(Submitter supplied) Centromeres are chromosomal regions that serve as platforms for kinetochore assembly and spindle attachments, ensuring accurate chromosome segregation during cell division. Despite functional conservation, centromeric sequences are diverse and usually repetitive across species, making them challenging to assemble and identify. Here, we describe centromeres in the model oomycete Phytophthora sojae by combining long-read sequencing-based genome assembly and chromatin immunoprecipitation for the centromeric histone CENP-A followed by high-throughput sequencing (ChIP-seq). more...

(Submitter supplied) Purpose and methods:Transcriptome profiling of Phytophthora sojae pssu(z)12 mutant T34 (lost 561bp by CRISPR/Cas9) mycelium (3-days old) were generated to find out the relationship between H3K27me3 and gene expression on Avr1b locus. Wild-type P. sojae P6497 was took as a comparative control. RNA-seq data was mapped using Tophat2, and gene expression data was generated by Cufflinks. Transcriptome profiles were displayed using IGV browser.

(Submitter supplied) We report the H3K27me3 profile on Avr1b locus in two Phytophthora sojae strains P6497 and pssu(z)12 mutant. Nuclei of Phytophthora sojae P6497 and pssu(z)12 mutant T34 (lost 561bp by CRISPR/Cas9) mycelium (3-days old) was extracted and digested to 200-400bp using micrococcal nuclease (MNase: NEB M0247S). The antibody Millipore 07-449 was used to immunoprecipitation. We find significant accumulation of H3K27me3 at Avr1b locus in Avr1b silencing strain P6497 and clear H3K27me3 depletion at Avr1b locus in Avr1b unsilenced strain pssu(z)12 mutant T34.

(Submitter supplied) Purpose and methods:Transcriptome profiling of Phytophthora sojae P6497 mycelium (3-days old) and Phytophthora infestans T30-4 mycelium (6-days old) were generated to find out the relationship between 6mA methylation and gene expression. RNA-seq data was mapped using Tophat2, and gene expression data was generated by Cufflinks. Transcriptome profiling of P. sojae psdamt3 mutant T9 (lost 374bp by CRISPR/Cas9) was generated to check the differential expressed genes (DEGs) between the mutant and wild-type P. more...

(Submitter supplied) 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. more...
