The fast touch-induced folding of leaves in sensitive plants may function for deterring herbivores, but it relies on energetically costly action potentials and interferes with photosynthesis. Here, we tested whether the intensity of the folding response in Mimosa pudica was modulated based on previous experiences, and whether the modulation was dependent on the probability of exposure to herbivores or pollinators. Younger leaves (under higher herbivory risk) reopened faster with repetitions but…

The Role of Leaf Movements for Optimizing Photosynthesis in Relation to Environmental Variation
TLDR
The presence of rapid leaf movements in a number of commercially important crop species suggests that incorporation and modification of these properties may have potential to improve both productivity and stress resistance in cultivated species.
Photosynthetic opportunity cost and energetic cost of a rapid leaf closure behavior in Mimosa pudica.
TLDR
The reproductive allocation costs incurred by M. pudica can be attributed to a combination of photosynthetic opportunity cost and the energetic cost associated with increased stimulation of leaf movement and that behavioral plasticity has the potential to alter photosynthesis opportunity costs.
Mechanical leaf damage causes localized, but not systemic, changes in leaf movement behavior of the Sensitive Plant, Mimosa pudica (Fabaceae) L.
A small number of species, including Mimosa pudica, use rapid leaf movement as a presumptive defensive strategy. How movement-based defenses change in response to mechanical damage and whether chan...
Potential Defense From Herbivory by Dazzle Effects and Trickery Coloration of Variegated Leaves
Two types of defensive coloration theoretically and practically related to and even quite overlapping with masquerade are various types of military dazzle and trickery coloration. Dazzle and trickery
Bioherbicidal Properties of Parthenium hysterophorus, Cleome rutidosperma and Borreria alata Extracts on Selected Crop and Weed Species
TLDR
Parthenium hysterophorus was the most phytotoxic among the tested plant extracts and could be used for developing a new natural herbicide for green agriculture.
Violaxanthin cycle kinetics analysed in vivo with resonance Raman spectroscopy
Measuring the kinetics of the violaxanthin cycle imposes an experimental challenge. Traditionally, carotenoid analysis was carried out laboriously with high-performance liquid chromatography. In this
Resonanz-Ramanspektroskopie an Carotinoiden in Algen zur Bestimmung der Kinetik des Violaxanthinzyklus
This thesis describes the first in vivo approach to directly measure the kinetics of the violaxanthin cycle using resonance Raman spectroscopy. The violaxanthin cycle is a regulation mechanism within
Plants learn and remember: lets get used to it
TLDR
While providing a convenient primer for the study of habituation in a wide range of species and paradigms, this framework may not be taken as a set-in-stones rule manual but rather as an evolving guide.
Towards mimicking biological function with responsive surface-grafted polymer brushes
Abstract Responsive or smart polymer brushes undergo pronounced changes in their surface properties and conformation in response to changes in their environment, including variation in temperature,

Applying Behavioral-Ecological Theory to Plant Defense: Light-Dependent Movement in Mimosa pudica Suggests a Trade-Off between Predation Risk and Energetic Reward
TLDR
Findings suggest this sensitive plant Mimosa pudica balances the risk and reward of antiherbivore behavior in relation to current environmental conditions and that behavioral-ecological theory is a useful framework for understanding plant responses to predators.
Convergence in defense syndromes of young leaves in tropical rainforests
In tropical forests, the majority of damage by herbivores or pathogens occurs on young leaves, yet the patterns of damage and the factors that influence them are poorly known. By measuring damage
Leaf dynamics, self-shading and carbon gain in seedlings of a tropical pioneer tree
TLDR
The leaf position at which photosynthetic capacity was predicted to reach zero was positively correlated with the number of leaves on the shoot, supporting the hypothesis that leaf numbers are regulated by patterns of self-shading.
HERBIVORY AND PLANT DEFENSES IN TROPICAL FORESTS
TLDR
Folivorous mammals do less damage than insects or pathogens but have evolved to cope with the high levels of plant defenses and, along with insect herbivores, may contribute to the maintenance of tree diversity.
In touch: plant responses to mechanical stimuli.

  • 2005
TLDR
Molecular genetic methods may enable elucidation of mechanisms of touch perception, signal transduction and response regulation, and identify genes that encode calcium-binding, cell wall modifying, defense, transcription factor and kinase proteins.
Direct and ecological costs of resistance to herbivory
TLDR
It is found that many more studies have documented costs of resistance (sensu lato) than found during the 1996 survey and that eighty-two percent of studies in which genetic background is controlled, demonstrate significant fitness reductions associated with herbivore resistance.
Dynamic anti-herbivore defense in ant-plants : the role of induced responses
TLDR
It is suggested that induced responses to herbivory are common in ant-plants and non-nectary mediated ant recruitment should also occur, but may be restricted to tightly linked ant-plant systems.
Transient knockout of photosynthesis mediated by electrical signals.
TLDR
The results provide evidence for a role of the electrical signal in the regulation of photosynthesis because the high speed of the signal transduction rules out the involvement of a chemical signal, and the photosynthetic response occurs after the arrival of the Electrical Signal in the leaf pinna.

TLDR
This work describes a wealth of information on the induction of various plant biochemical responses to environmental stimuli but found a limited body of literature on the reversibility of induced biochemical responses.
