From: Time-resolved dual transcriptomics reveal early induced Nicotiana benthamiana root genes and conserved infection-promoting Phytophthora palmivora effectors

Fig. 7

The promoter of a gene encoding the secreted peptide TIPTOP is upregulated during early biotrophy in N. benthamiana roots. a Representative pictures of beta-glucuronidase (GUS)-stained whole root systems of N. benthamiana transgenics carrying TIPTOPpro::GFP:GUS, non-infected or 16 h after infection with P. palmivora LILI-tdTomato. Stars represent unstained root tips. Arrowheads represent stained root tips. b Representative pictures of infected root tips after GUS staining, showing GUS signal at the vicinity of infection sites (top panels). Uninfected root tips from the same plant do not show any staining (bottom panels). Scale bar is 25 μm. c Representative pictures of GFP signal at the root tip of infected N. benthamiana transgenics expressing GFP:GUS fusion under the control of TIPTOP promoter
