From: Rice transposable elements are characterized by various methylation environments in the genome
Differential methylation degrees dependent on the distance from the copies of p-SINE1 and TabitoII. Based on the band sizes in the TD profiles of the Msp I-digested samples, the fragments were divided into two groups: one ranging from 60 to 200 bp and the other ranging from 200 to 500 bp. Methylation degrees were estimated for the fragments in these two ranges and the fragments in the full range from 60 to 500 bp. Within a 500-bp range from the elements, the proximal regions of both p-SINEI and TabitoII are markedly methylated compared with the distal regions. This tendency was also found in the individual rice strains, as illustrated for Japonica (including A58, T65, and Nipponbare), Indica (IR36, Kasalath, and #108), and O. rufipogon (W107, W593, and W630) along with the overall degrees.
