Project description:The rice field eel (Monopterus albus) is an economically important freshwater-farmed fish with natural sex reversal characteristics, which results in low egg production and seedling shortage. Limited epigenomic and transcriptomic information during sex reversal hinders research on the reproductive development of Monopterus albus. In this investigation, 9 key stages during sex reversal were collected for multi-omics experiments, including PacBio Iso-seq, RNA-seq and ATAC-seq. Through combined analysis of Iso-seq and RNA-seq, we constructed more accurate transcript annotation than those from NCBI. A total of 37,911 unannotated transcripts were obtained, including transcripts from novel genes and alternative splicing structures, etc. The noteworthy point is that our annotations have more precise polyA locations. In addition, we identified multiple potential cis-regulatory elements with high confidence based on changes in chromatin accessibility by ATAC-seq, providing precise targets for regulating gene expression and thereby modulating gonadal development. In summary, we provides a comprehensive and convenient data resource for studying sex reversal-related mechanisms from multiple perspectives.

Project description:Sex chromosomes and more particularely the X chromosomes are known to have a major effect on hybrid male sterility. In this experiment by making use of the reciprocal hybrids between D. simulans and D. sechellia, we are showing the effect of these chromosomes on gene expression in male hybrids Keywords: X chromosome, hybrid

Project description:Gene expression was examined in testis and brain tissue between two species (Xenopus laevis and Xenopus borealis) and their hybrid. Genomic DNA hybridizations of the microarray target and non-target species were used to select probes that are unbiased between species.

Project description:To explore the aberrant expression patterns between hybrid sexes, we compare the global gene expression of 7-day-old whole body adults of hybrids by sex in recently diverged Drosophia pseudoobscura group 7-day-old virgin hybrid flies were assayed by sex. Reciprocal F1 hybrids were produced for D. pseudoobscura/D. persimilis and D. pseudoobscura/D. p. bogotana crosses by mass mating virgin flies. At least three isofemale inbred lines were used for each species (D. pseudoobscura; D. persimilis; D. pseudoobscura bogotana).Two separate labeling reactions per sample were pooled and hybridized to the Agilent single color (Cyanine 3-CTP dye) arrays. Three different replicates were hybridized for each hybrid and sex. Pure species data (collected the same time and deposited as GSE17192 ) and hybrid data were analyzed together to determine the misexpression differences between hybrid males and females.
