Tomato golden net virus and tomato yellow net virus: two novel New World begomoviruses with monopartite genomes

Two novel tomato-infecting begomoviruses were discovered via high-throughput sequencing in Brazil. Both viruses were also Sanger-sequenced and displayed DNA–A components phylogenetically related to New World bipartite begomoviruses. The names tomato golden net virus (ToGNV) and tomato yellow net vir...

Description
Summary:Two novel tomato-infecting begomoviruses were discovered via high-throughput sequencing in Brazil. Both viruses were also Sanger-sequenced and displayed DNA–A components phylogenetically related to New World bipartite begomoviruses. The names tomato golden net virus (ToGNV) and tomato yellow net virus (ToYNV) were proposed. The majority of the New World begomoviruses has bipartite genomes. However, extensive analyses revealed that ToGNV and ToYNV have monopartite genomes, because no cognate DNA–B components were detected. Hence, they may comprise a unique group of monopartite New World begomoviruses, which have enormous biological, molecular, and plant breeding interest.
