QTL mapping reveals the genetic architecture of loci affecting pre- and post-zygotic isolating barriers in Louisiana Iris

Ballerini, Evangeline S; Brothers, Amanda N; Tang, Shunxue; Knapp, Steven J; Bouck, Amy; Taylor, Sunni J; Arnold, Michael L; Martin, Noland H (2012-06-15)

Abstract Background Hybridization among Louisiana Irises has been well established and the genetic architecture of reproductive isolation is known to affect the potential for and the directionality ...

Tang, Shunxue; Okashah, Rebecca A; Cordonnier-Pratt, Marie-Michele; Pratt, Lee H; Ed Johnson, Virgil; Taylor, Christopher A; Arnold, Michael L; Knapp, Steven J (2009-06-10)

Abstract Background Limited DNA sequence and DNA marker resources have been developed for Iris (Iridaceae), a monocot genus of ...

A high-density genetic map of Arachis duranensis, a diploid ancestor of cultivated peanut

Nagy, Ervin D; Guo, Yufang; Tang, Shunxue; Bowers, John E; Okashah, Rebecca A; Taylor, Christopher A; Zhang, Dong; Khanal, Sameer; Heesacker, Adam F; Khalilian, Nelly; Farmer, Andrew D; Carrasquilla-Garcia, Noelia; Penmetsa, R Varma; Cook, Douglas; Stalker, H Thomas; Nielsen, Niels; Ozias-Akins, Peggy; Knapp, Steven J (2012-09-11)

Abstract Background Cultivated peanut (Arachis hypogaea) is an allotetraploid species whose ancestral genomes are most likely derived from the A-genome species, A. duranensis, and the B-genome ...

Transmission ratio distortion results in asymmetric introgression in Louisiana Iris

Tang, Shunxue; Okashah, Rebecca A; Knapp, Steven J; Arnold, Michael L; Martin, Noland H (2010-03-18)

Abstract Background Linkage maps are useful tools for examining both the genetic architecture of quantitative traits and the evolution of reproductive incompatibilities. We describe the generation of two genetic maps ...

Comparative mapping in intraspecific populations uncovers a high degree of macrosynteny between A - and B - genome diploid species of peanut

Guo, Yufang; Khanal, Sameer; Tang, Shunxue; Bowers, John E; Heesacker, Adam F; Khalilian, Nelly; Nagy, Ervin D; Zhang, Dong; Taylor, Christopher A; Stalker, H Thomas; Ozias-Akins, Peggy; Knapp, Steven J (2012-11-10)

Abstract Background Cultivated peanut or groundnut (Arachis hypogaea L.) is an important oilseed crop with an allotetraploid genome (AABB, 2n = 4x = 40). Both the ...
