Dasineura asteriae Reprograms the Flower Gene Expressions of Vegetative Organs to Create Flower‐Like Gall in Aster scaber

open access: yesPlant, Cell &Environment, Volume 48, Issue 11, Page 8217-8231, November 2025.
ABSTRACT Plant galls are abnormal growing tissues induced by various parasitic organisms, exhibiting diverse and complex morphologies. Typically, these galls differ significantly in appearance from their host plants. Here, we report that larvae of a parasitic fly generate unique, rosette galls on Aster scaber, a perennial herb. These galls develop from
