Epidermal derivatives as xylem elements and transfer cells: a study of the host-parasite interface in two species of Triphysaria (Scrophulariaceae)

Key Points

• Unique ultrastructural characteristics of epidermis enhance the parasitic strategy in Triphysaria.
• The study identifies distinct haustorium formations that facilitate nutrient transfer between host and parasite.
• Observational analysis showcases the adaptation of xylem elements to enhance parasite-host interactions in these species.
• These findings may indicate broader implications for understanding plant parasitism and host adaptations.
