Project description:The present study identified and characterized miRNAs, which may play a major role in stress resistance. we applied high-throughput sequencing to investigate the alterations of miRNAs expression of sea cucumber under hypoxia stress(DO2_1,DO2_2,DO2_3),slight hypoxia stress(DO4_1,DO4_2,DO4_3) and normal condition(DO8_1,DO8_2,DO8_3). These results will provide a basis for future studies of miRNA regulation in sea cucumbers under hypoxia stress.
Project description:The proteomic profile of sea cucumber was conducted to identify key proteins involved in stress resistance based on the iTRAQ technique, including heat, hypoxia and heat plus hypoxia stress.
Project description:BackgroundThe diversity of the sedimentary environment and molluscs is rich in the intertidal zone of the Yellow Sea and Bohai Sea. At present, many of the investigations focus on macromolluscs, while the diversity of micromolluscs is seriously underestimated.New informationIn this study, the survey of micromolluscs was carried out in the intertidal zone of the Yellow Sea and Bohai Sea. The collection and preservation of micromolluscs, as well as the preparation methods of morphological characteristic structures by scanning electron microscopy (SEM) were explored. A total of 20 species were described in this survey. These can be assigned to 16 families, four orders (Vetigastropoda (1), Caenogastropoda (10), Heterobranchia (5) and Autobranchia (3)) and two classes (Gastropoda (17), Bivalvia (3)).
