Fig. 3: Estimation of almond leaf scorch disease progress curve in Majorca.

From: Phylogenetic inference enables reconstruction of a long-overlooked outbreak of almond leaf scorch disease (Xylella fastidiosa) in Europe

Fig. 3

Estimation inferred from the proportion of tree rings infected by Xylella fastidiosa (Xf) at 2-year intervals in 34 sampled almond trees (Supplementary Data 4). a The arrangement of infection proportions (bars) fits the disease progress curve expected in a logistic model. b Infection proportion (y) was log transformed and plotted against the year of the tree rings (blue dots). Disease incidence estimations for 2017 and 2012 were included (orange dots and line). The intersection between the regression line and x-axis at −4,6 (=0.01 disease incidence) provides a rough estimate of the likely time of Xf introduction.
