a
All experiments on crop plants were conducted using established cultivars. These cultivars are propagated via self‐fertilization, cloning (e.g., potato), or grafting (e.g., apple), minimizing genetic and phenotypic variation among individuals of the same cultivar.
b
Several studies reported data on multiple parasite genera.
c
Fungal and fungal‐like parasites, including microsporidia and oomycetes.
