Global status of tospovirus epidemics in diverse cropping systems: successes achieved and challenges ahead.
To protect crops from the losses caused by severe tospovirus outbreaks, continued vigilance is required to identify and characterize these emerging toSpoviruses, determine their impact on crop production, understand their epidemiologies and develop, evaluate and implement control measures to reduce their impactOn crop production.

Citrus tristeza virus (CTV) specific RNAs extracted from infected citrus tissue were analyzed by Northern blot hybridization and found that the RNAs for the p20 and p23 ORFs were the most abundant and surpassed the amount of the p25 or capsid protein specific subgenomic RNA. Expand
Maize Lethal Necrosis (MLN), an Emerging Threat to Maize-Based Food Security in Sub-Saharan Africa.
The results of collaborative research undertaken to understand the biology and epidemiology of maize lethal necrosis in East Africa and to develop disease management strategies are summarized, including identification of MLN-tolerant maize germplasm. Expand

The history of Iris yellow spot virus in the USA and the world, epidemiology of IrisYellow spot and the onion thrips vector, and management of Irisyellow spot and thrips are reviewed. Expand
Nucleotide sequence and organization of eight 3' open reading frames of the citrus tristeza closterovirus genome.
A specific four-gene module consisting of thehsp70 protein, the hsp90-related protein, a diverged copy of the CP, and the CP itself was found to be common in organization between CTV and beet yellows closterovirus, indicating that these viruses probably have evolved from a common ancestor. Expand
Watermelon bud necrosis tospovirus is a distinct virus species belonging to serogroup IV
On the basis of the sequence divergence and the previously determined host range differences, the watermelon tospovirus should be considered as a distinct species belonging to serogroup IV. Expand
Emerging Problems of Tospoviruses (Bunyaviridae) and their Management in the Indian Subcontinent.
A polymerase chain reaction method adapted for selective amplification and cloning of 3' sequences of potyviral genomes: application to dasheen mosaic virus.
The potyvirus 3' sequence amplification procedure is simple and rapid, is potentially useful in developing virus specific probes and may be used to differentiate strains and species of potyviruses on the basis of the 3' UTR sequences. Expand
Effect of acibenzolar-S-methyl and imidacloprid on suppression of tomato spotted wilt Tospovirus in flue-cured tobacco
This is the first report of effective suppression of an economically important plant viral disease using Actigard, and potentially offers an alternative and effective management tool for spotted wilt suppression on tobacco. Expand
Phenotypic and Etiological Differences Between Psyllid Yellows and Zebra Chip Diseases of Potato
- V. G. Sengoda, J. Munyaneza, J. Crosslin, J. Buchman, H. Pappu
- American Journal of Potato Research
- 1 February 2010
Although an association between liberibacter and ZC has been established, no pathogen is yet associated with potato psyllid yellows and mechanisms by which psyllID yellows symptoms are induced by the potato psyLLid remain unclear. Expand
