First Report of Sida micrantha mosaic virus Infecting Oxalis Species in Brazil

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

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 begomov...

A type of sugarcane mosaic virus infecting maize,surghum and johnsongrass in iran

Diversity among isolates of cowpea severe mosaic virus infecting cowpeas in northeastern Brazil.

Eleven isolates of cowpea severe mosaic virus (CPSMV), a member of the genus Comovirus, were selected from 50 samples collected of nine cowpea fields in Northeastern Brazil (Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Sergipe, Bahia, and Distrito Federal) and partially sequenced. The RNA1 partial sequence, corresponding to the helicase, viral genome-linked protein, pic...

Yellow mosaic virus infecting soybean in northern India is distinct from the species infecting soybean in southern and western India

Genomic components of the begomovirus causing yellow mosaic disease (YMD) in soybean in Delhi were cloned, sequenced and infectivity proved. Nucleotide sequence analysis of the virus isolate revealed more than 89% identity with Mungbean yellow mosaic India virus (MYMIV) and therefore it is designated as soybean isolate of MYMIV (MYMIV-[Sb]). Total nucleotide and predicted amino acid sequence an...

Detection and characterization of a Cucumber mosaic virus isolate infecting peperina, a species native to Argentina

Minthostachys mollis (Kunth.) Griseb., “peperina”, a member of the family Lamiaceae, is an aromatic species used in modern pharmacology and medicine. It is widely distributed in the Andes, from Venezuela and Colombia to Argentina. In Argentina, the main exploitation area of peperina includes the mountain area of the province of Córdoba, where the plant is indiscriminately harvested, leading to ...
