Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026If you’re interested in: • gene regulatory network evolution • transcription factor promiscuity • predictability of adaptation • or why evolution so often repeats itself give the paper a read and let me know your thoughts. 000
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026The same principles likely extend beyond bacteria. Across life, regulatory novelty often arises by redeploying existing network components - not by inventing new ones. Evolution tinkers with what is already there. 110
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026These findings help reframe crosstalk. Rather than asking “why is crosstalk tolerated?” we should ask: how does crosstalk shape evolvability? 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026Importantly, TF recruitment is not well predicted by: ✗ sequence similarity alone ✗ structural similarity alone ✗ DNA-binding domain similarity alone Context matters more than identity. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026In our system, evolution often proceeds in two steps: 1. mutations increase TF activity/expression 2. subsequent mutations refine binding towards new promoters And which TF is rewired is predictable based on the path of least resistance: the most mutationally accessible route. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026That third point is key. Low-level, non-cognate binding (aka crosstalk) provides the raw material for innovation. Selection doesn’t invent new interactions from scratch. It amplifies ones that already exist weakly. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026Why these TFs and not others? Our work shows three properties matter most: • ability to reach high activity • ability to reach high expression • some pre-existing low-level affinity for new targets 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026Only a small subset of transcription factors can take over the lost function. And they do so in a clear hierarchy of accessibility: some regulators are evolutionary “first responders”. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026When the flagellar master regulator (FleQ) is deleted, bacteria repeatedly evolve motility back - but not randomly. They follow highly predictable evolutionary routes. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026Using experimental evolution in Pseudomonas fluorescens, we can watch regulatory rewiring happen in real time. Delete a master regulator → apply selection → observe evolutionary rescue. 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026This “promiscuous” binding is usually viewed as noise and costly misregulation that cells have evolved to suppress (and that is true for locally adapted organisms!). But what if those mistakes can also matter for evolution? And is it possible to define it's role? 100
Tiffany Taylor @taylorlabgroup.bsky.social · 23/01/2026Gene regulation is often described as neat and deterministic, with each transcription factor (TF) controlling its own specific targets. Reality is messier: They make mistakes; They engage in crosstalk/promiscuous binding 100

Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025A big thank you to my co-authors: Joshua Cherry, @gretelwaugh.bsky.social Also thank you to @peteralind.bsky.social for his helpful feedback on the manuscript and for pointing out that GnT motifs bias experimental evolution surprisingly often! 030
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025Finally, the GnT motif mutation rates determined for Pseudomonas closely match those determined for Salmonella, so we're confident that our calculated rates for GnT motifs can be used to both find and quantify T:A→G:C mutation hotspots in many other species of bacteria. (8/8) 110
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025GnT motifs are very short (≥8bp depending on G tract length), which means these hotspots are very common elements in bacterial genomes! For example, Pseudomonas fluorescens has hotspot GnT motifs that can cause a non-synonymous mutation in ~20% of reading frames. (7/8) 110
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025We also demonstrated that GnT motifs can be used to increase the rate and predictability of evolution. If you synonymously convert the neighbouring nucleotides around adaptive T:A positions into GnT motifs, adaptive evolution can happen significantly faster. (6/8) 110
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025For example, if a G4T sequence (i.e. GGGGT) is flanked by a 5’ AC and a 3’ A, there’s almost no hotspot (the T:A→G:C mutation rate is ~5-fold higher than baseline). But if a G4T sequence is flanked by a 5’ GA and 3’ C, the T:A→G:C rate is ∼1100-fold higher than baseline. (5/8) 120
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025We created T:A→G:C mutational hotspots by synonymously altering: (a) the length of the GnT sequence, (b) the dinucleotide 5’ to the homopolymer G tract, and (c) the nucleotide 3’ to the T. Together, the flanking nucleotides change the mutation rate by orders of magnitude. (4/8) 110
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025In this work, we create mutational hotspots in the Pseudomonas fluorescens genome using synonymous nucleotide changes to alter the GnT sequence and its neighbours. We show that GnT hotspots are determined by a GnT sequence and the nucleotides immediately flanking it. (3/8) 110
Tiffany Taylor @taylorlabgroup.bsky.social · 13/08/2025In a recent paper analysing Salmonella and others, Cherry 2023 found that homopolymeric tracts of G (≥3) with a 3’ T frequently mutate so that the T is substituted with another G: I.e. GGGT→GGGG. This rate increases the longer the G tract (GnT). academic.oup.com/gbe/article/... (2/8)academic.oup.comT Residues Preceded by Runs of G Are Hotspots of T→G Mutation in BacteriaAbstract.
