Resumen
La simbiosis de la micorriza arbuscular está formada por las raíces de más del 80 % de las especies de plantas terrestres y los hongos Zigomicetes del Orden Glomales. Los efectos benéficos de esta simbiosis suceden como resultado de un diálogo molecular complejo entre los socios simbióticos. La identificación de las moléculas involucradas en este proceso es un prerrequisito para una mayor com- prensión de la simbiosis. Hay evidencia de los eventos de señalización-reconocimiento en diferentes estados de las interacciones planta-hongo en la micorriza arbuscular, pero no se conoce la naturaleza de las moléculas señal y los procesos de percepción-transducción. Para conocer el potencial de la micorriza arbuscular en la agricultura sustentable, es preciso identificar las moléculas principales de la interacción planta-hongo. Existen numerosos métodos disponibles para el análisis molecular de los hongos arbusculares que ayudan a comprender la interacción dinámica entre las plantas y éstos.
