We test this part in BY-2 tobacoo cell line. BY-2 tobacoo cell is a protoplast that is much easier for us to work with compared to agrobacterium-mediated transfection. First we construct this part in vector PSAT6. It has a promoter CAMV35S that act as a consitiutive promoter in plat cells. To see if the dimeric FYVE protein domain really binds to PI3P receptor on the endosome of plant cell, we added a Phosphoinositide-3-kinase(PI3K) inhibitor, wortmannin, that can inhibit PI3K from turning PI3P precursor into PI3P.

The picture on the left shows that after we introduce dimeric FYVE into BY-2 tobacoo cell line, the FYVE concentrated in endosome and cell membrane. However, one hour after we added 10-6M wortmannin, dimeric FYVE redistributed in cytoplasm.
