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 ...

Response of cassava cultivars to African cassava mosaic virus infection across a range of inoculum doses and plant ages.

PLoS ONE, 2019
Cassava production in Africa is constrained by cassava mosaic disease (CMD) that is caused by the Cassava mosaic virus (CMV). The aim of this study was to evaluate the responses of a range of commonly cultivated West African cassava cultivars to varying ...

Production of virus-free cassava through hot water therapy and two rounds of meristem tip culture

Cogent Food & Agriculture, 2020
Cassava genetic resources are highly threatened by devastating viral diseases. It is therefore important to conserve the specifically farmer-preferred landraces/cultivars that are highly susceptible. The study assessed the efficiency of hot water therapy

Evaluation of susceptibility of cassava germplasm to cassava mosaic disease

Journal of the National Science Foundation of Sri Lanka, 2008
Cassava mosaic disease (CMD) caused by geminiviruses is one of the important diseases of cassava Manihot esculenta Crantz causing severe yield loss. Use of resistant varieties is the most feasible measure to manage virus diseases. Eleven germplasms of cassava including Kirikavadi, MU51 and CARI 555 that are recommended and released for cultivation by ...

Evolution of African cassava mosaic virus by recombination between bipartite and monopartite begomoviruses

Virology Journal, 2012
Background Cassava mosaic disease (CMD) is a major constraint on cassava cultivation in Africa. The disease is endemic and is caused by seven distinct cassava mosaic geminiviruses (CMGs), some of them including several variants.

High-Throughput Virus Screening in Crosses of South American and African Cassava Germplasm Reveals Broad-Spectrum Resistance against Viruses Causing Cassava Brown Streak Disease and Cassava Mosaic Virus Disease

Agronomy, 2022
Screening cassava lines for resistance against viruses causing cassava brown streak disease (CBSD) is cumbersome because of the unpredictable and erratic virus infections in the slow plant infection processes that are frequently not associated with ...

First report of cassava common mosaic disease and Cassava Common Mosaic Virus infecting cassava (Manihot esculenta) in Peru

, 2017
Cassava common mosaic disease (CCMD) can cause root yield losses of approximately 30% (Venturini et al. 2016) in cassava (Manihot esculenta Crantz) and it has already been reported in Brazil, Colombia, Paraguay, and Argentina (Calvert et al. 2012; Di Feo

Emergence of a Latent Indian Cassava Mosaic Virus from Cassava Which Recovered from Infection by a Non-Persistent Sri Lankan Cassava Mosaic Virus

Viruses, 2016
The major threat for cassava cultivation on the Indian subcontinent is cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses which are bipartite begomoviruses with DNA A and DNA B components.
