Abstract Background Fertilization in flowering plants depends on the early contact and acceptance of pollen grains by the receptive papilla cells of the stigma. Deciphering the specific transcriptomic response of both pollen and stigmatic cells during their interaction constitutes an important challenge to better our understanding of this cell...

Abstract The epidermis is the first barrier that protects organisms from surrounding stresses. Similar to the hyphae of filamentous pathogens that penetrate and invade the outer tissues of the host, the pollen germinates and grows a tube within epidermal cells of the stigma. Early responses of the epidermal layer are therefore decisive for the...

Both the pollen tube and hyphae of filamentous pathogens penetrate the outer layer of the host and then grow within host tissues. Early epidermal responses are decisive for the outcome of these two-cell interaction processes. We identified a single cell type, the papilla in the stigma of Arabidospis, as a tool to conduct a comprehensive...
