Involvement of receptor potentials and action potentials in mechano-perception in plants
The mechanisms of responses to mechanical stimuli of these plants are considered and progress in studies of the receptor potential in characean cells is discussed.
Simulation of action potential propagation in plants.
Functional-morphological analyses of the delicate snap-traps of the aquatic carnivorous waterwheel plant (Aldrovanda vesiculosa) with 2D and 3D imaging techniques.
The motile zone close to the trap midrib, which is thought to not only promote the fast trap closure by hydraulics but also the subsequent trap narrowing and trap reopening, is described and discussed for the first time in its entirety.
Electrical signals in higher plants: Mechanisms of generation and propagation
The mechanism of the distribution the action potential is similar to nerve impulse transmission, while generation of the variation potential is induced by transfer of a chemical substance, whose propagation is accelerated by a hydraulic wave.
Comparative kinematical analyses of Venus flytrap (Dionaea muscipula) snap traps
Stark evidence is presented that adult Dionaea snaps similarly fast in aerial and submersed states and, hence, is potentially able to gain nutrients from fast aquatic prey during seasonal inundation and corroborating the assumption that growth takes place on certain trap lobe regions.
Resting electrical network activity in traps of the aquatic carnivorous plants of the genera Aldrovanda and Utricularia
Interestingly, more complex electrical activity was found in traps than in trap-free organs, supporting the hypothesis that the nature of the electrical activity may reflect the anatomical and functional complexity of different organs.
Bio-inspired compliant mechanisms for architectural design : transferring bending and folding principles of plant leaves to flexible kinetic structures
This thesis proposes innovative concepts that integrate hitherto neglected structural behaviors, such as bending and buckling, into novel design and fabrication processes and offers an alternative to the prevailing paradigm of rigid-body mechanics.
Spread the news: systemic dissemination and local impact of Ca²⁺ signals along the phloem pathway.
It is argued that Ca(2+)-triggered systemic signalling occurs in partly overlapping waves and may trigger the fabrication of signals such as phytohormones, proteins, or RNA species released into the sap stream after product-related lag times.
Calcium as a Trigger and Regulator of Systemic Alarms and Signals along the Phloem Pathway
This chapter explores how Ca2+ transmembrane movements of individual cells along the phloem pathway could collectively act as a basis for systemic signalling. Sieve elements play a pivotal role in
