Genome-wide analysis of DNA methylation in photoperiod- and thermo-sensitive male sterile rice Peiai 64S.

ABSTRACT:

Background

Epigenetic modifications play important roles in the regulation of plant development. DNA methylation is an important epigenetic modification that dynamically regulates gene expression during developmental processes. However, little studies have been reported about the methylation profiles of photoperiod- and thermo-sensitive genic male sterile (PTGMS) rice during the fertility transition.

Results

In this study, using methylated DNA immunoprecipitation sequencing (MeDIP-seq), the global DNA methylation patterns were compared in the rice PTGMS line PA64S under two different environments (different temperatures and day lengths). The profiling of the DNA methylation under two different phenotypes (sterility and fertility) revealed that hypermethylation was observed i
