Gene expression landscape of leaf cell populations in transgenic tobacco (Nicotiana tabacum) using scRNA-seq. (a) Uniform manifold approximation and projection (UMAP) plot showing the four main cell types of leaf cell populations. (b) Violin plot of selected marker genes and anti-HER2 VHH-FcK gene. Each marker gene represents, from top to bottom, mesophyll, epidermal, adaxial pavement, vasculature, and guard cell types and the anti-HER2 VHH-FcK gene, respectively.
