Rapeseed (Brassica napus) oil is a major source of vegetable oil around the world. Stem rot disease caused by the necrotrophic fungus Sclerotinia sclerotiorum and silique shattering during harvest are two major contributors to yield loss in B. napus (Zhang et al., 2021). Infection by S. sclerotiorum occurs when ascospores land on detached petals where they germinate and form mycelia that ultimately infects the leaves (Ding et al., 2021). Consistent with this mode of infection, reduced damage from stem rot has been achieved by generating apetalous rapeseed that are resistant to petal-mediated infection (Yu et al., 2016).
