Resumen
[EN] Since the emergence of life on Earth, living beings have established complex relationships with
other organisms and with the surrounding environment. These associations
sometimes involve two or more lineages of organisms in which changes in one of these evolutionary
trajectories conditionate the other. This process, called coevolution, occurs between organisms
belonging to the same or different kingdoms and shows a wide spectrum of interactions going from
mutualisms, in which the specialisation benefits both species, to hostile relationships. As sessile organisms, plants are subjected to numerous interactions with different
organisms above- and below-ground, including animals, bacteria, fungi or viruses. Precisely, one of
the first and more successful examples of coevolutionary systems described in literature implies the
interaction stablished between plants and insects. Almost 298 million years ago, during the Permian
period, pollinivory, the consumption of pollen by animals, took place firstly.
Not long after, during early and mid-Cretaceous, pollination driven by insect was already the main
strategy of angiosperm reproduction (Hu et al., 2008). Other examples of plant coevolution include
the development of plant defence strategies against herbivore (i.e. resistance, tolerance, phenological
escape and overcompensation), the recognition of chemical molecules in the mycorrhizal fungi and
rhizobacteria symbiotic interactions, or the competitive genetic race established between the
pathogenic-infection identification systems of plants and the ability of those pathogens to escape from
that recognition.
