The rapid trap closure of Dionaea muscinula Ellis has been explained by either a loss of turgor pressure of the upper epidermis, which should thus become flexible, or by a sudden acid-induced wall loosening of the motor cells. According to our experiments both explanations are doubtful. Objections against the turgor mechanism come from the determination by extracellular measurements from the upper epidermis of action-potential amplitudes before and after trap closure. Neither time course nor… 
Kinetics and Mechanism of Dionaea muscipula Trap Closing1[C][OA]
TLDR
The cumulative character of electrical stimuli points to the existence of electrical memory in the Venus flytrap and the observed fast movement can be explained by the hydroelastic curvature model without invoking buckling instability.
Gravity Affects the Closure of the Traps in Dionaea muscipula
TLDR
The results suggest that gravity has an impact on trap responsiveness and on the kinetics of trap closure and how the Venus flytrap could be an easy and effective model plant to perform studies on ion channels and aquaporin activities, as well as on electrical activity in vivo on board of parabolic flights and large diameter centrifuges.
Morphing structures of the Dionaea muscipula Ellis during the trap opening and closing
TLDR
The Venus flytrap is a marvelous plant that has intrigued scientists since the times of Charles Darwin and the most recent Hydroelastic Curvature Model is applied to the analysis of this movement during closing and opening of the trap with or without a prey.
Trap closure and prey retention in Venus flytrap (Dionaea muscipula) temporarily reduces photosynthesis and stimulates respiration.
TLDR
The first experimental evidence for energetic demands and carbon costs during insect trapping and retention in carnivorous plants is put forward, providing a new insight into the cost/benefit model of carnivory.

TLDR
Several key improvements to the elastic models that have recently been introduced to elucidate these movements are described, including a precise mechanism for the action of the motor cells of Aldrovanda and the facts that the opening of the leaves of Dionaea is an irreversible mechanism based on growth and that the strain field is anisotropic are taken into account.

How the Venus flytrap snaps
TLDR
This study identifies an ingenious solution to scaling up movements in non-muscular engines and provides a general framework for understanding nastic motion in plants.

Leaf Closure in the Venus Flytrap: An Acid Growth Response
The rapid closure of leaves in the Venus flytrap (Dionaea muscipula) involves irreversible cell enlargement, which can be initiated by acidifying the cell walls to pH 4.50 and below. Leaves
The Role of ATP in Mechanically Stimulated Rapid Closure of the Venus's Flytrap.
TLDR
It is concluded that ATP is probably the native source of potential energy for contraction of the trap's midrib, and that if the endogenous ATP titer is increased by oxidative phosphorylation or an exogenous source, the trap will close faster.
Versuche und Hypothese zur Primärwirkung des Auxins beim Streckungswachstum
TLDR
The findings suggest that auxin induces a proton accumulation in a cell wall compartment and, as a consequence, enzymatic cell wall softening, which may be the last step in the process of cell elongation.

TLDR
Structural information about these walls of the aquatic alga Nitella axillaris Braun is presented and this information will relate this information to other descriptive facts of wall development in Niteella.

TLDR
The results indicate that the apoplast is a major pathway for the migration of K(+) and Cl(-) within the pulvinus.
The action potential of Dionaea muscipula Ellis
TLDR
The view that the high mechanosensitivity of the sensory hair results from its anatomy and not from a specialized perception mechanism is stressed, it is proposed that trap closure is triggered by a rise in the cytoplasmic concentration of Ca2+ or a Ca2-activated regulatory complex, which must exceed a threshold concentration.
Enhancement of wall loosening and elongation by Acid solutions.
TLDR
It is shown that the pH response can be clearly separated from the CO(2) response, and certain other aspects of the growth and wall-loosening responses, are described.
