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

UK wheat faces a serious new threat: yellow rust has overcome Yr15 resistance in major varieties. A BBSRC /DEFRA Rapid Response led by JIC with Niab and RRes as partners is hunting new resistance genes to protect harvests. 🌾 www.niab.com/news-views/n...
