Comparative proteomics analysis of spermary and ovary in <i>Hyriopsis schlegelii</i>

<p>We provide the first large-scale quantitative proteomics analysis in <i>Hyriopsis schlegelii</i>. To investigate the proteins expressed in the gonads, a quantitative proteomics approach has been utilized to analyze differentially expressed proteins between the spermary and ovary. In this study, we identified and quantified 2416 proteins in the gonads of <i>Hyriopsis schlegelii</i>. Of these, 559 proteins showed significantly different expression between the spermary and ovary. Some specific proteins expressed in either the spermary or ovary were identified in <i>Hyriopsis schlegelii</i>. In addition, a series of proteins related to gametogenesis were also identified. Compared with previous reports, many proteins in <i>Hyriopsis schlegelii</i> identified here have different expression patterns between the spermary and ovary. The special hermaphroditism in <i>Hyriopsis schlegelii</i> may contribute to these inconsistent results. The provided proteomics data could be considered as a starting point for subsequent studies focusing on the proteins involved in sexual gland development and maturity.</p> <p>The distribution of 2416 proteins based on the differential expression between spermary and ovary.</p>
