2.3. Quantitative real-time PCR analysis
qRT-PCR analysis was performed as described by Chen et al.
(2011). The sequences of all primers used for qRT-PCR were listed
in Supplementary Table 1. All qRT-PCR were normalized using the
cycle threshold value corresponding to MaRPS4 which was selected
as reference genes according to our previous study (Chen et al.,
2011). The relative expression levels of the target gene were
figured out with the formula 2
DDCt
. Three independent biological
replicates were performed in the analysis.
