“…One including genera such as Snli,~, Querc.us, and EucnIyptus forms exclusively epidermal Hartig nets (Godbout and Fortin 1983); the other, such as Cistus and Dryns, forms full cortical Hartig nets (Debaud et a]. 1981;Giovannetti and Fontana 1982). A continuum of Hartig nets from the deeply cortical to the superficially epidermal is thus expected to be encountered in angiosperms.…”

“…Other species used in truffle culture (Quercus L., Corylus L. and Ostrya Scop.) begin carpophore production between the fifth and eighth year of cultivation, depending on the species (Giovannetti and Fontana 1982;Granetti et al 2005). Cistus shrubs can also collaborate with trees in the symbiotic mycorrhization process and in the survival of the mycelium of Tuber melanosporum.…”

“…Giovannetti and Fontana (1982) describe an experimental cultivation of Cistus incanus L. with Tuber melanosporum. After 2 years, the Cistus reached a height of 40 cm and formed characteristic burns (the term ''burn'' refers to the phytotoxic capacity of Tuber melanosporum and its ability to create clearings in the vegetation where its carpophores bear fruit).…”

“…En cualquier caso, junto a las Ericáceas, es una de las familias más importantes en el mantenimiento de nuestros ecosistemas mediterráneos actuales. La versatilidad nutricional es alta, habiéndose constatado numerosos simbiontes fúngicos (Giovannetti & Fontana, 1982;Comandini & al., 2006), que a su vez forman ectomicorrizas con muchas otras especies de plantas. Singular atención merece la relación dual entre Helianthemum spp.…”

ResumenHonrubia, M. 2009. Las micorrizas: una relación planta-hongo que dura más de 400 millones de años. Anales Jard. Bot. Madrid 66S1: 133-144.Se define el concepto de micorriza en un sentido amplio, como una simbiosis no necesariamente mutualística, para incluir las relaciones tróficas de hongos micorrícicos con plantas "inferiores" y plantas aclorofílicas. Se realiza una revisión bibliográfica sobre el origen y diversificación de las micorrizas. Se evidencia el carác-ter pionero de la micorriza arbuscular formada por los Glomeromycota y se resalta su importancia en el proceso de 'terrestrialización'. Se comenta la formación cronológica de los restantes tipos de micorrizas. Se denota la evolución independiente y recurrente de las ectomicorrizas, formadas por Basidiomycota y Ascomycota inicialmente saprófitos, que sugiere una versatilidad en las estrategias nutricionales de estos hongos, como respuesta adaptativa a los cambios ambientales. Similares respuestas debieron ser la causa del origen de las singulares micorrizas ericoides, arbutoides y heliantemoides. Se expone la particular relación trófica entre plantas aclorofílicas como Monotropa o de orquídeas en sus fases hetrotróficas con sus hongos simbiontes. Finalmente, se comenta la reciente evolución de sistemas radicales micotróficamente independientes. The concept of mycorrhiza is considered in a wide sense, as a not necessarily mutualistic symbiosis, covering the trophic relations of mycorrhizal fungi with "inferior" and achlorophyllics plants. A bibliographical review of the origin and diversification of mycorrhizae is made. The pioneering characteristics of the arbuscular mycorrhiza formed by Glomeromycota are discussed, emphasizing its importance during the terrestrialization processes. The chronological appearance of the other types of mycorrhizas is discussed. The independent and recurrent evolution of the ectomycorrhizas formed by Basidiomycota and Ascomycota is discussed; their saprobiont or parasite origin points to the versatile nutritional strategy of these fungi, in adaptative response to environmental changes, as does the origin of the singular ericoid, arbutoid and helianthemoid mycorrhizas. The particular trophic relation between achlorophyllic plants, such as Monotropa and orchids, in their heterotrophic phases, with their "mycorrhizal" fungi is also described. Finally, the recent evolution of the non mycotrophic root systems is commented on.Key words: Mycorrhizae, origin, evolution, symbiosis. Definición y concepto de micorrizasEl término micorriza, que literalmente significa "hongo-raíz", fue propuesto por Frank (1885), para definir asociaciones simbióticas ("vivir conjuntamente dos o más organismos"), mutualistas, no patógenas, entre raíces de plantas y micelios de hongos, en las que ambos resultan beneficiados.Actualmente, el concepto de "micorriza" se considera en un sentido más amplio, para dar cabida a aquellas asociaciones simbióticas hongo-planta que no se establecen en raíces, sino en otros órganos de contacto, especializados p...
