Tissue adhesion between plant species occurs both naturally and artificially. Parasitic plants establish intimate relationship with host by adhering tissues at roots or stems. Plant grafting, on the other hand, is a widely used technique in agriculture to adhere of two Here we found that model Orobanchaceae parasitic Phtheirospermum japonicum can be grafted interfamily species. To understand molecular basis tissue distant species, conducted comparative transcriptome analyses infection grafting P. Arabidopsis. Despite different organs, identified shared gene expression profile, where cell proliferation- wall modification-related genes are up-regulated. Among commonly induced showed encoding secreted type β-1,4-glucanase plays an important role for parasitism. Our data provide insights into commonality parasitism plants.
