Abstract: Tamarillo leaf malformation virus (TaLMV) is a potyvirus first discovered in cape gooseberry fields in Eastern, and South-western Antioquia. This virus is responsible for a very damaging disease that has resulted in significant reductions in yields and cultivated area for this crop in Colombia. Tamarillo is frequently co-cultivated with other solanaceous plants but no evidence for cross-pathogenicity of TaLMV has been found until now. In this work, we report a natural infection of cape gooseberry (Physalis peruviana L.) by TaLMV. Infection by TaLMV was detected by RNAseq screening of cape gooseberry fields and confirmed by RT-qPCR and Sanger sequencing. The sequenced genome is 99.3% identical to previously sequenced TaLMV isolates, and evidence suggests that it can accumulate at high loads in this new reported host. RT-qPCR analysis indicates that TaLMV is already widely distributed, can naturally infect other solanaceous hosts and may become an emerging threat to the cape gooseberry agroindustry, the second most important exotic fruit export in Colombia.
