African oil palm ringspot virus (AOPRV) had been previously described as a fovea-like virus associated with a lethal disease of African oil palm (Elaeis guineensis) in South America. The original report was based on partial sequence and a distant relationship between AOPRV and Apple stem pitting ...

The complete nucleotide sequences of RNAs 1 and 2 of Rice stripe necrosis virus (RSNV) were determined and compared to the corresponding genomes of all sequenced, rod-shaped plant viruses. The genome organisation of RSNV RNA1 and RNA2 is nearly identical to that of Beet necrotic yellow vein virus...

The complete sequence office hoja blanca virus (RHBV) RNA4 has been determined, based on the sequence of the corresponding eDNA clones. RNA4 consists of 1991 nucleotides with two open reading frames (ORFs). One putative ORF is located in the 5'-proximal region of the viral RNA4; it encodes a prot...

Cassava Frogskin Disease (CFSD) can cause severe damage to cassava roots and is one of the most important diseases of cassava in Latin America. The principal objective of this study was to identify the causal agent of CFSD. Electron microscopy, viral purifications, double-stranded RNA (dsRNA) ana...

A virus with filamentous particles approximately 750 nm long was isolated from African oil palm (Elaeis guineensis) with `chlorotic ring' leaf symptoms in south-western Colombia. The virus was mechanically transmitted from oil palm to brachiaria, maize, sorghum, and sugarcane (Gramineae) but not ...

A tymovirus was isolated from passion fruit plants with conspicuous yellow mosaic leaf symptoms in Colombia. Partial sequencing of its genome showed that this virus is distinct from other tymoviruses for which nucleotide sequences are available; it had only 60 76% homology with the closest relate...

Rice hoja blanca virus (RHBV) is a major virus disease of economic importance affecting rice in northern South America, Central America and the Caribbean. This is the first report of transgenic resistance to RHBV and the transformation of an indica rice variety from Latin America. Rice transforme...
