The plant parasitic nematodes are among the most damaging pathogens worldwide, affecting plant growth and yield. The plant responses to damage caused by nematodes is closely related to their food habitat, either ectoparasites or endoparasites, and the type of cell damage such as cell destruction caused by species of Pratylenchus and Radopholus; syncytia, related with species of Heterodera and Globodera; and, giant cells, produced by species of Meloidogyne. The objective of this review was to analyze the scope of current research results on understanding the physiological implications of plant interaction with plant-parasitic nematodes, mainly those that destroy the cell, form syncytia and giant cells. In general, the plant parasitic nematodes, regardless of the type of damage they cause, reduce the physiological functions of the roots by affecting the absorption of water and nutrients, create macro and micro-nutriment imbalances that induce physiological changes in the roots and aerial organs of plants, and produce yield losses. More research is required related with the nutritional status of the plants, when interacting with plant parasitic nematodes, in order to get better physiological responses of the plants, which will allow to have less impact of the parasitism of the nematodes on the plants, contributing to a better the management of these.
