SRY-related HMG box (Sox) genes are characterized by the presence of a DNA-binding HMG domain and involved in a diverse range of developmental processes.In this study,we identified a novel Sox gene,de
青蟹是世界性的经济养殖蟹类之一。近年来青蟹健康养殖面临两大问题：①种质资源衰退：随着捕捞强度的加大和海域环境的污染，青蟹野生群体面临种质退化和遗传多样性丧失的风险；②缺乏优良品种：养殖青蟹苗种主要来自天然海域，未经过遗传改良，青蟹已出现抗逆性、抗病力和生长率下降等现象。有鉴于此，本项目围绕青蟹种质资源保护和遗传改良这两个核心问题开展了以下四个方面的研究：(1)我国青蟹属种类组成；(2)拟穴青蟹种群
我国海水虾蟹养殖面积达305,584公顷,产量1,433,763吨(2015年中国渔业统计年鉴)。根据对虾病害的生物防控原理,筛选半滑舌鳎、三疣梭子蟹等能够有效摄食病弱死虾、控制对虾病原传播,且具有较高经济价值的物种,通过合理搭配不同的养殖密度和规格,建立对虾池塘多营养层次生态养殖技术。系统分析了不同生态养殖系统中的水质理化指标、养殖水体和池塘底泥中营养盐、微生物种群的变化、氮磷收支规律等,提出了
In vertebrates,bone morphogenetic proteins (BMPs) play an important role in various biological processes.However,the function of BMPs in crustaceans is still unknown.In our study,a ligand (BMP7) and t
In many organisms vasa gene is specifically expressed in germ line cells throughout the life cycle,making it a powerful molecular marker to study germ line development.Recent evidence indicates that f
In crustaceans,periodic shedding of the exoskeleton is one of the most important physiological process which is essential for crustacean muscle growth and postembryonic development.Myosins are express
Chaperonin containing the T-complex polypeptide-1 (CCT),which is known to be involved in intracellular assembly and folding of proteins,is a class of chaperonin omnipresent in all forms of life.Previo
