3/8 🧬📊 For the first time (or do update us), we've modelled dynamic, plant gene circuits with absolute units for both RNA and protein copies per cell.

You can compare our mathematical models directly to your biochemical data. Over time, both approaches should benefit! #SystemsBiology

4/8 🤖🧪 Those absolute units mean that we can predict the DNA-binding dissociation constants (Kd) of our clock transcription factors in vivo, for example.

After some tricky calibration, we estimated comparable Kd values in vitro from our earlier data and the literature, extending the method to any promoter sequence (more on this later).

So, did they match?

Four years after publishing my work on machine-driven parameter screen of biochemical reactions, it still has zero citations. That makes me sad; I am really proud of this work. So I asked ChatGPT to suggest me hashtags, for another chance to reach readers. academic.oup.com/nar/article/4 #MolecularBiology #BiochemicalReactions #ReverseTranscription #RNASequencing #LabAutomation #GeneExpression #SingleCellAnalysis #HighThroughput #AIinScience #ComputationalBiology #BiotechInnovation #DataDrivenResearch

“we introduce a concept called the gene dosage response curve (GDRC) that relates changes in gene expression to expected changes in phenotype. We show that, for many traits, GDRCs are systematically biased in one trait direction relative to the other and, surprisingly, that as many as 40% of GDRCs are non-monotone, with large increases and decreases in expression affecting the trait in the same direction. “
