Vanilla mosaic virus a distinct potyvirus species

The genetic diversity of narcissus viruses related to turnip mosaic virus blur arbitrary boundaries used to discriminate potyvirus species

Narcissus plants (Narcissus tazetta var. chinensis) showing mosaic or striping leaves were collected from around Japan, and tested for virus infections using potyvirus-specific primers. Many were found to be infected with a macluravirus and mixtures of different potyviruses, one third of them narcissus yellow stripe virus (NYSV)-like viruses. Genomes of nine of the NYSV-like viruses were sequen...

Discovery and small RNA profile of Pecan mosaic-associated virus, a novel potyvirus of pecan trees

A novel potyvirus was discovered in pecan (Carya illinoensis) showing leaf mosaic symptom through the use of deep sequencing of small RNAs. The complete genome of this virus was determined to comprise of 9,310 nucleotides (nt), and shared 24.0% to 58.9% nucleotide similarities with that of other Potyviridae viruses. The genome was deduced to encode a single open reading frame (polyprotein) on t...

Pepper yellow mosaic virus, a new potyvirus in sweetpepper, Capsicum annuum Brief Report

A potyvirus was found causing yellow mosaic and veinal banding in sweetpepper in Central and Southeast Brazil. The sequence analysis of the 3′ terminal region of the viral RNA revealed a coat protein of 278 amino acids, followed by 275 nucleotides in the 3′-untranslated region preceding a polyadenylated tail. The virus shared 77.4% coat protein amino acid identity with Pepper severe mosaic viru...

Characterization of cassava vein mosaic virus: a distinct plant pararetrovirus.

Cassava vein mosaic virus (CVMV) was found to be widespread throughout the north-eastern region of Brazil. The complete sequence of CVMV was determined, and the genome was 8158 bp in size. A cytosolic initiator methionine tRNA (tRNA met1)-binding site that probably acts as a primer for minus-strand synthesis was present. The genome contained five open reading frames that potentially encode prot...
