Sweetpotato (Ipomoea batatas) is one of the most important food crops in tropical and subtropical countries. In Sub-Saharan Africa, sweetpotato is mainly produced for consumption and as a source of income by resource-poor farmers. However, their production is limited by severe damage caused by pe...

This flyer describes progress made between June 2014 and July 2015 to develop an easily accessible distribution map of all relevant viruses and virus strains infecting sweetpotato throughout SSA as well as appropriate diagnostic methods and protocols to detect them. It provides details about a ge...
El virus colusivo del camote (SPCV, genero Cavemovirus), el virus del aclaramiento de venas del camote (SPVC, genero Solendovirus) y el virus del enrollamiento de hojas del camote (SPLCV, genero Begomovirus) son virus con genoma de ADN, presentes en el camote en infecciones virales simples o mult...

Food security remains a huge challenge for the millions of Africans dependent on agriculture for their subsistence. A low-level agricultural productivity and a high percentage of poor and undernourished people are common in Africa, particularly in sub-Saharan Africa (SSA). Sweetpotato, Jpomoea ba...

Los sweepovirus forman un grupo dentro del genero Begomovirus que se caracterizan por infectar solo a camote, los cuales comunmente causan infeccion asintomatica, pasando inadvertidos, por lo que su prevalencia y distribucion es desconocida en algunas regiones del mundo. Las infecciones multiples...

Exploiting the use of biotechnology in sweetpotato for improved nutrition and food security: Progress and future outlook.
Sweet potato chlorotic stunt virus (genus Crinivirus) belongs to the family Closteroviridae, members of which have a conserved overall genomic organization but are variable in gene content. In the bipartite criniviruses, heterogeneity is pronounced in the 3'-proximal region of RNA1, which in swee...
