Fig 3. Statistical trends of $\widehat{\lambda }\left(l\right)$ mean and PWF frequencies from partitions S₆ and S₇.

Statistical trends were estimated in forty transgenerational methylome variants from Arabidopsis thaliana [19,35] considering all CDM contexts. (A) and (B), exponential region of $\overline{\widehat{\lambda }}\left(l\right)$ vs l in the range of PWF from 5 to 70 nm for the partitions S₆ and S₇, respectively. (C) and (D), exponential regions of $\overline{\widehat{\lambda }}\left(l\right)$ vs l in the range of PWF from 5 to 80 nm for the partitions S₆ and S₇, respectively. The exponential behavior is consistent with Eqs 22 and (23), which permits the estimation of the DNA persistence length L_p by means of Eq 24. (E) and (F) correspond to barplots for the annotated PWFs from linear regions presented in the panels A and B, respectively (4 to 100 bp ~ 34 nm). The relative frequencies of PWFs were normalized taking into account the overall length of the genomic region occupied by each genomic feature (promoter, exons, transposable elements (TEs), intergenic, etc) in the Arabidopsis thaliana genome. The exponential decay law predicted by Eq 33 was verified (subplots mean of PWF-frequency (f) vs l in panels A to D). The estimated value of the Helmholtz free energy ΔF = RT lnZ(γ) (Eq 34) at 298.15 K of temperature is indicated.
