Untargeted Metabolomics of Plant Samples using HPLC-DAD and Gaussian Mixture Models Premise: Plants produce millions of different chemical compounds, contributing greatly to their physiology and evolutionary trajectories. Most untargeted metabolomic methods are inaccessible, either d...

My first first author publication is now out on BioRXiv! Super excited to share a new outlook in using the entire UV-VIS spectrum when analyzing plant samples on an HPLC-DAD! Super big thanks to my lab and all those who have helped me get here! www.biorxiv.org/content/10.1...

He expands the use of HPLC-DAD by incorporating the entire absorbance spectra of peaks to gain insight into macroevolutionary correlations of chemical classes and their constituents while increasing the discrimination of classes with similar features via Gaussian Mixture Models

Hey new preprint from the lab and @justingambill.bsky.social’s first-first author paper ‘Untargeted Metabolomics of Plant Samples using HPLC-DAD and Gaussian Mixture Models’ www.biorxiv.org/content/10.1...

Registration open for #Fungal26 genetics-gsa.org/fungal-2026/ at Asilomar.

This but for grants 👀

Can if needed

I do a 3 week lab with the folin assay and botrytis. W1 we go outside pick random plants and assess phenolics to make predictions about defense. W2 infections; W3 assess lesions and reestimate phenolics.

Unpopular opinion 2nd year grad students in same competition as 1st years and UGs always seemed unfair. I’d rather see them keep this and bring back the DDIG

I’m excited to read this! Are y’all gonna be at fungal genetics this year? Im bringing a handful of my grad students and would love to meet up

@melaniemadrigal.bsky.social developed a new software to look at complex growth patterns of hyphal networks. It’s the first of a deluge of papers coming describing the genetic architecture of Botrytis cinerea hyphal networks and their response to host cues & environmental stress

HyPhy: A Skeletonization-Based Approach For Fungal Network Analysis Premise: Traditional methods to quantify mycelial growth rely on destructive sampling to quantify biomass. However, these approaches limit continuous observation and require a large enough mass to mea...

Hey y’all first grad student paper from the lab and @melaniemadrigal.bsky.social ‘s first-first author manuscript. www.biorxiv.org/content/10.1...

Who got the link to them Etsy witches? I have some grants that need funded

When you devote your life to the message that empathy is evil and gun deaths are an acceptable price to pay for gun rights, you shape the world with your words. Maybe Charlie Kirk didn’t expect to be a victim of his own worldbuilding, but his death is consistent with the world he helped create.

Please share! I'm looking for a postdoc. The position is to lead one of the following projects: 1) regulation of plant specialized metabolism by cell fate, or 2) foliar embryogenesis in the succulent plant Kalanchoe.

Labor Day Protest in Lafayette, LA

Molecular mimicry of plant cell-surface immune receptors by fungal secreted leucine-rich repeat proteins Leucine-rich repeat (LRR) receptor-like kinases (LRR-RLKs) are important plant immunity proteins. The wheat pathogen Zymoseptoria tritici produces many virulence effectors during infection; however, m...

Really happy this is out in preprint - Congratulations to @graemekettles.bsky.social @zymohaider.bsky.social, and everyone involved for their hard work completing this study! It examines a Z. tritici effector that is a molecular mimic of plant LRRs, and suppresses PTI www.biorxiv.org/content/10.1...

I feel like such a baddie there’s a waitlist for my Bayesian Stats grad seminar. Honestly thought it was just going to just be my grad students that I forced to take it.

Any ECR folks (esp postdocs) want to review a paper on polyploid gene expression? 🌾

Jasmonate-induced prey response in the carnivorous plant Drosera capensis Drosera capensis is a carnivorous plant native to South Africa. Central to its prey capture and digestive processes is a complex array of biochemical processes triggering the production of both enzyme...

Here's the latest preprint from my group's Drosera capensis project. We investigated what the plant can upregulate from a jasmonic acid signal alone (digestive enzymes) and what it needs raw materials from prey to make (flavonoids, lipids).

Are you an early-career biologist or ecologist who would benefit from an invited seminar? Would you like to come to UMaine next fall or spring to give a talk? Leave a brief comment with some info about what you do. I'm co-hosting our seminar series again, and am filling out our rosters.

#botany2025 has been such a wild ride I have to shout out @melaniemadrigal.bsky.social who won best phytochemistry talk on HER FIRST TALK EVER! for her work on GWA of Botrytis resistance to plant VOCs
