The common bean (Phaseolus vulgaris L.) has its origin in America, where it is consider as one of the basic foods. In Cuba, the emergence of bean golden mosaic was associated with high populations of Bemisia tabaci in common bean plantings in the 1970s. Persistent infections and crop losses cause...

Cassava represents a staple food source in Cameroon and in many other tropical countries, as it is effectively able to combat hunger. This study was carried out to: (i) determine the growth characteristics of improved and local cassava varieties in Eastern Cameroon under repeated cultivation, (ii...

Wheat streak mosaic virus (WSMV) and Triticum mosaic virus (TriMV) are economically important viral pathogens of wheat. Wheat cvs. Mace, carrying the Wsm1 gene, is resistant to WSMV and TriMV, and Snowmass, with Wsm2, is resistant to WSMV. Viral resistance in both cultivars is temperature sensiti...

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...

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 (tRNAmeti)-binding site that probably acts as a primer for minus-stran...

Plantas de la variedad SP 71-6163 afectadas por el virus del síndrome de la hoja amarilla de la cana de azúcar (ScYLV), se sembraron en condiciones de invernadero para purificar el agente causal y producir anticuerpos específicos. La metodología de purificación utilizada fue la de Lockhart (1999)...
