Abstract

Higher plants synthesize an amazing diversity of phenolic secondary metabolites.Phenolics are defined secondary metabolites or natural products because, originally, they wereconsidered not essential for plant growth and development. Plant phenolics, like other naturalcompounds, provide the plant with specific adaptations to changing environmental conditions and,therefore, they are essential for plant defense mechanisms. Plant defensive traits are costly for plantsdue to the energy drain from growth toward defensive metabolite production. Being limited withenvironmental resources, plants have to decide how allocate these resources to various competingfunctions. This decision brings about trade-offs, i.e., promoting some functions by neglecting othersas an inverse relationship. Many studies have been carried out in order to link an evaluation of plantperformance (in terms of growth rate) with levels of defense-related metabolites. Available resultssuggest that environmental stresses and stress-induced phenolics could be linked by a transductionpathway that involves: (i) the proline redox cycle; (ii) the stimulated oxidative pentose phosphatepathway; and, in turn, (iii) the reduced growth of plant tissues.
