Male and Female DNA and RNA sequencing in several nematode species

ABSTRACT: The overall goal of this investigation was to investigate X-content of sex-biased genes in several nematode species. The following species of nematode were investigated: *C. elegans, *N2; *C. brenneri, *PB2801; *C. briggsae, *AF16; *C. remanei*, PB4641; *P. **pacificus, *PS312*.* Genomic DNA sequencing data was used to assign X and autosomal - linkage to unassembled sequencing contigs. Male and female RNA seq data was then generated and used to determine sex-biased expression. For both DNA and RNA experiments, 50bp paired-end (DNA) or single-end (RNA) reads were generated on the Illumina HiSeq 2500. Sequencing lanes were multiplexed. Genomic DNA was isolated from 50-100 hand-picked young adult worms. At least two replicates for each sex were prepared. DNA was sheared via sonication and 350-500 bp sequencing libraries were prepared following the Illumina protocol. Total RNA was isolated from at least 1000 hand-picked L4/young adult worms (*C. **elegans, *N2) or J4/young adult worms (*P. pacificus, *PS312*). *PolyA beads were used to enrich for mRNA. Stranded RNAseq libraries were prepared via incorporation of dUTPs during cDNA synthesis, following the protocol detailed in Parkhomchuk et al, 2009. DNAseq and RNAseq reads were aligned to the appropriate WS228 reference genomes.

DNAseq and RNAseq reads were aligned to the appropriate WS228 reference genomes. DNA sequencing data (2-3 replicates) from male and female YA worms are included along with RNAseq data from C.elegans YA hermaphrodites and P.pacificus YA males and hermaphrodites.

P. pacificus young adults: Exposed to Bacillus thuringiensis DB27 versus exposed to E. coli OP50 : 4 hours

Project description:Transcriptional profiling of P. pacificus young adult worms exposed to pathogen Xenorhabdus nematophila for 4 hours versus age-matched worms exposed to control lab food E. coli OP50. The goal was to identify genes regulated in response to pathogen. The broader goal of study was to study evolution of pathogen response by comparing this expression profile to that obtained by exposing the nematode C. elegans to the same pathogen. Other experiments which are a part of this study include expression profiling of C. elegans and P. pacificus on other pathogens including Staphylococcus aureus, Serratia marcescens and Xenorhabdus nematophila. One-condition experiments. P. pacificus young adults: Exposed to Bacillus thuringiensis DB27 versus exposed to E. coli OP50 : 4 hours. 4 biological replicates for each condition, including 2 dye-swaps.
