Project description:To investigate genome-wide R-loops during meiosis exit and R-loop profiles changes with Nkapl knockout, we employed ssDRIP-seq (single-strand DNA ligation-based library preparation after DNA:RNA hybrid immunoprecipitation by S9.6 and sequencing) in wild-type and Nkapl-KO testes at P21.
Project description:The R-loop is a common chromatin feature presented from prokaryotic to eukaryotic genomes and has been revealed to be involved in multiple cellular processes and associated with many human diseases. Here, we take the advantage of our recently developed ssDRIP-seq method to profile genome-wide R-loop levels of soybean (Glycine max).

Here, we take the advantage of our recently developed ssDRIP-seq method to profile genome-wide R-loop levels and provided a first-hand R-loop atlas of Rice (Oryza sativa) at different developmental stages.

Here, we take the advantage of our recently developed ssDRIP method to profile genome-wide R-loop levels and provided a first-hand R-loop atlas during Arabidopsis development and in response to various environmental factors.
Project description:The R-loop is a common chromatin feature presented from prokaryotic to eukaryotic genomes and has been revealed to be involved in multiple cellular processes. Here, we developed a novel R-loop profiling technique, ULI-ssDRIP-seq, to decte global R-loops from a limited number of cells. Based on this method, we profiled the R-loop landscapes during parental-to-zygotic transition and early development regulatory in zebrafish, and revealed a series of important characters of R-loops.
Project description:High-order rice chromatin contains numerous interactions among DNA, RNA and protein to regulate critical biological processes in various aspects of rice life. We developed an effective method for mapping histone-mediated chromatin associated RNA-DNA interactions, followed by paired-end-tag sequencing (ChRD-PET) in rice. With H3K4me3 ChRD-PET, H3 ChRD-PET and RNase H treated H3K4me3 ChRD-PET, we present a highly comprehensive map of RNA and chromatin interactions around promoters in rice MH63. Through integrating ChIA-PET (published data), ChRD-PET and ssDRIP-seq data analysis, we demonstrated the function of RNAs-chromatin interactions in different level. We also conducted ATAC-seq and integrative analysis uncovered the relationship of epigenetic modifications and ChRD-PET interactions. Our findings firstly revealed the map and features of RNAs-chromatin interactions in rice.
