Project description:In this study, we attempt to characterize the transcriptomic profile of the Asian seabass gonads at various developmental stages. The protandric Asian seabass or barramundi (Lates calcarifer) typically matures as a male at approximately 2–4 years of age and then changes sex to a female in later years. For this experiment, Asian seabass of several ages were collected from the Marine Aquaculture Center of the Agri-Food & Veterinary Authority of Singapore and from farms around Singapore. There were no treatments carried out in this experiment. The gonads were examined by histology and classified according to sexual maturation status as described by Guiguen and colleagues (Guiguen et al. Environmental Biology of Fishes, 1994). Altogether, we analyzed 22 gonadal samples that could be classified into six different types of gonads.

Project description:In this study, we attempt to characterize the transcriptomic profile of the Asian seabass brains collected from the male and female sexes. The objective is to identify genes that show sexually dimorphic expression in the brain of this species. For this experiment, Asian seabass were collected from the Marine Aquaculture Center of the Agri-Food & Veterinary Authority of Singapore. There were no treatments carried out in this experiment. Four brains from adult male seabass (5 years old) with M3-type testis and four brains from adult female seabass (5 years old) with F3-type ovaries were used in this experiment. (Gonads were examined by histology and classified according to sexual maturation status as described by Guiguen and colleagues (Guiguen et al. Environmental Biology of Fishes, 1994)).

Project description:Purpose: sRNA-sequencing of mature and intermediate gonadal tissue in order to identify the differential expression of miRNAs during male to female (i.e. protandrous) sex transition Methods: Total RNA was extracted and sRNA was purified. cDNA libraries were constructed using a high definition adapter protocol (Xu et al. 2015). 50 bp sequencing was performed on Illumina's HiSeq 2500 at the Earlham Institute, Norwich, UK. Sequenced data was trimmed for adapters and filtered to remove very short and low complexity sequences. miRBase animal miRNA precursor sequences were mapped against the Asian seabass genome in order to generate a set of putative miRNA precursors. Putative precursor molecules with aligning mature miRBase miRNA(s) and forming a valid pre-miRNA hairpin structure were annotated as valid precursor miRNAs. Novel precursor and mature miRNAs were annotated using a combination of published algorithms and manual checking to ensure consistency with canonical miRNA biogenesis criteria. The alignment of sequenced reads against a non-redundant miRNA precursor set was used to determine raw read counts of mature miRNAs. Differential expression analysis was performed in order to identify differentially expressed mature miRNAs between conditions. Results: We detect 156, 71, 122, 151, 171 and 155 differentially expressed miRNA for the testis -> T1/T2, T1/T2 -> T3/T4, T3/T4 -> ovary, testis -> T3/T4, T1/T2 -> ovary and the testis->ovary comparisons respectively Conclusions: There is substantial differential expression of miRNAs at every stage of gonadal change in the Asian seabass during the sex transition process
