Plant material
A total of 100 emerged O. crenata shoots, comprising 10
different plants from 10 populations, were collected from agricultural
fields in Northern Algeria during spring of 2015. The details for each
population, including collection site name, GPS coordinates, and host
are displayed in Table 1 and Figure 1. The sampling was conducted with
the objective of capturing the geographic range of O. crenata in
Algeria, as well as host diversity. To this end, six populations were
collected from faba bean hosts that represent the predominantly affected
crop, and four populations were taken from other host species, carrot,
chickpea, pea, and tomato.
