“…These two types of defense are considered as constituting, if they are already present before the infection, or induced, if it results from host-pathogen interaction (BRAGA & DIETRICH, 1987;ZHANG et al, 2013).…”

“…Pathogen mechanisms of penetrating plant parts, either above or below-ground, involve direct access through the surface, wounds or stomata (Zhang et al 2013). On the other hand, phytophagous can harm the plant in different ways due to diverse feeding habits.…”

Taking the best out of plants, namely from medicinal and aromatic plants (MAP), involves understanding their structural and chemical features, in connection with their biological roles, and, no less important, realizing the principles behind their use by plants. Plants are exquisitely sensitive to biotic and abiotic environmental changes. Nevertheless, plants are unique in their renewal capacity, since they can produce meristems during their life time, and in showing developmental plasticity, i.e., the ability to change its development in response to diverse factors. This means that a plant can very often survive, despite having been partially eaten, and/or that a single plant genotype can be expressed under different phenotypes, and the one(s) expressed will depend on local environmental stimuli. From man point of view this may have importance, as these different phenotypes can be associated to different chemotypes, which may have a tremendous implication on the biological activity of plant man-valued products and on their commercial value. Some of the structural and chemical traits involved in plant-abiotic and plant-biotic defence, and in attraction interactions, with some examples on how man uses some of these traits and mechanisms to his benefit, are here revised. Apoplastic barriers, glandular or non-glandular structures, mimicry, plant, or plant parts, movements, abiotic environmental relationships, interaction with pathogens and phytophagous and attraction of pollinators and seed dispersers, are discussed. In each case, plants use both constitutive, as well as inducible traits. Nevertheless, it is noteworthy that constitutive traits are not always constant. Indeed, constitutive structural and chemical features can be permanent or transient, depending on the plant developmental stage. Despite all available traits, plants are endowed with self-defence mechanisms against their own toxins. The awareness of plant structural and chemical adaptative features purposes can complement the knowledge derived from evolutionary studies, and provide us the know-how to project and develop plants with improved traits, or procedures based on their modus operandi and/or better plant (nano-)products.

“…The resistance of different plants to pathogens may be related to the production of primary and secondary metabolites that act as natural antimicrobials [13]. In plant-pathogen interactions, several reactions occur simultaneously, and often the pathogen can overcome the structural and biochemical defenses of the plant in order to colonize its tissue [14].…”
