The association of TEs and cis-regulatory modules (CRMs)
To
clarify the evolutionary relationship between TEs and CRMs, the
genome-wide CRMs were predicted.
By
comparing the location information of CRMs to TEs, we found that there
were 3.7% ~ 16.9% of TEs highly overlapped with CRMs
in location in each species (Table 1). KEGG enrichment analysis was
performed on the gene function near CRMs that overlapped with TEs. The
results showed that the pathways enriched in most species were still
involved in environment information processing, such as Circadian
entrainment (map 04713), cAMP signaling pathway (map 04024), and
Glutamatergic synapse (map 04724) (Table S5). These enrichment results
were highly
similar
to the results presented in above section.
