Fig. 2. When PARK genes are expressed.

Data from published papers was normalized to peak expression and then plotted in order to provide a gross comparison of the timing of expression of PARK genes(Petersen et al., 1999; Kuhn et al., 2004; Westerlund et al., 2008; Wang et al., 2012; Giesert et al., 2013; Beccano-Kelly et al., 2014; Bjorkblom et al., 2014; Choi et al., 2016). Colors are assigned by Groups defined in Table 1.
