Root anatomy and root endophytes in Podocarpus parlatorei (Podocarpaceae).
Root anatomy and root endophytes in Podocarpus parlatorei (Podocarpaceae). Podocarpus parlatorei Pilg. known as “mountain pine” is a tree up to 20 m tall, grows in mountain forests between 1500 and 2000 m asl and is the native only representative of the Gymnosperma in the NOA.

Podocarpus parlatorei Pilg. known as “mountain pine” is a tree up to 20 m tall, grows in mountain forests between 1500 and 2000 m asl and is the native only representative of the Gymnosperma in the NOA. The aim of this study was to characterize the anatomy of the root system and root endophytes in P. parlatoreicomparatively between individuals of Tucuman and Catamarca. We applied conventional histological techniques and staining. The results showed that individuals from both provinces had the same structural feature in the different stages of development, differing in the number of layers in the cortical tissue. We observed the presence of arbuscular mycorrhizal with morphology Arum and Paris, both in root and nodules. For this species is recorded for the first time the presence of cells with non-lignified secondary thickening in the cortical parenchyma of the primary roots and nodules, whose function would be mechanical and absorption. The presence of arbuscular mycorrhizal fungi and dark septate endophytes in P. parlatorei is also reported for the first time for Argentina, and the morphology of these root endophytes is described Podocarpus parlatorei Pilg. conocido como “pino del cerro” es un árbol de hasta 20 m de altura, crece en los bosques montanos entre los 1500 y 2000 msm y es el único representante arbóreo autóctono de Gimnosperma en el norte de Argentina. El objetivo de este trabajo fue caracterizar la anatomía de la raíz y los endófitos radicales en P. parlatorei, comparativamente entre individuos de Tucumán y Catamarca. Se aplicaron técnicas histológicas y tinción convencionales. Los resultados evidenciaron que los individuos provenientes de ambas provincias presentaron la misma característica estructural en los distintos estadios de desarrollo, difiriendo en la cantidad de estratos en el tejido cortical. Se observó la presencia de endomicorrizas arbusculares con los tipos morfológicos Arum y Paris, tanto en raíces como en nódulos. Para la especie en estudio se cita por primera vez la presencia de células con engrosamientos secundarios no lignificados en el parénquima cortical de las raíces primarias y de los nódulos, cuya función sería mecánica y de absorción. Además, se cita por primera vez para Argentina la presencia de hongos micorrícicos arbusculares y de septados oscuros y se describe la morfología de ambos endófitos radicales en P. parlatorei.
