Excited to share my latest work in @newphyt.bsky.social. Here, we used TurboID proximity labeling with CLAVATA receptors FEA3 and BAM1D in maize meristems to better understand the signaling pathways important for meristem regulation. #PlantScience

Cryptic variation fuels plant phenotypic change through hierarchical epistasis - Nature Gene regulatory network architecture and complex dosage effects from paralogue diversification converge to shape phenotypic space, producing the potential for both strongly buffered phenotypes and sudden bursts of phenotypic change.

A phylogenetic analysis of the flora of the Alps reveals that the flora is young and colonist rich. Its assembly was primarily driven by the Pleistocene climatic cycles.

Broad application of plant protein tagging with ALFA tag for nanobody-based imaging and biochemical approaches Epitope tags are broadly used for detecting, modifying or purifying proteins of interest, but their breadth of application is often rather poor. Recently, the rationally designed ALFA tag and its ALFA...

DOG1 controls dormancy independently of ABA core signaling kinases regulation by preventing AFP dephosphorylation through AHG1 DOG1’s autonomous signaling pathway allows seeds to regulate dormancy and stress traits independently.

Very happy that our story on dormancy control by DOG1-PP2C is now published in Science Advances. We found that DOG1 prevents the activation of AFPs by AHG1. This is the result of a great team effort led by Guillaume Née. Summary of key findings below🧵 www.science.org/doi/10.1126/... @science.org
