Figure 4. The majority of coding regions in Arabidopsis are not reduced as a result of DSN treatment.

Abundance of more than 26,000 coding sequences compared between the control genomic library (x axis) and the library normalized with DSN after 22 hrs of renaturation (y axis) is expressed in RPKM. Sequences neither reduced nor enhanced as a result of DSN treatment align along the dotted gray line. The vast majority of coding sequences were at least as abundant in the normalized library as in the control library (for distribution and statistical significance, see Figure S1). Color-coding indicates % GC content. The few coding sequences that were reduced tended to have relatively high GC content (Student t-test P-value = 0.0452).
