Epidemiological Analysis of Cassava Mosaic and Brown Streak Diseases, and Bemisia tabaci in the Comoros Islands

Viruses, 2022
A comprehensive assessment of cassava brown streak disease (CBSD) and cassava mosaic disease (CMD) was carried out in Comoros where cassava yield (5.7 t/ha) is significantly below the African average (8.6 t/ha) largely due to virus diseases. Observations

First report of cassava mosaic disease and cassava mosaic geminiviruses in Gabon [PDF]

Plant Pathology, 2004
Cassava mosaic disease (CMD), arguably Africa's greatest plant protection problem, has been known to occur in central/West Africa for more than 70 years. There is, however, no published record of the occurrence of CMD or the cassava mosaic geminiviruses (CMGs) that cause it from the central African country of Gabon.

Evaluation of whitefly population and weather effect of cassava mosaic incidence on commonly grown cassava in Benue State, Nigeria

Journal of Applied Sciences and Environmental Management, 2020
Vector population and weather are critical in virus disease incidence and could be strategic for its management in agriculture. To investigate the influence of whitefly population and weather on Cassava Mosaic Disease (CMD) in cassava, TMS 419 and TME ...

Cassava mosaic geminiviruses associated with cassava mosaic disease in Rwanda

International Journal of Pest Management, 2005
Cassava mosaic disease (CMD), and cassava mosaic geminiviruses (CMGs), were investigated in a country-wide survey conducted in six cassava-producing prefectures (administrative regions) of Rwanda in 2001. CMD occurred throughout the country at an average incidence of 30%. Incidence was highest in Kigali (44%) and lowest in Butare (11%).

Mutations in DNA polymerase δ subunit 1 co-segregate with CMD2-type resistance to Cassava Mosaic Geminiviruses

Nature Communications, 2022
Cassava mosaic disease is caused by geminiviruses and suppresses cassava yields throughout the tropics. Here, the authors show that mutations in MePOLD1, encoding DNA polymerase δ subunit 1, co-segregate with CMD2, the major source of genetic resistance ...
