Based on the established efficient regeneration system for watercress in our laboratory, we optimized the processes of pretreatment, co-culture, and differentiation culture. Through GFP fluorescence and PCR identification, we successfully obtained transgenic watercress with the DR5 gene, which allowed us to investigate the distribution details of auxin in the growth process of watercress. Our findings provide an effective method for gene function research and lay the foundation for innovative utilization of germplasm resources of watercress.
