Gemycircularviruses (genus Gemycircularvirus, family Genomoviridae) are single-stranded DNA viruses that are spread around the world in association with several organisms and environments. In this work, we identified two gemycircularviruses associated with two non-cultivated plants in Brazil, Momordica charantia and Euphorbia heterophylla. Both viruses display the general genome structure of gemycircularviruses. The virus isolated from M. charantia showed the highest nucleotide sequence identity with Pteropus associated gemycircularvirus 5, and an atypical structure consisting of a hairpin embedded in the major stem-loop was observed in the intergenic region. The virus from E. heterophylla showed the highest nucleotide sequence identity with Odonata associated gemycircularvirus 1. Phylogenetic analysis groups the two new viruses together with other genomoviruses of the genus Gemycircularvirus.
