The negative influence of N-mediated TMV resistance on yield in tobacco: linkage drag versus pleiotropy

THEORETICAL AND APPLIED GENETICS, 115(2), 169–178.

By: R. Lewis n, L. Linger*, M. Wolff* & E. Wernsman n

MeSH headings : Cloning, Molecular; Genetic Linkage; Immunity, Innate / genetics; Inbreeding; Mutagenesis, Insertional; Plant Diseases / genetics; Plant Diseases / virology; Plant Proteins / genetics; Plant Proteins / physiology; Plants, Genetically Modified / physiology; Plants, Genetically Modified / virology; Tobacco / genetics; Tobacco / physiology; Tobacco / virology; Tobacco Mosaic Virus / physiology; Transformation, Genetic; Transgenes
TL;DR: Comparisons of the 14 corresponding transgenic NN backcross-derived lines with K326 indicated that linkage drag is the main factor contributing to reduced yields in TMV-resistant flue-cured tobacco germplasm. (via Semantic Scholar)

Marker-assisted selection for resistance to black shank disease in tobacco

PLANT DISEASE, 86(12), 1303–1309.

By: E. Johnson n, M. Wolff n, E. Wernsman n & R. Rufty n

author keywords: bulked segregant and RAPD analyses; disease resistance genes; Phytophthora parasitica var. nicotianae
TL;DR: The results demonstrated the efficiency of marker-assisted selection for Ph using a RAPD marker linked in coupling and repulsion, and RAPD phenotypes were stable across generations and ploidy levels. (via Semantic Scholar)

2002 journal article

Origin of the black shank resistance gene, Ph, in tobacco cultivar Coker 371-gold

PLANT DISEASE, 86(10), 1080–1084.

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

author keywords: disease resistance genes; gene phylogeny
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.

By: R. Lewis n & E. Wernsman n

TL;DR: By inserting N in the chromosome, the initiated construction of a disease resistance package by linking the TMV resistance gene with a potyvirus resistance gene(s) native to the chromosome. (via Semantic Scholar)

1997 journal article

Characterization of post transcriptionally suppressed transgene expression that confers resistance to tobacco etch virus infection in tobacco

Plant Cell, 9(8), 1411–1423.

By: M. Tanzer n, W. Thompson n , M. Law n, E. Wernsman n & S. Uknes n

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.
