We still can’t predict much of anything in biology Biology is hard. Yes, even for AI.

Biology is much more complicated than most non-biologists can imagine. And AI is not going to change this anytime soon.

I am convinced that we have massively underestimated the impact of substitution reversions on the amount of molecular positive selection that we are able to see. Large populations will readily have reversing mutations readily available, and gene flow will also reintroduce ancestral alleles.

<i>Microbial Genomics </i> Deputy Editor-in-Chief: Call for Expressions of interest

Our current carbon economy relies on fossil fuels, from which we isolate small organic molecules to produce medicines, plastics, cosmetic, or other chemicals that we use everyday. However, sustainability requires a more biomass-based carbon economy, where we engineer plants to produce precursor molecules, which can then be assembled to desired chemicals that we use daily. Plants have evolved an amazing diversity of metabolites, but these metabolites are not produced in every cell of the plant. Therefore, it is essential to understand how plants can express different metabolic pathways across different organs, tissues, and even cell types. We are interested in the following questions: How are metabolic pathways (especially specialized metabolism) controlled by cell fate? How can we reprogram plant cell fates for biomanufacturing? How can we toggle between differentiated cell states for metabolic engineering and totipotent cell state for genetic engineering?

It's grad school application season! My lab (cxli233.github.io/cxLi_lab/ ) will be recruiting a PhD student via the MPS program at MSU (mps.natsci.msu.edu) for Fall 2026.

Happy to take inquires via email (which can be found in the lab website) if you are applying this cycle.

Genomic correlates of tailocin sensitivity in Pseudomonas syringae Abstract. Phage-derived bacteriocins, also referred to as tailocins, are structures encoded by bacterial genomes and deployed into the extracellular enviro

Here’s published version of our manuscript using GWAS to investigate tailocin sensitivity in Pseudomonas syringae. TL:DR pretty clear LPS is tailocin receptor but also that P.syringae often completely swaps out its entire O antigen biosynth pathway w/ recombination

New preprint!

Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠

Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare!

In Arizona, a fight against a deadly fungus is under threat from Trump’s health policies What one Arizona doctor’s quest to stop valley fever says about America’s preparedness for climate-driven disease.

In the 5 to 10 percent of symptomatic cases where the fungus invades the vital organs, the death rate is as high as 25 percent. The pathogen is so powerful the U.S. army weighed whether to develop it into a bioterrorism weapon in the 1960s.
