红海是研究气候变化下的珊瑚礁的合适模型,因为其强大的环境梯度为未来的全球变暖情景提供了一个窗口。例如,红海南部的珊瑚在本世纪末其他生物地理区域预计会出现的温度下茁壮成长。红海中的珊瑚在纬度梯度的热和环境条件下茁壮成长。因为与珊瑚相关的微生物群落有助于宿主生理学,我们对红海珊瑚相关细菌的已知多样性进行了系统评价,考虑地理位置和寄主物种。我们的评估包括对67种珊瑚宿主物种的54项研究,这些研究采用了依赖种植和独立种植的技术。大多数研究是在红海中部和北部进行的,而南部和西部地区大部分仍未开发。我们的数据还显示,尽管红海的珊瑚种类繁多,研究最多的珊瑚是疣孢霉,Dipsastraeaspp.,颗粒胸膜,和石竹。微生物多样性主要由来自γ变形细菌类的细菌,而最常见的细菌家族包括红杆菌科和弧菌科。我们还确定了与每个研究的珊瑚目相关的细菌家族:巩膜(n=125),Alcyonacea(n=7),和Capitata(n=2)。这篇综述涵盖了红海20年的研究,提供珊瑚相关细菌多样性的基线纲要。
The Red Sea is a suitable model for studying coral reefs under climate change due to its strong environmental gradient that provides a window into future global warming scenarios. For instance, corals in the southern Red Sea thrive at temperatures predicted to occur at the end of the century in other biogeographic regions. Corals in the Red Sea thrive under contrasting thermal and environmental regimes along their latitudinal gradient. Because microbial communities associated with corals contribute to host physiology, we conducted a systematic
review of the known diversity of Red Sea coral-associated bacteria, considering geographic location and host species. Our assessment comprises 54 studies of 67 coral host species employing cultivation-dependent and cultivation-independent techniques. Most studies have been conducted in the central and northern Red Sea, while the southern and western regions remain largely unexplored. Our data also show that, despite the high diversity of corals in the Red Sea, the most studied corals were Pocillopora verrucosa, Dipsastraea spp., Pleuractis granulosa, and Stylophora pistillata. Microbial diversity was dominated by bacteria from the class Gammaproteobacteria, while the most frequently occurring bacterial families included Rhodobacteraceae and Vibrionaceae. We also identified bacterial families exclusively associated with each of the studied coral orders: Scleractinia (n = 125), Alcyonacea (n = 7), and Capitata (n = 2). This
review encompasses 20 years of research in the Red Sea, providing a baseline compendium for coral-associated bacterial diversity.
