C6 transcription factors are involved in the infection process of B. cinerea. a Phylogenetic analysis of C6 transcription factors in B. cinerea. The alignment of C6 transcription factor sequences was conducted using Clustal W. The phylogenetic tree was constructed by MEGA 11.0 using the Neighbor-Joining method, and bootstrap test was carried out by 1000 replications. The gene ID highlighted in yellow are the genes for subsequent study. b The expression of six C6 transcription factor genes during the infection process of B. cinerea. Tomato fruits were inoculated with B. cinerea conidial suspension. The relative expressions of 6 C6 transcription factor genes were detected at 0, 8, 12, and 24 h post inoculation (hpi), respectively. Vertical bars represent standard errors of the means. Columns with different letters indicate significant differences (P < 0.05)
