🌱Exciting Opportunity! The Jarvis Lab is recruiting a Postdoctoral Research Associate to study the structure and function of the chloroplast-associated protein degradation (CHLORAD) machinery. Application Deadline: 12 noon, 24 November 2026 Apply here: my.corehr.com/pls/uoxrecru...

Preprint Alert! 🚨 Have you ever wondered how highly conserved molecular complexes adapted to ever changing cellular environments? Thrilled to show our work on 26S proteasome evolution in the green lineage. 🌱🧬👇 www.biorxiv.org/content/10.6... A thread🧵

Gene repertoire expansion and cis-regulatory diversification shaped 26S proteasome evolution within a proteostasis-centered network

The 26S proteasome is essential for proteostasis and constitutes one of the most conserved molecular machineries in eukaryotes. Its homeostasis is maintained by a mechanistically conserved feedback lo...

Are plant roots really made up of concentric layers of homogeneous, differentiating cell types? In our new study, out now in @nature.com, we show a more complex picture: two distinct cell states within root lineages, shaped in part by the environment. 🧵👇 www.nature.com/articles/s41...

An environmentally regulated dichotomy in cell lineages of the root - Nature

An environment-regulated state is identified across multiple cell types at the root tip, revealing a shared dichotomy between cells with and without this state.
