ROS1 promotes low temperature-induced anthocyanin accumulation in apple by demethylating the promoter of anthocyanin-associated genes.

ABSTRACT: Low temperature can affect the growth and development of plants through changes in DNA demethylation patterns. Another known effect of low temperature is the accumulation of anthocyanin pigments. However, it is not known whether the two phenomena are linked, specifically, whether DNA demethylation participates in anthocyanin accumulation in response to low-temperature stress. The ROS1 gene is involved in plant DNA demethylation and influences methylation levels in response to low temperature stress. In this study, using RNA sequencing, we detected that the transcription levels of MdROS1 correlate with the anthocyanin content, as well as with those of anthocyanin biosynthesis-related genes in apple (Malus domestica), at low temperatures. Genomic bisulfite sequencing showed that the methylat
