MeDIP-seq of two phytophthora species at mycelium stage

We report the 6mA methylation profiling in two Phytophthora species and one psdamt3 mutant. Genomic DNA of Phytophthora sojae P6497 mycelium (3-days old), Phytophthora infestans T30-4 mycelium and psdamt3 mutant T9 (lost 374bp by CRISPR/Cas9) was extracted and sonicated to 200-400bp using Biorupter UCD-600. The antibody sysy 202003 was used to immunoprecipitation. We find that 6mA is associated with lowly expressed genes in two Phytophthora species. 6mA methylome is preferentially associated with TEs, the genes and intergenic regions that form the gene-sparse compartments of Phytophthora genomes. In the psdamt3 mutant, 6mA level reduced in TEs and illustrates the uneven reduction pattern around the TSS. Examination of N6-methyladenine in two phytophthora species
