- 8 June 2005
This study rendered 61 useful SSRs that were located in pre-existing genetic maps, fingerprinted in a set of 30 cultivars from South America, North America, and Europe or a combination thereof, validates the use of transcribed sequences as a source of markers.
Potato virus Y: An Evolving Concern for Potato Crops in the United States and Canada.

North American potato production differs from other geographical regions such as Europe in that it is essentially a closed system, i.e., seed potatoes are not imported and production is dominated by…
A Multiplex PCR Assay to Characterize Potato virus Y Isolates and Identify Strain Mixtures.

- BiologyPlant Disease
- 1 July 2006
A single multiplex RT-PCR assay that can assign PVY strain type and detect mixed infections with respect to the major strain types is reported here, and 16 mixed infections were distinguished that had previously gone undetected.
Whole genome characterization of Potato virus Y isolates collected in the western USA and their comparison to isolates from Europe and Canada

- BiologyArchives of Virology
- 7 February 2006
This is the first confirmation by whole-genome sequencing that “European”-type strain variants of PVYN and PVYNTN are present in North America, and the first reported full-length sequence of a tuber necrotic isolate of PVyn:O.
NE-11 represents a new strain variant class of Potato virus Y
- J. Lorenzen, P. Nolte, D. Martin, J. Pasche, N. Gudmestad
- BiologyArchives of Virology
- 12 January 2008
The characterization by whole-genome sequencing of four PVY isolates with unique combinations of molecular and symptomatic characteristics are described, including one of “type B”, which contains an extra recombination event in the 5′UTR/P1 cistron.
Effect of High Temperature on Plant Growth and Carbohydrate Metabolism in Potato
- A. Lafta, J. Lorenzen
- Medicine, BiologyPlant Physiology
- 1 October 1995
There was no interaction of temperature and genotype with regard to the enzymes examined; therefore, observed differences do not account for differences between genotypes in heat susceptibility.
Serological Properties of Ordinary and Necrotic Isolates of Potato virus Y: A Case Study of PVYN Misidentification
- A. Karasev, O. Nikolaeva, S. Gray
- BiologyAmerican Journal of Potato Research
- 1 February 2010
It is demonstrated by a variety of methods that the PVYO-O5 is a variant within the ordinary PVY strain (PVYO), and the limitations of the commercially available monoclonal antibodies should be considered in any certification or phytosanitary testing program.
Hypersensitivity and Egg Drop: A Novel Mechanism of Host Plant Resistance to Colorado Potato Beetle (Coleoptera: Chrysomelidae)
- N. Balbyshev, J. Lorenzen
- Biology
- 1 April 1997
It appears that detachment of Colorado potato beetle eggs with subsequent deposition on the ground could be considered a new mechanism of host plant resistance to insects.
Sequence characteristics of potato virus Y recombinants.
- Xiaojun Hu, A. Karasev, C. Brown, J. Lorenzen
- BiologyJournal of General Virology
- 1 December 2009
Potato virus Y (PVY) is one of the most economically important plant pathogens. The PVY genome has a high degree of genetic variability and is also subject to recombination. New recombinants have…
Transgenic expression of the rice Xa21 pattern-recognition receptor in banana (Musa sp.) confers resistance to Xanthomonas campestris pv. musacearum.
- Jaindra Nath Tripathi, J. Lorenzen, O. Bahar, P. Ronald, L. Tripathi
- Biology, MedicinePlant Biotechnology Journal
- 1 August 2014
Results indicate that the constitutive expression of the rice Xa21 gene in banana results in enhanced resistance against Xcm, and demonstrates the feasibility of PRR gene transfer between monocotyledonous species and provides a valuable new tool for controlling the BXW pandemic of banana.
