| Abstract/Contents: | "RNA-Seq analysis was conducted to evaluate differetial expression in 2,4-D resistant and susceptible buckhorn plantain (Plantago lanceolata) 24 hours after 2,4-D treatment. As no mutations of interest in auxin perceiving repressor or receptor proteins were identified, our hypothesis was that enhanced metabolism of 2,4-D in resistant biotypes was the causal mechanism of resistance. In general, the susceptible biotype enriched numerous GO terms associated with parasitism, pathogen infection, and miscellaneous external biotic stress whereas such GO terms were not enriched in the resistant biotype. Two auxin associated GO categories were also enriched in susceptible, auxin efflux transmembrane transporter activity (GO: 0010329) and auxin transmembrane transporter activity (GO: 0080161), whereas no auxin-associated GO categories were enriched in resistant. Contrary to our hypothesis of enhanced metabolic-based non-target site resistance, more gene level transcripts of cytochrome-P450s, glutathione S-transferases, and ABC transporters were upregulated in the susceptible biotype than the resistant biotype. Further analysis is being conduted to evaluate possible target site based resistance due to changes in auxin receptor or repressor proteins not identified in the initial analysis. While the exact mechanism of resistance has not been discovered, the expression pattern differences between resistance and susceptible biotypes presents a unique differential cascade of events following 2,4-D treatment." |
