Evolution and Development glyphosate ipomoea purpurea herbicide resistance rapid evolution RNA-Seq transcriptome Human-mediated selection can lead to rapid evolution in very short time scales. The evolution of herbicide resistance in agricultural weeds is an excellent example of this phenomenon, but despite this, over 60% of herbicide resistance studies are basic descriptions of the phenotype rather than an examination of the genetic basis and/or evolutionary processes underlying the trait. Using the tools of artificial selection and RNA-seq, we assessed both the evolutionary response and the potential for gene expression differences of selection lines of the common morning glory, Ipomoea purpurea, that differ in their level of resistance to the herbicide glyphosate. We found that the species rapidly responded to artificial selection—susceptible lines exhibited more damage and had fewer leaves as well as a higher proportion of individuals that died post-spray compared to resistant lines. We identified 19 differentially expressed genes (DEGs) between the selection lines—one of which, a cytochrome P450, belongs to a large plant family of genes involved in xenobiotic detoxification. The DEGs also broadly implicated receptor-like kinases, which were down-regulated in the resistant lines, and other growth and defense genes, which were up-regulated in resistant lines. 2013-10-18 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1378196649 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1378196649 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
