Title: A novel deltacryptic virus identified in Allium cepa from Brazil
Author: José Ailton Cruz Macedo Dos Santos, Adriano Márcio Freire Silva, Júlio Carlos Polimeni De Mesquita, Rosana Blawid

Abstract:  This work describes a novel partitivirus genome assembled from RNA-seq data generated from onion tissue from fields in Brazil. A new partitivirus genome composed of three dsRNAs, which was closely related to arhar cryptic virus 1, was assembled from Allium cepa samples from Brazil. The genomic sequences were also identified from available transcriptomic datasets of onion samples from China, Czech Republic, India, South Korea and USA. According to the species demarcation in the Partitiviridae family, the new virus was classified into the genus Deltapartitivirus with the suggested name of allium deltapartitivirus. This is the first report of the occurrence of a cryptic virus in plants of the genus Allium, and therefore, this work contributes to the understanding of the genetic diversity of partitiviruses  that infect the genus Allium.
