Project description:DNA methylation in wild type bolting plants, wild type seedlings, and ddm1 seedlings. The purpose of the McrBC methylation microarray assay is to determine which regions of a genome are methylated versus those that are unmethylated in a single Arabidopsis thanliana genotype. McrBC is a methylation-sensitive enzyme that restricts DNA only at purine-Cmethyl half sites when separated between 50bp and 3kb. A designated amount of DNA from a particular genotype is sheared to a size range of 1kb-10kb using nebulization. We restrict half of the nebulized DNA with McrBC, and the methylated fraction is then removed from the unmethylated fraction through gel purification of DNA fragments greater than 1kb.* The remaining nebulized DNA is subjected to the same gel purification scheme, but with no McrBC treatment. In a single hybridization, the untreated sample is labeled with Cy5 and the McrBC-treated sample with Cy3. Thus, after labeling and microarray hybridization, the ratio of normalized Cy5 to normalized Cy3 represents the relative methylation at the sequence represented by the spot on the microarray. Dye swap analysis is carried out to take account of experimental variation by repeating the hybridization with identical samples labeled with Cy3 and Cy5, respectively.

Project description:N6-methyladenosine (m6A) is a crucial epigenetic modification in mRNA and the most abundant methylation in eukaryotes. However, research on m6A modification in radish (Raphanus sativus) is not as extensive as in model plants. In this study, we analyzed m6A modification during the vegetative and reproductive growth stages of radish using m6A-seq and RNA-seq to explore its potential role in bolting and flowering. The results showed that m6A peaks significantly increased during the reproductive growth stage compared to the vegetative stage, with more m6A modification sites in the stop codon, 3' UTR, and promoter regions. Overexpression of the RsALKBH10B gene led to a global reduction in m6A modification and resulted in an early bolting and flowering phenotype, with transcription levels of key flowering factors RsSOC1 and RsFT increasing by 10-40 fold. Correlation analysis between differential m6A modification and differentially expressed genes indicated that genes such as RsSUF4, RsAGL13, and RsCDF5 might regulate bolting and flowering. Overexpression of RsSUF4 delayed bolting and flowering and decreased overall m6A modification levels; in positive transgenic plants, higher m6A levels of RsSUF4 were associated with lower transcription levels. These findings suggest that m6A methylation may regulate gene expression related to bolting and flowering in radish by affecting mRNA stability, ultimately leading to bolting and flowering.
