Deoxyribonucleic acid methylation and gene transcription have been proved as two underlying mechanisms involved in rapid plastic response to environmental stresses. However, it remains elusive on how DNA regulates under acute recurring challenges form the stress memory, further contributing invasion success during range expansions. Using a model invasive species Ciona robusta , we investigated regulatory roles of their contribution formation memory at 30 genes osmotic simulated process. We found bimodal distribution level for 68 mCpGs identified across all after challenges, but only five sites were significantly correlated with expression corresponding genes. These participated biological processes Ca 2+ transport metabolism lipid proline. At level, early-responding four tardy-responding these functionally related biosynthesis proline, lipid, taurine . transcriptional three ions, regulation water channels, taurine, lipid. Altogether, findings here suggest that should work concert facilitate thus improving performance invaders invasions.
