Figure 5. Expression of chloroplast- and nucleus-encoded genes in control and salt-grown seedlings.

RNA was prepared from 2-week-old seedlings grown as in Figure 1. cDNA was prepared and the indicated transcript levels were determined by qRT-PCR as described in Materials and Methods using cytosolic 18S rRNA as an internal reference. Steady-state levels of each gene transcript in control grown seedlings were defined as 1. (A) Chloroplast-encoded genes. (B and C) Nucleus-encoded genes. Data shown are average ± SE.
