Global N6-Methyladenosine Profiling Revealed the Tissue-Specific Epitranscriptomic Regulation of Rice Responses to Salt Stress.

ABSTRACT: N6-methyladenosine (m6A) methylation represents a new layer of the epitranscriptomic regulation of plant development and growth. However, the effects of m6A on rice responses to environmental stimuli remain unclear. In this study, we performed a methylated-RNA immunoprecipitation sequencing analysis and compared the changes in m6A methylation and gene expression in rice under salt stress conditions. Salt stress significantly increased the m6A methylation in the shoots (p value < 0.05). Additionally, 2537 and 2304 differential m6A sites within 2134 and 1997 genes were identified in the shoots and roots, respectively, under salt stress and control conditions. These differential m6A sites were largely regulated in a tissue-specific manner. A unique set of genes encoding transcription factors,
