ has been funded by the ERC!
This will let me explore one of the most fundamental questions of plant life: how roots breathe underground? @erc.europa.eu

Well done, Vinay!

Linalool-triggered plant-soil feedback drives defense adaptation in dense maize plantings High planting density boosts crop yields but also heightens pest and pathogen risks. How plants adapt their defenses under these conditions remains unclear. In this study, we reveal that maize enhance...

Out in @science.org The crazy sequence of events from planting maize in dense fields. Density-dependent linalool release triggers release of compounds into the soil affecting microbes and plants.

Happy to share our latest manuscript about Brassinosteroid recognition 😎 hope it offers a broad and intensive understanding of BR ligands--BRI1-LIKE receptors mechanism.

Our latest on brassinosteroid signaling: Ligand binding spectrum, specificity & selectivity of all BR receptors in Arabidopsis. By @albertocaregnato.bsky.social , @hmchen93.bsky.social and our great chemistry collaborators Mirek Kvasnica, Jana Oklestkova and Mirek Strnad.

Ancient hybridization underlies tuberization and radiation of the potato lineage Genomic and functional analyses reveal that the potato lineage originated from a homoploid interspecific hybridization event between the Tomato and Etuberosum lineages 8–9 million years ago. The alternate inheritance of highly divergent parental alleles drove the origin of tubers and explosive species diversification and niche expansion into the high Andes.
