报告内容:
Enzymatic DNA methylation comes in three main varieties, as as 5-methylcytosine, 4-methylcytosine, and 6-methyladenine. In the first part of my talk, I will report crystallographic and bioinformatic data on how DNA methylation is sensed by proteins, both negatively and positively. I will show that there is a small modular toolkit for this task, and that cytosine and adenine methylation are detected rather differently. In the second part of my talk, I will describe our efforts to characterize maintenance of DNA methylation in a model organism, the plant A. thaliana, by bisulfite conversion and reversible terminator (Illumina) sequencing, and by Nanopore sequencing. The data indicate strong long range correlations in methylation of a single DNA molecule, and provide evidence for crosstalk between different methylation types (CpG, CHG, CHH).
