Abstract/Contents:"Among synthetic auxins, quinclorac is unique for its grass-in-grass specificity, as other synthetic auxins typically provide a range of control over broadleaf species while leaving monocots unharmed. Thus, quinclorac is a useful turfgrass herbicide as it targets weed species (including smooth crabgrass), and leaves the greens (such as bermudagrass or bentgrass) unharmed. Resistance to quinclorac in smooth crabgrass has been identified, and it poses the question of what is the mechanism of resistance? Auxin functions as the regulator for SCFTIR1-mediated degradation of the AUX/IAA proteins, and target-site mechanisms have been identified in other synthetic auxin herbicides on these AUX/IAAs. The inherent tolerance of certain grasses to quinclorac begs the question if there are specific AUX/IAAs that are endowing resistance across grass species. Research was conducted in order to elucidate potential quinclorac-resistance mutations within the AUX/IAA genes of a resistant smooth crabgrass population. Herein we perform a comparative genetic analysis between resistant and susceptible populations of smooth crabgrass via de novo transcriptome assembly and annotation using Trinity and Trinotate, respectively. Sequences corresponding to any auxin-responsive protein IAA were extracted, run through NCBI BLAST for further evaluation, and aligned using Seaview. No known mutations were identified in our alignment of the AUX/IAA proteins, however this research provides a foundation into further studies on the genetic differences between inherently quinclorac-tolerant and susceptible grass species."
