In attempted to examine the applicability of PCR-TES for analyzing subcellular localizations of genes, three cellular markers were tested in PCR-TES. PCR-fragments of YFP-mTn (for showing actin filaments) [19], NAG-YFP (for labeling golgi apparatus) [20] and ER-YFP (for showing endoplasmic reticulum) [21] were cotransformed with their correspondent plasmids (p35S- CFP-mTn, p35S-NAG-CFP and p35S-ER-CFP) into epidermal cells of Onion peels and Arabidopsis leaves, respectively. Results demonstrated that PCR-fragments (showing YFP fluorescence) of each cellular marker were expressed as efficient as their correspondent plasmids (showing CFP fluorescence) at their cellular locations (Figure 1C).
