Detection and Identification of the First Viruses in Chia (Salvia hispanica)

Abstract

Chia (Salvia hispanica), an herbaceous plant native to Latin America, has become important in the last 20 years due to its beneficial effects on health. Here, we present the first record and identification of two viruses in chia plants. The comparison of the complete nucleotide sequences showed the presence of two viral species with the typical genome organization of bipartite New World begomovirus, identified as Sida mosaic Bolivia virus 2 and Tomato yellow spot virus, according to the ICTV taxonomic criteria for begomovirus classification. DNA-A from Sida mosaic Bolivia virus 2 exhibited 96.1% nucleotide identity with a Bolivian isolate of Sida micrantha, and Tomato yellow spot virus showed 95.3% nucleotide identity with an Argentine bean isolate. This is the first report of begomoviruses infecting chia as well as of the occurrence of Sida mosaic Bolivia virus 2 in Argentina.

Innovative Crop Productions for Healthy Food: The Case of Chia (Salvia hispanica L.)

“…In a recent experimental trial (Yeboah et al 2014) Fusarium wilt infection on chia has also been observed. Moreover, recently the presence of two viruses infecting chia plants was reported, and the infection was able to determine severe disease symptoms (Celli et al 2014). Also, Celli et al (2014) confirmed that the virus was transmitted by whiteflies, and this confirms the presence of species of Aleyrodidae family on this crop as was observed in our field trials in Southern Italy.…”

Such reports of the occurrence of common diseases highlight the need to assess the appropriate control methods, including pesticides useful for the pests and pathogens identified on this crop.…”

Reconstruction and Characterization of Full-Length Begomovirus and Alphasatellite Genomes Infecting Pepper through Metagenomics

“…Inter-species recombination is an important process during the evolution of begomoviruses and has a role in the emergence of a new strain [57]. ToYSV was the second most abundant species detected infecting pepper and was previously identified in bean and chia in Argentina [56,58]. ToYSV has a wide host range, including Solanaceae, Amaranthaceae, Fabaceae, and Lamiaceae families [59][60][61].…”

Emerging threats of begomoviruses to the cultivation of medicinal and aromatic crops and their management strategies

“…The comparison of the complete nucleotide sequences showed the presence of two viral species with the typical genome organization of bipartite New World begomovirus, identified as Sida mosaic Bolivia virus 2 and Tomato yellow spot virus, according to the ICTV taxonomic criteria for begomovirus classification [31]. DNA-A from Sida mosaic Bolivia virus 2 exhibited 96.1% nucleotide identity with a Bolivian isolate of Sida micrantha, and Tomato yellow spot virus showed 95.3% nucleotide identity with an Argentine bean isolate.…”
