2002 article

Origin of the Black Shank Resistance Gene, Ph, in Tobacco Cultivar Coker 371-Gold

Johnson, E. S., Wolff, M. F., Wernsman, E. A., Atchley, W. R., & Shew, H. D. (2002, October 1). Plant Disease.

By: E. Johnson n, M. Wolff n, E. Wernsman n, W. Atchley n & H. Shew n

author keywords: disease resistance genes; gene phylogeny
topics (OpenAlex): Plant Pathogens and Resistance; Plant-Microbe Interactions and Immunity; Plant Parasitism and Resistance
TL;DR: Testcross populations of hybrids between burley lines homozygous for Ph and L8, possessing Phl from N. longiflora, showed that Ph and Phl integrated into the same tobacco chromosome during interspecific transfer, and Random amplified polymorphic DNA (RAPD) analyses of the testcross progenies confirmed that recombination between the two loci was occurring.

1997 article

Characterization of Post-Transcriptionally Suppressed Transgene Expression That Confers Resistance to Tobacco Etch Virus Infection in Tobacco.

Tanzer, M. M., Thompson, W. F., Law, M. D., Wernsman, E. A., & Uknes, S. (1997, August 1). The Plant Cell, Vol. 9, pp. 1411–1423.

topics (OpenAlex): Plant Virus Research Studies; CRISPR and Genetic Engineering; RNA and protein synthesis mechanisms
TL;DR: It is shown that at early times in development, immune lines are susceptible to TEV infection and accumulate full-length CP mRNA, and a hypothesis for transgene/viral RNA degradation in which RNA degradation occurs in the cytoplasm while in association with polyribosomes is presented.
