In plants, 5mCs can happen in three sequence contexts as CpG, CHG, and CHH. Although long nanopore sequencing reads are advantageous in the detection of 5mCs, existing methods can only detect 5mCs in the CpG context. Here, we develop a deep learning tool to detect genome-wide 5mCs of all three contexts in plants from nanopore reads. We develop a denoising process to enable DeepSignal-plant to achieve high correlations with bisulfite sequencing for 5mC detection in all three contexts. Furthermore, DeepSignal-plant can profile more 5mC sites, which will help to provide a more complete understanding of epigenetic mechanisms of different biological processes.
