During black raspberry (Rubus occidentalis) fruit ripening, promoter DNA methylation progressively decreases while CHG/CHH methylation increases in transposon-rich regions, reshaping transcriptional programs.
- Why it matters: Fruit ripening requires coordinated gene expression, metabolism, and epigenetic control, but how DNA methylation dynamics regulate transcription and metabolite buildup in black raspberry remained unclear.
- What they did: A developmental series of transcriptome, methylome, and metabolome profiling was integrated to map genome-wide and locus-specific methylation changes, including promoter versus transposon regions and CHG/CHH contexts.
- The result: Two methylation transitions—promoter hypomethylation and CHH hypermethylation—govern transcriptional shifts in ripening genes, and multi-omics links anthocyanin accumulation with coordinated biosynthetic and regulatory networks.
