A. thaliana seedlings injected with airborne fungi can accumulate a high content of anthocyanins. The mechanism involved in fungus-induced anthocyanin accumulation in plants has not been fully described. In this study, the fungus Penicillium corylophilum (P. corylophilum), isolated from an Arabidopsis culture chamber, triggered jasmonic acid (JA), salicylic acid (SA), and anthocyanin accumulation in A. thaliana. Inhibitors of JA and SA biosynthesis suppressed the anthocyanin accumulation induced by P. corylophilum. The anthocyanin content was minimal in both the null mutant of JA-receptor coi1 and the null mutant of SA-receptor npr1 under P. corylophilum stimulation. The results indicate that JA and SA signaling mediated fungus-induced anthocyanin biosynthesis in A. thaliana. P. corylophilum led to different levels of anthocyanin generation in null mutants for MYB75, bHLH, EGL3, and GL3 transcription factors and WD40 protein, demonstrating that multiple MYB-bHLH-WD40 transcription factor complexes participated in fungus-induced anthocyanin accumulation in A. thaliana. The present study will help further elucidate the mechanism of plant resistance to pathogen infection.Haskap (Lonicera caerulea subsp. edulis), a shrub with violet-blue fruits, is distributed mainly in Hokkaido, Japan. Miyama-uguisukagura (Lonicera gracilipes), a species related to Haskap, produces red fruits. Interspecific hybridization of Miyama-uguisukagura and Haskap was performed to introduce novel characteristics in the resulting hybrids. The shape and color of the interspecifi
