Our lab's new paper is out! We introduce ENTRAP-seq, a high-throughput in planta assay for multiplexed profiling of protein-coding libraries. Using ENTRAP-seq and machine learning, we discovered transcriptional regulators from ~1,500 plant viral genomes. go.nature.com/4pw5cL1

Biological diversity beyond model organisms is poorly represented in ML training datasets. Our new preprint uses a high-throughput assay and active learning to discover and characterize gene regulation in non-model organisms.

Our study shows that existing models perform poorly on sequences from non-model organisms because they are out-of-distribution relative to sequences in model species.

Functional annotations from model organisms are insufficient for robust evolutionary predictions. Active learning across evolutionary space enables generalizable models to accelerate discovery in understudied branches of life. Preprint: biorxiv.org/content/10.1101/…

A truly enabling new approach by Tara Lowensohn, @WillCody_12 and @Sattely_lab to probe plant genetics at scale. Single-gene-per-cell delivery coupled to an effective transcriptional selection system. Libraries in plants. biorxiv.org/content/10.1101/…

Check out our new preprint! We examined sources of variability of transgene expression in N. benthamiana agroinfiltration and ways to minimize it. Graduate student Sophia Tang observed FP expression in >1,800 plants over the course of nearly 3 years! biorxiv.org/content/10.1101/…

Happy to share our new publication out today in @NaturePlants where we quantitatively dissect synergy and antagonism that occurs during Nicotiana benthamiana transient agroinfiltration. Congrats to Simon, Matthew, Mitch and all other co-authors! nature.com/articles/s41477-0…
