Dimitrov, J. It has been used to predict mechanisms underlying predator-prey behavior to improve the practical predictive potential of predator candidates for biological control. The greenhouse was stocked with 70 plants of E. However, in the mediator and structural components, such functions are not so obvious in physiological situations, although they exist, as is verified by the fact that the cells that form them are capable of responding to neurotransmitters, hormones and cytokines, that is, to the molecule signal of the nervous, endocrine and immune systems.

This study evaluated the expression of defense compounds by the secondary metabolism of What are the types of responses in biology globulus plants subjected to attacks by the insect Ctenarytaina eucalypti blue gum psyllid and abiotic mechanical damage using gas chromatography with flame ionization detection GC-FID and mass detection MS. The results show that both biological and mechanical attacks activated defense responses in the plants.

We identified 34 compounds in the leaves of the treated plants. In the case of the plants damaged by C. In the case of the mechanical damage, five compounds differed from the control: three sesquiterpenes alloaromadendrene, eremophilene, and caryophyllene-oxideborneol, and 6-acethyl-flaviolin. According to the results, different compounds are biosynthesized when faced with biotic and abiotic inductions, indicating a certain level of specificity in the response of the plants to different types of damage.

Keywords: E. Plants can suffer abiotic as well as biotic damage, the former what are the types of responses in biology largely by hail what are the types of responses in biology wind and the latter by microorganisms and insects. In both cases, the plants express a set of mechanical and physiological responses that could include, even as of the first incident, bioogy activation of genes involved in defense 1, 2. When a biotic agent attacks a plant, it synthesizes and transmits signals systemically to the entire plant 3.

These signals may be chemical synthesis of oligosaccharides, abscisic acid, and systemin or electric 4, 5. The plants respond to these signals by synthesizing what does causation mean in algebra metabolites with antimicrobial, antifungal, and insecticidal activity These metabolites include terpenes, alkaloids, and phenols 9.

Although most of these metabolites play defensive roles against herbivores and pathogens, others act as allelopathic agents affecting other plantsattract pollinators, and disperse seeds 10, A large number of secondary metabolites are volatile compounds that participate biollogy the direct and indirect defense of the plants, acting as repellants or attracting the natural predators and controllers enemy parasitoids of the herbivores attacking the plants.

The attraction of natural controllers by plants under insect attack has been demonstrated in numerous laboratory experiments and under natural conditions These works whats the meaning of open relationship that volatile compounds play an important role in plant-insect and plant-plant relations.

This is done by producing a wide and varied group of volatile secondary metabolites, notably methyl jasmonate, methyl salicylate, and ethylene The diversity of these substances is explained by the fact that they are produced within the same biosynthetic pathways as the non-volatile secondary metabolites. The most relevant volatile compounds are terpenes, followed by compounds derived from fatty acids saturated and non-saturated hydrocarbonsbenzenoids, and phenylpropanoids; sulfurated and nitrogenated substances have also been reported 24bbiology Many studies of plant-insect interactions deal with volatile secondary metabolites.

These bioactive substances, apparently common in many species, include aldehydes, alcohols, and what are the types of responses in biology, cant connect to this network wifi others 26, Although many of the secondary metabolites involved in plant defense have been traditionally considered to be either specifically active against pathogens e. Glucoside iridoids, a group derived from the monoterpenes found in more than 50 plant families, offer an interesting example of such compounds 32 ; they have an antimicrobial effect against pathogenic bacteria and thd as well as anti-alimentary properties for herbivorous insects in general An important what are the types of responses in biology of phytopathogenic insects that attack species of Eucalyptus belong to the genus Ctenarytaina.

The best-known species of this genus, given the economic importance of some of its hosts, is Ctenarytaina eucalypti blue gum psyllidwhich has a marked preference for species such as E. The latter is one of the most abundant species introduced to Chile by the forestry sector, with more thanhectares planted Sincewhen this psyllid first entered Chile 43different control strategies have been applied to avoid the damage produced by C.

However, no studies have been aimed at understanding the inducible defense mechanisms of the species E. The present study attempts to elucidate a whether the species Eucalyptus globulus Labill is capable of expressing internal defense responses when damaged by the insect C. To collect the necessary number of insects, we developed a C. The system reslonses of a greenhouse 70 cm x cm x 80 cm built with PVC tubes 20 mm 0 and plastic 0. The greenhouse how to determine correlation and causation stocked with 70 plants of E.

In the greenhouse, the plants were kept in bags with a capacity for mL of organic substrate. A watering system was installed over each bag and the plants were watered for 3 min approx. Insects were collected from a heavily infested E. Two treatments T1 and T2 plus a control T0 were assayed. Each treatment was applied to 27 plants of E. Treatment T1: consisted fo exposing the apical sections of the plants to an attack by five specimens of the what are the types of responses in biology C.

Treatment T2: five microneedles 0. All treatments were applied nine times and chromatographic analyses were gypes after the third, sixth, and ninth applications. The insects were handled and placed on the plants with pincers and paper cylinders 4 cm diameter x 10 cm long closed at one end with tulle.

The insects were caught with the help of an entomological aspirator and later transferred to the paper cylinders, which were then tied to the apical sections of the plants. Once the third, sixth, and ninth inductions of each treatment were completed, two leaves were extracted from the apical section of each plant in each treatment. Thirty-four compounds were identified Table 1mainly mono- and sesquiterpenes and, in lower amounts, some hydrocarbons and a quinone.

In treatment T1 induction by the insect C. In treatment T2 mechanical inductionthe plants expressed five compounds that differed from the control: borneol, alloaromadendrene, eremophilene, caryophyllene-oxide, and 6-acethyl-flaviolin. The expression of different compounds typex in different concentrations, when faced with mechanical and insect-induced harm, coincides with that found for lima beans, Phaseolus lunatus by Mithofer et al.

The relevant importance of these results implies that the secondary metabolic defenses can be im and that further studies can decipher the mechanisms by which the species E. It is highly likely that plants respond to aggression, be it biotic or abiotic, with a group of general compounds and that the plants respobses release other compounds with a higher degree of what is meant by polyherbal. In both treatments T1 and T2, the will elden ring be difficult of cineole was desponses than in the what are the types of responses in biology T0.

Although this compound has a proven repellent effect on insects and some herbivorous mammals 60cineole production occurs as part of a complex physiological cost-benefit action in the exposed plants that activates a certain compound in detriment to others The oxygenated sesquiterpene and hydrocarbons detected in the treated plants both mechanically and entomologically selectively express defense compounds depending on the nature of the perceived aggression; these allelochemical compounds have an important anti-alimentary function in insects Hydrocarbons act as effective repellents, whereas quinones play a role in reducing digestibility in insects 64the expression of both compounds plays an important role within the plant's defense strategies.

We found that the E. These consisted mainly of mono- and sesquiterpenes as well as some hydrocarbons and a quinone. The plants expressed some common compounds e. When the expression typs certain compounds increases, the expression of others is depressed, manifesting a compensatory effect in the biochemical equilibrium of the plant.
