Title A name given to the resource OBSERVACIONES HISTOLÓGICAS DE ESTRUCTURAS CELULARES ASOCIADAS A Spongospora subterranea f sp. subterranea EN PAPA HISTOLOGY OBSERVATIONS OF CELLULAR STRUCTURES ASSOCIATED TO Spongospora subterranea f sp. subterranea IN POTATO Creator An entity primarily responsible for making the resource Elena Paola González Jaimes, Liliana Hoyos Carvajal, Marcela Villegas Ochoa Description An account of the resource Spongospora subterranea (Wallroth) Lagerheim f. sp. subterranea Tomlinson, agente causal de la sarna polvosa de la papa, es un parásito obligado el cual por sus características biológicas y reproductivas, posee una gran capacidad de sobrevivencia e infección no solo en su principal hospedero, sino también en diversas especies silvestres. El objetivo de este estudio fue realizar observaciones de estructuras celulares asociadas a S. subterranea f. sp. subterranea en plantas de papa en diferentes estados fenológicos naturalmente infectadas por el patógeno, sintomáticas o asintomáticas. Para este propósito se realizaron observaciones al microscopio de luz haciendo tinción de estos tejidos con azul de tripano, mediante lo cual fue posible identificar todas las fases de S. subterranea en las plantas analizadas. Lo anterior demuestra que en los tejidos radicales de papa, no siempre la presencia de agallas es indicativo de la infección, aun plantas asintomáticas pueden ser portadores de estructuras del protozoo; además, algunas estructuras asociadas a S. subterranea como plasmodios o células únicas, son de ocurrencia común y coinciden con las mencionadas frecuentemente en la literatura también en hospederos silvestres, lo que lleva a proponer la hipótesis de que este es un microorganismo común en suelos, que causa disturbios importantes puntualmente en cultivos de papa y cuyas estrategias de control deben orientarse el conocimiento de la ecología de las interacciones del protozoo, sus hospederos y el suelo.Spongospora subterranea (Wallroth) Lagerheim f. sp. subterranea Tomlinson, is the causal agent of powdery scab in potato and is an obligate parasite, because the biological and reproductive characteristic, it has a great survival and infection capacity in both, natural and wilds host which, can belong in different ecosystems and climatic conditions. The goal in this study was to make observations of cellular associate structures to S. subterranea f. sp. subterranea in potato plants in different phenologycal stages naturally infected by the pathogen, with root galls or symptomless. For this proposal were carried out observations at light microscopy, means by were identified all phases of S. subterranea in all symptomless plants. It was demostrated that in radicular tissues of potato not always galls are indicative of infection, plants without symptoms can have protozoa structures, beside associated structures to S. subterranea as plasmodium an sporangium aggregate, are commonly found and coincident with some structures frequently reporter in wild hosts; this appreciations, allows to propose that this microorganism is common in soils, associated with wild and cultivate species, causing important disturbs specially on potato plants, where control strategies should be oriented towards the knowledge of ecology of interactions protozoa, its host and soil.
