The latest work by @margaridasampaio.bsky.social is out as a preprint!
Using an eQTL dataset for the fungal wheat pathogen Zymoseptoria tritici, we asked whether new regulatory mutations had a predominant effect towards up- or downregulation.
Fig. 10. Subcellular localization of six Zymoseptoria tritici effectors in Nicotiana benthamiana leaf cells expressed without their putative signal peptides.
To investigate infection phase-specific gene expression in #Zymoseptoria tritici, Sandra V. Gomez-Gutierrez et al. analyzed gene expression during infection of susceptible and resistant wheat cultivars, as well as the nonhost species barley: https://doi.org/10.1094/MPMI-07-25-0090-R
Do we really understand how complex systems evolve? Based on experimental evolution in stable vs fluctuating temperature conditions, we show that adaptive mutations in the fungus Zymoseptoria tritici are (i) massively pleiotropic, and (ii) opposed to the phenotypic plasticity.

What did I make my colleagues do today?
1) Invoke Zymoseptoria god
2) Gather ingredients for a wheat-shoot/fungi omelette
3) Measure the impact of early inoculum removal on epidemics to estimate the max effect expected from consumption by springtails
(all sound crazy but one is true)

Fig. 4. Lesion growth plotted against lesion area and lesion age. Yellow curves represent linear or nonlinear quantile regression fits; green lines show loess-smoothed trends. X axis limits were set to display all data points within the 99th percentile; models were fitted, and predictions are shown only within this range, due to limited data beyond this threshold. All coefficients of the regression models were statistically significant (P < 2.2 × 10−16).
Using deep learning-based image analysis, Jonas Anderegg et al. tracked 6,889 individual lesions caused by #Zymoseptoria tritici on 14 wheat cultivars across two field seasons, enabling 27,218 precise measurements of lesion growth in the field: https://doi.org/10.1094/PHYTO-05-25-0187-R
