Movement Protein of Tobacco Mosaic Virus Modifies Plasmodesmatal Size Exclusion Limit
The tobacco mosaic virus movement protein has a direct effect on a plasmodesmatal function and no evidence of F-dextran metabolism in the leaves of the transgenic plants was found. Expand
Overview of groundnuts research in Uganda: Past, present and future
The Groundnut Department at National Semi-Arid Research Resources Institute (NaSARRI) is mandated to conduct research on groundnuts in Uganda and has endeavored to breed varieties that are high yielding, resistant to major pests and diseases, tolerant to drought, high in oil content and have a short to medium maturity period.

The 30-Kilodalton Gene Product of Tobacco Mosaic Virus Potentiates Virus Movement
It is conclusively demonstrated that the 30-kD protein of tobacco mosaic virus potentiates the movement of the virus from cell to cell. Expand
Groundnut Rossette: A Virus Disease Affecting Groundnut Production in Sub-Saharan Africa.
In many sub- Saharan African (SSA) countries, women predominantly grow and manage the crop and groundnut cultivation has a direct bearing on the overall economic and financial well-being and nutritional status of women and children. Expand
Sequence diversity within the three agents of groundnut rosette disease.
The GRAV CP sequence represents the most likely candidate to use for pathogen-derived resistance in groundnut and may provide effective protection against groundnut rosette disease throughout SSA. Expand
Plasmodesmatal function is probed using transgenic tobacco plants that express a virus movement protein.
Surprisingly, at 32 degrees C, movement of the F-dextrans was inhibited in transgenic plants expressing the wild-type MP gene; however, the inhibition was transient and was no longer detected after 48 hours at this elevated temperature, providing experimental evidence that callose deposition is involved in regulating the molecular size-exclusion limit of plasmodesmata in plants.

Tobamovirus and Potyvirus Accumulation in Minor Veins of Inoculated Leaves from Representatives of the Solanaceae and Fabaceae
The lack of detectable infection of smooth-walled companion or transfer cells from inoculated leaves of bean and pea during a period of known rapid, phloem-mediated movement suggests that some viruses may be able to circumvent these cells in establishing phloems-mediated infection. Expand
Distribution and Characteristics of Groundnut Rosette Disease in Kenya.
First report on the distribution and molecular characterization of groundnut rosette disease complex in East Africa revealed that GRAV-CP sequences shared 97 to 100% and 95 to 98% sequence homology at nucleotide and amino acid levels, respectively, amongst themselves and with the Malawian and Nigerian isolates.

Effects of social network factors on information acquisition and adoption of improved groundnut varieties: the case of Uganda and Kenya
Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on informationExpand
Peanut Research and Poverty Reduction: Impacts of Variety Improvement to Control Peanut Viruses in Uganda
A procedure is developed and applied for predicting ex ante impacts of agricultural research on aggregate poverty, using as an example the poverty-reducing impact of peanut research in Uganda.Expand
