The Venus flytrap (Dionaea muscipula) is a carnivorous plant native to the temperate and subtropical wetlands of North Carolina and South Carolina, on the East Coast of the United States. Although various modern hybrids have been created in cultivation, D. muscipula is the only species of the monotypic genus Dionaea. It is closely related to the waterwheel plant (Aldrovanda vesiculosa) and the cosmopolitan sundews (Drosera), all of which belong to the family Droseraceae. Dionaea catches its prey—chiefly insects and arachnids—with a "jaw"-like clamping structure, which is formed by the terminal portion of each of the plant's leaves; when an insect makes contact with the open leaves, vibratio…

Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They have adapted to grow in waterlogged sunny places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published Insectivorous Plants, the first treatise to recognize the significance of carnivory in plants, describing years of his research. True carnivory is believed to have evolved independently at least 12 times in five different orders…

Rapid plant movement encompasses movement in plant structures occurring over a very short period, usually under one second. For example, the Venus flytrap closes its trap in about 100 milliseconds. The traps of Utricularia are much faster, closing in about 0.5 milliseconds. The dogwood bunchberry's flower opens its petals and fires pollen in less than 0.5 milliseconds. The record is currently held by the white mulberry tree, with flower movement taking 25 microseconds, as pollen is catapulted from the stamens at velocities in excess of half the speed of sound—near the theoretical physical limits for movements in plants. These rapid plant movements differ from the more common, but much slowe…

Glutathione induces trap closure for carnivory in Cape sundew.. Charles Darwin was profoundly fascinated by Drosera (sundew plants), which have evolved as flesh-eaters with modified leaves, called traps, to catch small animals yet do not respond to transient mechanical stimuli. Despite Darwin's early insights, and recent advances in characterizing these mechanisms, our knowledge of the signaling molecules underlying prey capture responses remains limited. Here, we identify glutathione (GSH) as an important mediator within the signaling cascade of sundew carnivory, implicated in trap closure in a calcium-dependent manner. We show that prey capture promotes GSH accumulation in sundew leaves,…

Inference of mechanical forces through 3D reconstruction of the closing motion in venus flytrap leaves.. Venus flytrap (Dionaea muscipula) leaves exhibit an exceptionally rapid closing motion that occurs within one second. The rapid closure of outwardly curved leaves is thought to be driven by snap-buckling instability-a rapid transition of an elastic system from one state to another. However, the ability of leaves that do not curve outward to also close suggests that the mechanics of leaf closure are complex and need to be understood using three-dimensional (3D) kinematics. We therefore developed a 3D reconstruction method to quantify the curvatures and displacements of leaf blades using t…

Thermal petiole wounding triggers trap closure in <i>Dionaea muscipula</i>.. The Venus flytrap ( Dionaea muscipula Ellis) is a carnivorous plant that captures invertebrates using an electrically excitable trap mechanism. Invertebrates stimulate trigger hairs, initiating action potentials (APs) that drive rapid closure. Trap lobes are electrically isolated from one another by non-excitable petioles. We examined thermal wounding to leaf petiole's ability to produce detectable electrical activity in the isolated trap and if wounding stimulation is sufficient to trigger closure. Using a within-subject design across 15 mature plants, we compared trap-recorded electrical signals follo…

Insectivorous Plants is a book by British naturalist and evolutionary theory pioneer Charles Darwin, first published on 2 July 1875 in London. Part of a series of works by Darwin related to his theory of natural selection, the book is a study of carnivorous plants with specific attention paid to the adaptations that allow them to live in difficult conditions. It includes illustrations by Darwin himself, along with drawings by his sons George and Francis Darwin. The book chronicles Darwin's experiments with various carnivorous plants, in which he carefully studied their feeding mechanisms. Darwin tried several methods to stimulate the plants into activating their trap mechanisms, including f…

Mechanosensor for Proprioception Inspired by Ultrasensitive Trigger Hairs of Venus Flytrap. Mechanosensors, as the core component of a proprioceptive system, can detect many types of mechanical signals in their surroundings, such as force signals, displacement signals, and vibration signals. It is understandable that the development of an all-new mechanosensory structure that can be widely used is highly desirable. This is because it can markedly improve the detection performance of mechanosensors. Coincidentally, in nature, optimized microscale trigger hairs of Venus flytrap are ingeniously used as a mechanosensory structure. These trigger hairs are utilized for tactile mechanosensilla to…

Endogenous Circadian Rhythms in Plant Bioelectric Signals: Cross-Station Replication and Visitor-Driven Suppression in a Public Exhibition.. We report a cross-station replication of endogenous circadian rhythms in plant bioelectric voltage, recorded continuously for 42 days at three independent sensor stations within a public science exhibition (Phänomena, Dietikon, Switzerland; March-April 2026). Three primrose ( Primula vulgaris ) stations were equipped with custom Biolingo bioelectric sensors (ESP32 + AD8232) and recorded autonomously through approximately 21,000 visitor interactions. We extracted DC-invariant spectral features from 5-10 s voltage windows (n = 78,431 quality-filtered fil…

MSL10 is a high-sensitivity mechanosensor in the tactile sense of the Venus flytrap.. The tactile sense is essential for living organisms. However, the molecular mechanisms of mechanosensing in plants remain unclear. The Venus flytrap (Dionaea muscipula), a carnivorous plant, possesses mechanosensitive organs called sensory hairs. After sensing a touch stimulus, the hair generates an action potential (AP) and a long-range calcium signal that propagate to the leaf blade, triggering leaf movement to catch prey after two successive calcium signals. Here, we show that the MECHANOSENSITIVE CHANNEL OF SMALL CONDUCTANCE-LIKE homologue (DmMSL10/FLYC1) in the Venus flytrap acts as a high-sensitivity…

Venus flytrap-inspired PVDF-based sensitive strain sensor with modulus-tuned design for anisotropic bending recognition.. Polyvinylidene fluoride (PVDF) has attracted extensive attention for flexible piezoelectric strain sensors due to its piezoelectric activity and mechanical robustness. However, practical application in small-strain monitoring occasions remains restricted by limitations such as low intrinsic piezoelectricity. Inspired by the mechanical structure of Venus flytrap's trigger hairs, this study synergistically combines modulus differentiation mechanisms with a coaxial architecture to develop core-shell nanofibers. The fiber structure comprises a rigid Polyamide 66 (PA66) core,…
