Interpretive Summary:

Technical Abstract: Mangoes (Mangifera indica) are an economically important tropical/subtropical fruit, with world production exceeding 40 MT. The U.S. has played an important role in the global mango industry through germplasm conservation and the development of new commercial varieties. To characterize the virus communities in mango trees, high throughput (HTS) sequencing was done on total RNA from leaves of 188 accessions held in the USDA-ARS mango germplasm collection in Miami FL, the world’s largest and most diverse collection. The prominent viruses detected through a metatranscriptomic analysis using Phytopipe were Mangifera indica latent virus (MILV), and unclassified species in the Tombusviridae, Botourmiaviridae, and Totiviridae families. Members of Narnaviridae, Nodaviridae, and Mitoviridae were also detected in the collection, along with three unclassified viruses belonging to the realm Riboviria. This study serves as the first investigation of viral communities in Mangifera indica, and the first report of MILV in the U.S. Based on its abundance in the dataset, the effect of this virus on mango plants warrants further investigation. Although previous literature reported no symptoms related to MILV infection, gene expression studies showed significant stress and defense responses in infected plants. Correlation between virus presence via RT-PCR and symptoms will be discussed.
