ChIP-seq of phytophthora sojae P6497

Project description: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). P. sojae centromeres cluster at a single focus in the nucleus at different life stages and during nuclear division. We report a highly contiguous genome assembly of the P. sojae reference strain, which enabled identification of 15 highly enriched CENP-A binding regions as putative centromeres. By focusing on 10 intact regions, we demonstrate that centromeres in P. sojae are regional, spanning 211 to 356 kb. Most of these regions are transposon-rich, poorly transcribed, and lack the euchromatin mark H3K4me2 but are embedded within regions with the heterochromatin marks H3K9me3 and H3K27me3.

Digital gene expression profiling of the Phytophthora sojae transcriptome

Project description:This experiment contains Phytophthora sojae samples and RNA-seq data from experiment E-GEOD-29561 (https://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-29651/) to understand gene expression during the P. sojae life cycle. The transcriptome of the oomycete plant pathogen Phytophthora sojae was profiled at 5 different developmental stages: mycelia (MY), zoosporangia (SP), zoospores (ZO), cysts (CY) and germinating cysts (GC); based on a 3'-tag digital gene expression (DGE) protocol. More than 90 million clean sequence tags were generated and compared to the P. sojae genome and its 19,027 predicted genes. A total of 14,969 genes were detected, of which 10,044 were deemed reliable because they mapped to unambiguous tags. A web-based server named the Phytophthora Transcriptional Database (PTD) has been established.

H3K27me3 in Phytophthora sojae P6497 and its pssu(z)12 mutant at mycelium stage

Project description: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.

Transcriptomes of pssu(z)12 mutant from phytophthora sojae P6497 at mycelium stage

Project description: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.

Digital gene expression profiling of the Phytophthora sojae transcriptome

Project description:The transcriptome of the oomycete plant pathogen Phytophthora sojae was profiled at 10 different developmental and infection stages based on a 3'-tag digital gene expression (DGE) protocol. More than 90 million clean sequence tags were generated and compared to the P. sojae genome and its 19,027 predicted genes. A total of 14,969 genes were detected, of which 10,044 were deemed reliable because they mapped to unambiguous tags. A comparison of the whole-library genes expression patterns suggested four groups: 1) mycelia and zoosporangia (MY and SP); 2) zoospores and cysts (ZO and CY); 3) germinating cysts (GC); 4) five infection site libraries (IF1.5 to IF24h). The libraries from the different groups showed major transitional shifts in gene expression. From the ten libraries, 722 gene expression pattern clusters were obtained and the top 16 ones, containing more than half of the genes, comprised enriched genes with different functions including protein localization, triphosphate metabolism, signaling process, and non-coding RNA metabolism. An evaluation of the average expression level of 30 pathogenesis related gene families revealed that most were infection induced, but with diverse expression patterns and levels. A web-based server named the Phytophthora Transcriptional Database (PTD) has been established. The five axenically grown stages were mycelia (MY), zoosporangia (SP), zoospores (ZO), cysts (CY), and germinating cysts (GC). The five infection stages, 1.5, 3, 6, 12 and 24 h after inoculation onto susceptible soybean leaf tissues (IF1.5h to IF24h).
