The role of small RNAs in susceptibility and tolerance to cassava mosaic disease

A dissertation presented by Sarah Jane Rogans to The Faculty of Science, University of the Witwatersrand, Johannesburg in fulfilment of the requirements for the degree of Doctor of Philosophy in the

Resistance to Sri Lankan Cassava Mosaic Virus (SLCMV) in Genetically Engineered Cassava cv. KU50 through RNA Silencing

Resistance to SLCMV is correlated with post-transcriptional gene silencing because of the production of transgene specific siRNA and this resistance coupled with the desirable yield components in the transgenic lines makes them better candidates for exploitation in theproduction of biomass as well as bioethanol.

Validation of high rates of nucleotide substitution in geminiviruses: phylogenetic evidence from East African cassava mosaic viruses.

High substitution rates estimated for the monopartite tomato yellow leaf curl virus (TYLCV) are confirmed to be representative of multiple begomoviruses, and support the notion that geminiviruses evolve as rapidly as many RNA viruses.

Epidemiology of insect‐transmitted plant viruses: modelling disease dynamics and control interventions

The theoretical bases for these models and their use in evaluating control strategies in terms of the interactions between host, virus and vector are considered here and the applicability and flexibility are illustrated by reference to specific case studies, including the increasing importance of whitefly‐transmitted viruses.

Cassava Mosaic Virus Disease in Ghana: Distribution and Spread

Cassava mosaic disease (CMD) symptoms were recorded in about ninety-six percent (96.4%) of fields surveyed with varying severity, indicating that more CMV strains are being detected in the country.

Epidemiological and molecular characterisation of cassava mosaic geminiviruses and the their effect on yield of cassava in Zambia

The current study showed slight epidemiological variation from previous results in same areas, which underlines the importance of continuous evaluation of the disease in order to develop effective control measures.

Genome‐Wide Association and Prediction Reveals Genetic Architecture of Cassava Mosaic Disease Resistance and Prospects for Rapid Genetic Improvement

Cassava mosaic disease resistance has a narrow genetic basis in breeding germplasm. Evidence suggests two possibly epistatic loci and/or multiple resistance alleles exist at the major QTL. Genomic

Development of a VIGS vector based on SACMV for genomic studies in tobacco and cassava

The results suggest a possible role of NbNOA1 in SACMV disease resistance in N. benthamiana, the model plant system for geminivirus infection studies and the ability of viruses to induce PTGS against their own mRNA was developed.

Development of Appropriate Strategies to Control Cassava Diseases in Ghana

With improved disease control practices and cultivation of the disease-resistant varieties identified, farmers can increase and even double yields of edible roots and improve their incomes and food security.

Disassembly of African cassava mosaic virus.

African cassava mosaic virions were purified by density-gradient centrifugation from infected Nicotiana benthamiana plants and analysed for their stability with respect to pH changes and heat treatment by using electron microscopy, revealing a preferential DNA release from the top and shoulder of the geminate particle.
