摘要: Background Epigenetic regulation is well recognized for its importance in gene expression organisms. DNA methylation, an important epigenetic mark, has received enormous attention recent years as it’s a key player many biological processes. It remains unclear how methylation contributes to transcription maize seeds. Here, we take advantage of technologies examine the genome-wide association with four types sequences, including protein-coding genes, pseudogenes, transposable elements, and repeats embryo endosperm, respectively. Results The CG, CHG CHH contexts plays different roles control expression. Methylation around start sites stop regions genes negatively correlated, but bodies positively level. The upstream are enriched 24-nt siRNAs contain high levels which correlated analysis sequence content within CHG, or reveals that only affected by local from Arabidopsis. Conclusions In summary, conclude methylation-regulated varies parts specific seeds differs other plant species. Our study helps people better understand viewpoint transcriptional controlled one factors influencing transcription, associated small RNAs.
