The mechanism of gold nanoparticle formation and genes involved in such processes, especially Au transport in plants are not understood. Previous reports pointed to the probable role of COPT2 in Au transport based on the transcript accumulation of  COPT2  under Au exposure. Here, we provide evidence revealing the additional role of COPT2 for Au mobilization in yeast and  Arabidopsis . The  COPT2  transcripts significantly accumulated in the root of  Arabidopsis  under Au exposure. The expression of  COPT2  restores Cu uptake ability in  ctr1Δctr3Δ  mutants and leads to Au sensitivity in yeast, which is comparable to Cu in growth kinetics experiments. The metal measurement data showed that the Au level was increased in  COPT2 , expressing yeast cells compared to vector transformed control. The  copt2  mutant of  Arabidopsis  displayed a similar growth pattern to that of Col-0 under Au treatment. However, a notable phenotypic difference was noticed in three-week-old plants treated with and without Au. Consistent with yeast, Au uptake was reduced in the  copt2  mutant of  Arabidopsis . Together, these results clearly reveal the Au uptake capability of COPT2 in yeast and  Arabidopsis . This is the first report showing the potential role of any transporter towards uptake and accumulation of Au in plants.

COPT2, a plasma membrane located copper transporter, is involved in the uptake of Au in Arabidopsis
