In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Studies on the role of PGE2 in the reproduction of Small Abalone,Haliotis diversicolor [PDF]
杂色鲍(Haliotisdiversicolor),又称九孔鲍,是我国福建南部和广东等沿海地区鲍养殖的重要品种,商业价值较高,杂色鲍繁殖调控对于其人工育苗和育种都有重要意义,但目前有关鲍的繁殖分子机制研究却十分有限,尤其是对鲍的产卵和排精机制了解更少。本文通过组织学、分子生物学和生物化学方法对杂色鲍的前列腺素E2(PGE2)、PGE2合成相关的三种酶基因和EP4受体进行了研究,并结合生态实验讨论了PGE2在杂色鲍繁殖中的作用。主要结果如下: 1.PGE2在杂色鲍繁殖中功能研究 ...

How much biotic nativeness matters across human demographic groups
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

The impacts of coastal defense structures on rocky intertidal community in Yangtze River Delta [PDF]
长江三角洲是长江、黄河以及在此区域的其他河流的活动形成的冲积平原。末次冰期(LastGlacialMaximum,LGM)以后的一万年以来,长江三角洲在海陆交互作用的影响下逐渐扩展。位于长江三角洲地带的近900km的江苏沿岸海岸线除约40km的基岩海岸以外,均为不适宜岩相潮间带生物大量聚集的淤泥质平原海岸。近年来随着中国沿海经济的飞速发展,对土地需求的不断增加,越来越多的沿岸防护建筑正在被修建,成为我国沿岸的“海上长城”。这些沿岸防护建筑显著改变了江苏沿岸的滩涂景观,可能对潮间带群落造成严重影响 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Genetic mapping and quantitative trait loci analysis of growth-related traits in the small abalone Haliotis diversicolor using next-generation sequencing [PDF]
杂色鲍(Haliotisdiversicolor)广泛分布于韩国、日本、中国、越南和菲利宾沿岸,是一种具有重要经济价值的养殖鲍种。应用传统的育种方式,杂色鲍育种工作虽然已经取得了一定进展,但是开展分子标记辅助选育仍然是加速该进程的必然选择。下一代测序技术可以高通量、低成本地完成SNP标记的发掘与分型,目前已被广泛应用于遗传研究的各个方面。本文利用下一代测序技术完成了杂色鲍的SNP标记开发与验证、高密度连锁图谱构建、QTL定位和候选基因的关联分析等工作。主要结果如下: (1) 杂色鲍高密度连锁图谱的构建 ...

Genetic diversity on the Genus Skeletonema (Bacillariophyceae) in the coastal waters of China [PDF]
骨条藻(Skeletonema)是一类广泛分布于沿海水域的浮游硅藻,也是常见的赤潮生物。目前,对于整个中国沿海骨条藻的分类和分子生物学方面的研究,比较分散,还不能很好地回答我国沿海骨条藻的种类多样性和遗传多样性的问题。因此,本文选择我国沿海的代表性海区,进行周年采样,对分离培养的纯种株系,选择核糖体LSUnrDNA和ITS片段(5.8SrDNA及转录间隔区ITS1、ITS2)对其进行遗传多样性及系统进化分析,旨在从分子生物学方面分析我国沿海骨条藻属的种内、种间和地理株系间的差异,以及系统进化关系 ...
