Table 1. Subcellular localization analysis.

ICQ, Intensity correlation quotient; PSC, Pearson’s correlation coefficient. For ICQ, 0 stands for no colocalization and 0.5 stands for high colocalization; for PSC, 1 is total positive correlation and 0 is no correlation (Li et al., 2004; Reguera et al., 2015). Values are means ± se; 14 to 16 fluorescence images taken from seven different seedlings were collected for each statistical analysis.
