Latex: A Model for Understanding Mechanisms, Ecology, and Evolution of Plant Defense Against Herbivory
Latex is a sticky emulsion that exudes upon damage from specialized canals in about 10% of flowering plant species. Latex has no known primary metabolic function and has been strongly implicated in defense against herbivorous insects. Here we review historical hypotheses about the function of latex, evidence that it serves as a potent defense, and the chemistry and mode of action of the major c...
متن کاملHeavy Metal Stress and Some Mechanisms of Plant Defense Response
Unprecedented bioaccumulation and biomagnification of heavy metals (HMs) in the environment have become a dilemma for all living organisms including plants. HMs at toxic levels have the capability to interact with several vital cellular biomolecules such as nuclear proteins and DNA, leading to excessive augmentation of reactive oxygen species (ROS). This would inflict serious morphological, met...
متن کاملEvolution of plant growth and defense in a continental introduction.
Substantial research has addressed adaptation of nonnative biota to novel environments, yet surprisingly little work has integrated population genetic structure and the mechanisms underlying phenotypic differentiation in ecologically important traits. We report on studies of the common milkweed Asclepias syriaca, which was introduced from North America to Europe over the past 400 years and whic...
متن کاملInduced Plant Defense: Evolution of Induction and Adaptive Phenotypic Plasticity
Induced defenses may evolve in natural plant populations where heritable variation in inducibility affects plant fitness. Although this has not been documented for any plant – parasite system, genetic variation in induction has been recently reported for several plant-parasite systems. Correlations between induction and fitness in variable parasite environments suggest that inducibility may ind...
متن کاملDefense mechanisms in psychological health and sport success of athletes
Introduction: Defense mechanisms represent a crucial component of our capacity to maintain emotional homeostasis. The present study is carried out with the purpose of determining the predictability of psychological health and sport success by defense mechanisms used by elite athletes. Materials & Methods: A sample of 385 (285 male and 100 female) elite at...
