JARAMILLO ZAPATA, Margarita María; ALVAREZ, John Alejandro  e  MARIN MONTOYA, Mauricio. Charactyeristics of the viruses related to virosis of tamarillo (Solanum betaceum)in Colombia. Rev. Lasallista Investig. [online]. 2012, vol.9, n.1, pp.115-127. ISSN 1794-4449.

Tamarillo is one of the fruit crops with the highest potential for being intensively produced in the Colombian Andes, because it has a great quantity of organoleptic and nutritional characteristics interesting for food industries and for the national and international fresh fruit markets. 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 (Colletotríchum 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.
