Weeds are important biotic constraints to agricultural production, so herbicides are widely used with agronomic crops as the primary method of weed control. Accordingly, extensive efforts to develop herbicide-resistant (HR) crops have been made using various methods, including clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR/Cas9)-mediated gene editing. Thus far, most of the HR crops developed using gene-editing methods have adopted site-specific mutations of endogenous genes, but rarely by insertion or deletion (indel) mutations. In this study, we attempted to confer herbicide resistance in plants via indel mutations using the CRISPR/Cas9-mediated editing of 5-oxoprolinase 1 (OXP1) gene as a target in Arabidopsis. OXP1 is an enzyme that is involved in 5-oxoproline metabolism and the glutathione recycling pathway. Here, we generated the indel mutants of Arabidopsis using OXP1 editing (oxp1/CRISPR), and verified a reduced sensitivity to sulfamethoxazole (Smex), a sulfonamide herbicide that suppresses the growth of cells by inhibiting the folic acid biosynthetic pathway. In addition, we successfully obtained OXP1-edited plants by screening the transgenic plants on Smex-containing media, suggesting the possible use of OXP1 as a marker for plant gene editing. Subsequent molecular analyses demonstrated the indel mutations on OXP1 in the Smex-resistant Arabidopsis plants. Moreover, the oxp1/CRISPR plants exhibited tolerance to heavy metals, such as cadmium, and another sulfonamide compound, amisulbrom. Therefore, the present study provides a way to confer resistance to sulfonamide compounds in plants by generating indel mutations.
