Our new study in Nature Plants maps how "multi-tasking" enzymes in plants transfer nitrogen, a key step toward improving crop N use efficiency. 🌱 Big thanks to our collaborators from Max Planck, Hokkaido Univ, & MSU, and for support from @NSF and @DOE. Learn more: rdcu.be/eFOFN #PlantMetabolism

Big news! We are recruiting a postdoc to work on tomatillo evolution: jobs.colorado.edu/jobs/JobDeta.... The clade containing tomatillos and its allies (ca 300 spp) has evolved lantern fruits at least 25 times - we want to know why! Join us @rociodeanna.bsky.social & @caschenck-bio.bsky.social

We identified a novel location for acylsugars, on the fruit surface, widely distributed across the Physalis genus. Paves the way for understanding the cell types and regulation responsible to fruit-surface localized acylsugars in collab with @iochromaland.bsky.social www.biorxiv.org/content/10.1...

From the upcoming #AppsPlantSci special issue: Advances in analyzing & engineering plant metabolic diversity A new spin on chemotaxonomy: Using non-proteogenic amino acids as a test case By Makenzie Gibson, @caschenck-bio.bsky.social, et al. bsapubs.onlinelibrary.wiley.com/doi/full/10.... #botany

Distribution of the non-proteogenic amino acid azetidine 2-carboxylic acid (Aze) across plants. Aze was mapped onto a genus-level phylogeny primarily consisting of plants within the Fabales and Asparagales orders. For literature data (Literature), the size of the circle indicates the number of species and literature reports within each genus, with larger circles indicating more Aze–species associations. The distribution of Aze suggests the pathway has emerged through convergent evolution. Image credit: Gibson et al.

We identified a metabolic complex involved in tomato specialized metabolism, regulating trichome acylsugar biosynthesis. Add this to a growing list of pathways that operate as protein-protein complexes of sequential enzymatic steps www.biorxiv.org/content/10.1...

NSF workers who didn't get fired this morning are sending angry emails to NSF management. Here's one of them:

Plants produce tremendous chemistry to outcompete neighbors for space and resources. We identify the mechanism of action of the plant-produced proline mimic azetidine 2-carboxylic acid, which gets misincorporated during protein synthesis and leads to death of surrounding organisms.
