Mutational analysis of mechanosensitive ion channels in the carnivorous Venus flytrap plant.

ABSTRACT: How the Venus flytrap (Dionaea muscipula) evolved the remarkable ability to sense, capture, and digest animal prey for nutrients has long puzzled the scientific community.¹ Recent genome and transcriptome sequencing studies have provided clues to the genes thought to play a role in these tasks.^2,3,4,5 However, proving a causal link between these and any aspect of the plant's hunting behavior has been challenging due to the genetic intractability of this non-model organism. Here, we use CRISPR-Cas9 methods to generate targeted modifications in the Venus flytrap genome. The plant detects prey using touch-sensitive trigger hairs located on its bilobed leaves.⁶ Upon bending, these hairs convert m
