These conditions, added to its use as a substitute for illegal crops in Colombia, led to the increase of the area planted with this product in the 1990´s decade, reaching almost 7.500 hectares. However, this situation recently had a dramatic change due to phytosanitary problems, among which anthracnose (Colletotrichum acutatum) and virosis can be remarked. The latter, according to recent research works, is caused by a complex conformed by, at least, four main viruses (Potyvirus, PLRV, CMV and ToMV) and others, apparently less influential (AMV, ToRSV andf TSWV). Due to the great impact this disease has had on the expansion plans of the tamarillo cultivation in Colombia, this revision introduces a detailed description of the main viral groups associated to virosis, emphasizing the characteristics of their genomes, which is the information base to design tools to detect the viruses.esCorporación Universitaria LasallistaTomate de árbol (Solanum Betaceum)Tomate de árbol - EnfermedadesPolerovirusPotyvirusTobamovirusTomate de árbol - Enfermedades - InvestigacionesTomate de árbol - Enfermedades y plagasArticle
