Significance We describe the spatial and temporal profiles of soybean Arabidopsis seed methylomes during development. CHH methylation increases globally from fertilization through dormancy in all parts, decreases following germination, targets primarily transposons. By contrast, CG- CHG-context remains constant throughout Mutant seeds lacking non-CG develop normally, but have a set up-regulated transposon RNAs suggesting that increase may be failsafe mechanism to reinforce silencing. Major classes genes similar profiles, whether they are active or not. Our results suggest similar, DNA does not play significant role regulating many important for
