Legg, J.P.[Whiteflies as vectors of plant viruses in cassava and sweet potato in Africa: Introduction]Whiteflies as vectors of plant viruses in cassava and sweet potato in Africa: Introduction
Autor: Legg, J.P.

Cassava mosaic disease (CMD), recognized in Africa for more than a century, is now known to be caused by a group of geminiviruses in the genus Begomovirus from the family Geminiviridae. All are transmitted in a persistent manner by the whitefly vector, Bemisia tabaci. Structurally, cassava mosaic...

Autor: Legg, J.P.

Cassava is an important crop in many parts of the tropics, but it plays a particularly vital role in sustaining food security in sub-Saharan Africa. Diseases are the greatest biotic constraint to cassava production worldwide. Although the diversity of cassava pathogens is greatest in Latin Americ...


Legg, J.P.[Cassava diseases: ecology and control]Cassava diseases: ecology and control

Cassava diseases are major production constraints wherever the crop is grown. Although diseases will continue to pose a challenge to cassava producers in the immediate future, tremendous progress is being made in developing control tactics. These range from biotechnological approaches for enhanci...

Cassava 'brown streak' disease (CBSD) is an economically important constraint in important cassava-growing areas of East, Central and Southern Africa. In addition to causing a dry necrotic rot in the tuberous roots of infected plants, which can render them inedible, CBSD depresses yields through ...


Legg, J.P.Kumar, P.L.Kanju, E.[Cassava brown streak]Cassava brown streak

The Ipomovirus genus in the family Potyviridae contains five species: Sweet potato mild mottle virus (SPMMV), Squash vein yellowing virus (SqVYV), Cucumber vein yellowing virus (CVYV), Cassava brown streak virus (CBSV), and Ugandan cassava brown streak virus (UCBSV). Sequencing and analysis of To...

Although cassava shows resilience against a myriad of pests and diseases, including several of viral aetiology, two virus disease complexes, cassava brown streak disease and cassava mosaic disease (CMD), are the major yield-limiting biotic constraints to its production in sub-Sahara Africa. Subse...
