We have analysed a centromeric satellite DNA family that is conserved in several commercial and non-commercial oyster species (Ostrea edulis, O. stentina, Crassostrea angulata, C. gigas, C. gasar, C. ariakensis, C. virginica and C. sikamea). This satellite DNA family is composed of AT-rich repeat sequences of 166+/-2 bp and presents a 9-bp motif similar to the mammalian CENP-B box. The homology...
Cupped oysters are common and abundant along the coast of China, but their classification has been uncertain. In previous studies, we classified 2 of the cupped oysters into 2 subspecies:Crassostrea gigas gigas from the northern coast of China and Crassostrea gigas angulata from the southern coast of China. There is another small cupped oyster that seems different from these 2 species and resem...
متالوتیونین پروتئینی با وزن مولکولی پایین و غنی از اسید آمینه سیستئین است که توانایی باند شدن با دامنه وسیعی از فلزات سنگین را دارد. در تحقیق حاضر، جداسازی، شناسایی و کلونینگ ژن متالوتیونین برای اولین بار از گونهcrassostrea sp. از آبهای خلیج فارس گزارش شده است. ژن متالوتیونین این صدف که تا پیش از این crassostrea gigas نامیده شده بود، دارای یک چارچوب خواندن باز 225 جفت بازی است که با کدون آغاز a...
Marine intertidal organisms commonly face hypoxic stress during low tide emersion; moreover, eutrophic conditions and sediment nearness could lead to hypoxic phenomena; it is indeed important to understand the molecular processes involved in the response to hypoxia. In this study the molecular response of the Pacific oyster Crassostrea gigas to prolonged hypoxia (2mg O(2) L(-1) for 20d) was inv...
Invasion trajectories of introduced alien species usually begin with a long establishment phase of low abundance, often followed by exponential expansion and subsequent adjustment phases. We review the first 26 years of feral Pacific oysters Crassostrea gigas around the island of Sylt in the Wadden Sea (North Sea, NE Atlantic), and reveal causal conditions for the invasion phases. Sea-based oys...
