“…A methylation indicator, the presence of oxidative stress, has been shown to increase DNMT expression in plants. In in vitro grown birch plants, increased ROS activity in older calli elevated DNA methylation and was accompanied by an increased expression of DNMT genes such as domain rearranged methyltransferase (DRM), methyltransferase (MET) and chromomethylase (CMT) [56] .…”

“…S5), which mainly represses the jumping of the transposon to maintain the stability of the genome (Zhang et al 2006). The distribution pattern of genomic features revealed that the repetitive sequence, such as TEs, was spread uniformly across the entire birch genome relative to Arabidopsis thaliana (Zeng et al 2015). In Arabidopsis, the transposon ratio is less than 15% and is mainly enriched in the centromere's heterochromatic regions.…”

The Betula genus contains pentacyclic triterpenoid betulin known for its environmental adaptation and medicinal properties. However, the mechanisms underlying betulin biosynthesis responding to climate change remain unclear. In this study, the role of epigenetic modification (DNA methylation) in betulin biosynthesis was examined and how climatic factors influence it. Whole-genome bisulfite sequencing was performed for greenhouse-grown Chinese white birch (Betula platyphylla Sukaczev) treated with DNA methylation inhibitor zebularine (ZEB) and a natural birch population in Northeast China. ZEB treatment significantly affected the CHH methylation level of transposable elements and betulin content in a hormesis dose-dependent manner. The methylation and expression of bHLH9, a key transcriptional factor controlling betulin biosynthesis, were also consistently affected by ZEB treatment as a hormetic dose–response. In the natural population, there was a positive correlation between promoter methylation of bHLH9 and summer precipitation, while winter temperature was negatively correlated. Thus climate-dependent methylation of bHLH9 regulates the expression of downstream genes involved in betulin biosynthesis. This study highlights the role of environmental signals to induce epigenetic changes that result in betulin production, possibly helping to develop resilient plants to combat ongoing climate change and enhance secondary metabolite production.
