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.
