Resumen:
The objectives of this work were to study the structure of the vegetative body of Lophophytum mirabile subsp. bolivianum; analyze the change on roots of Anadenanthera colubrina when they are infected by this parasitic plant, and identify the anatomical changes produced by that parasitism. Lophophytum mirabile plants are formed by a spheroidal- narrower underground vegetative body or tuber, externally has a dark warty surface, lacks epidermis, stomata or trichomes. The central matrix of tuber consists of reserving parenchyma and vascular bundles. Parasitic cells located at the level of root cambium initiates the tubers formation, externally visible as exophyte . On the infected root of A. colubrina, the identity of radial and axial growth of the secondary system it is lost. This leads to the formation of xylem loops that affecting the xylem transport and root development, which stops growing in length and develops a woody gall. Infection of L. mirabile causes profound anatomical changes in developing timber of A. colubrina, which favor the successful of the parasite.
