COLARICCIO, Addolorata et al. First occurrence of Dasheen mosaic virus (DsMV) in Xanthosoma riedelianum (Mangarito) in Brazil. Rev. mex. fitopatol [online]. 2023, vol.41, n.2, pp.310-318.  Epub 11-Ago-2023. ISSN 2007-8080.  https://doi.org/10.18781/r.mex.fit.2303-3.

Xantosoma riedelianum, also called “mangarito” in Brazil, is an unconventional food plant (UFP) of the Araceae family native to tropical America. Foliar samples of the X. riedelianum showing mosaic, mottle and vein clearing symptoms were collected in the municipality of Monte Alegre (São Paulo State). Transmission electron microscope observations, mechanical transmission to experimental plants, serological (DAS-ELISA) and RT-PCR analyzes indicated that the symptoms could be associated with the presence of dasheen mosaic virus (DsMV, Potyvirus). This is the first report of DsMV in X. riedelianum in Brazil.
