Figure 1.

Expression levels of PLDζ1 and PLDζ2 in Arabidopsis tissues. Total RNA from tissues of 6-week-old, soil-grown plants were used for real-time PCR. A and B, PCR quantification of PLDζ1 and PLDζ2 transcripts, respectively. Transcript levels of each gene were expressed in relation to the UBQ10 gene. Experiments for A and B were repeated with similar results. The bar represents se (n = 3). C and D, Expression levels of PLDζ1 and PLDζ2 as detected by MPSS. The MPSS data were obtained from the Arabidopsis MPSS Web site (http://mpss.udel.edu/at; Meyers et al., 2004).
