Las micorrizas arbusculares son asociaciones simbióticas formadas entre un amplio rango de especies de plantas y hongos del orden Glomales. El hongo coloniza el apoplasto y células corticales de la raíz. El desarrollo de esta asociación, altamente compatible, requiere de la diferenciación celular y molecular coordinada de ambos simbiontes, para formar una interface especializada en la cual ocurre la transferencia bidireccional de nutrimentos. Esta revisión resume los resultados obtenidos con el uso de técnicas de biología molecular en el entendimiento del desarrollo de la simbiosis micorrízica arbuscular. [ABSTRACT FROM AUTHOR]

Arbuscular mycorrhizae are symbiotic associations formed between a wide range of plant species and fungi in the order Glomales. The fungus colonizes the apoplast and cortical cells of the root. The development of this highly compatible association requires the coordinate the molecular and cellular differentiation coordinate of both symbionts to form a specialized interface over which bi-directional nutrient transferance occurs. This review summarizes the results obtained using molecular biological techniques in the understanding of the development of arbuscular mycorrhizal symbiosis. [ABSTRACT FROM AUTHOR]
