In plants, different types of injury and physical damage are commonly referred as wounding. Some organs such as leaves and shoots have cutin as a protective barrier, but once a wound occurs, putative pathogens may gain entrance into the plant through the injured tissue. Consequently, plants have developed orchestrated responses to wounding at the histological, genetic, and biochemical levels resulting in a complex defense mechanism. Therefore, the response to wounding is aimed at restoring the physiological status of the damaged tissue and is critical to prevent further lesions. Interestingly, the classical growth regulator auxin has been implicated in the wounding response. Even though initial reports showed an apparent antagonism between auxin and wounding, novel findings suggest a more intricate relationship between auxin, stress, and other plant defense pathways. Transcriptomic studies carried out in Arabidopsis and solanaceous have offered a wider comprehensive picture on the regulation of auxin-related genes by wounding. In this chapter, we reviewed the participation of auxin-related genes as part of the complex mechanism that takes place during wounding in plants particularly in Arabidopsis thaliana and solanaceous. In addition, we also raised a discussion, about the participation of small molecules downstream wound signal such as NO, ROS, and eATP Información suministrada por el agente en SIGEVAPalabras Clave
