Interpretive Summary: Babaco is an herbaceous tree related to papaya and native to the Ecuadorian highlands. Babaco is grown primarily by small farmers in Ecuador and production has been significantly impacted by viruses. This research is a continuation on describing the viruses associated with babaco. Here we report on two additional new viruses infecting babaco. The full genomic sequence of these new viruses was obtained. With this information we can develop diagnostic assays for these viruses and implement testing that will prevent virus infected material distribution to new orchards.

Technical Abstract: Two new viruses, an ilarvirus and a nucleorhabdovirus, were identified in babaco (Vasconcellea x heilbornii) from a commercial nursery in Ecuador. The tripartite genome consisting of 3,299 nt (RNA 1), 2,675 nt (RNA 2), and 1,802 nt (RNA 3) of the ilarvirus, provisionally named “babaco ilarvirus 1” (BabIV1), is related more closely to counter-parts from apple mosaic virus, apple necrotic mosaic virus, and prunus necrotic ringspot virus, with identities ranging from 67 to 77 %. The genome of the nucleorhabdovirus, provisionally named “babaco nucleorhabdovirus 1” (BabRV1), consists of 12,802 nt showing homology to counterparts from potato dwarf nucleorhabdovirus and joa yellow blotch virus, with 69 and 66% identity, respectively.
