Genetic mechanism of non-targeted-site resistance to diquat in Spirodela polyrhiza

Understanding non-target-site resistance (NTSR) to herbicides represents a pressing challenge as NTSR is widespread in many weeds. Using the giant duckweed (Spirodela polyrhiza) as a model, we systematically investigated genetic and molecular mechanisms of diquat resistance, which can only be achieved via NTSR. Screening the diquat resistance among 138 genotypes suggested more than 8.5-fold resistance differences. Further experiments suggested that diquat uptake and antioxidant-related processes jointly contributed to diquat resistance in S. polyrhiza. Using a genome-wide association approach, we identified candidate genes that are associated with diquat resistance in S. polyrhiza, which includes a homolog of dienelactone hydrolase., , , # Data from: Genetic mechanism of non-targeted-site resistance to diquat in Spirodela polyrhiza

The dataset contains analyses on diquat toxicity for different *Spirodela polyrhiza* genotypes. This dataset includes scripts and raw data files of toxicity test, metabolite analyses and enzymatic assays. Additionally the dataset provides pdf versions of all figures associated with the manuscript plants-2849712. The code and raw data that were used to generate the main figures are stored in the folders \"Figure1\" - \"Figure5\". The names of the folders correspond to the figure names in the manuscript. Code and data used to generate the Appendix figures were deposited in the folder \"Appendix_figures\". We named all data collections of appendix figures \"Figure Ax\", where x corresponds to the number of the appendix figure in the manuscript.The visual documentation (e.g. pictures of cultures) and analysis of the Spirodela genotype screening procedure can be found at raw_data_toxicity_assays_GWAS. ...
