Figure 4. Expression patterns of eight post-translational modification genes in six developmental stages during nodulation by qRT-PCR.

The six stages are: 0 dai, 4 dai, 10 dai, 14 dai, 18 dai, and N20. Data were normalized to 18S rRNA (R. pseudoacacia) expression and are presented as mean ± SEM and calculated over biological replicate (n = 2) and technical replicate (n = 3) mRNA.
