Time course of fungal colonization by G. cichoracearum in Arabidopsis expressing the two full-length alleles of Vitis STS under control of their native promoters. (A) Schematic representation of constructs used for stable transformation of Arabidopsis thaliana. (B) Expression of macroscopic disease symptoms in T₃ transgenic Arabidopsis compared with the wild-type Col-0 after inoculation with G. cichoracearum at 7 dpi. (C) Time course of leaf colonization by G. cichoracearum followed by histology based on staining with trypan blue; the scale bars refer to each image. C, conidia; H, hyphae; CP, conidiophores.
