Transcriptomic prey-capture responses in convergently evolved carnivorous pitcher plants.

ABSTRACT: The Australian pitcher plant Cephalotus and the Asian pitcher plant Nepenthes exhibit striking morphological and functional similarities, serving as compelling examples of convergent evolution. Although trapping pitchers in both lineages represent some of the most elaborate leaf structures in angiosperms, it remains unknown whether their analogous phenotypes share common molecular foundations, especially at the level of gene expression. Here, we conducted tissue-specific RNA-seq experiments coupled with feeding treatments in Cephalotus follicularis, mirroring the available expression dataset of Nepenthes gracilis to analyze gene expression evolution underlying the phenotypic convergence. Functionally equivalent tissues in the two species tended to express similar gene sets, with common tra
