| 摘 要： | 遍布全球的赤潮问题近几十年来在我国海域愈演愈烈,成为我国海域最突出的生态灾害之一,严重威胁人类健康、生态安全和社会经济发展。随着研究的深入,我国海域越来越多的赤潮物种及隐存种得到鉴定,分类地位也经过不断修订,但是这些信息零散,不利于研究者系统认识和跟踪研究我国海洋赤潮物种。为此,文章整理了国内外赤潮物种研究资料,并参照联合国教科文组织全球有害藻华物种分类参考名单(2021年版,仅包括有毒赤潮物种)内容,完成了赤潮物种统计,共收录了341个赤潮物种,既包括有毒赤潮物种,也包括无毒赤潮物种。在这341个赤潮物种中,大部分(215种)在中国海域也得到鉴定,其中76个物种在所有主要海域都得到鉴定。近年来,基于通用分子标记(比如18S rDNA序列)的宏条形码分析被广泛应用于针对赤潮物种的鉴定和研究,成为研究赤潮物种组成及其时空动态变化的重要手段。然而,这341个赤潮物种中近30%的物种其18SrDNA序列尚未得到解析,严重限制了宏条形码方法的充分应用,是推行宏条形码分析中的重要瓶颈。全面构建赤潮物种分子标记可以促进宏条形码分析方法作为新一代海域生态调查分析技术,更好地将其应用于解析我国海域赤潮...

| Abstract: | In recent decades, the global harmful algal bloom (HAB) has become one of the most prominent ecological issues in Chinese sea areas, which seriously threatens human health, ecological safety, and social and economic development. At present, more and more HAB species and many cryptic species have been identified, and their classification status revised. However, scientific data of these HAB species are scattered, which is not conducive to our full understanding and tracking of HAB species in Chinese sea areas. In this study, we collected the HAB data globally in reference to IOC-UNESCO (version 2021). Of the total 341 HAB species recorded (including toxic and non-toxic), 215 species were identified in Chinese maritime waters and 76 species were identified in all major sea areas. Moreover, metabarcoding analysis based on universal molecular markers (such as 18S rDNA sequence) has been widely used for the identification and study of HAB species in terms of the species composition and temporal and spatial dynamics of HABs. However, about 30% of the 341 HAB species have not been molecular analyzed, which has seriously limited the application of metabarcoding method and metabarcoding analysis. Therefore, the construction of molecular markers for all HAB species will promote metabarcoding analysis into the next-generation technology, help analyze the diversity and spatio-temporal dynamics of HAB species in Chinese sea areas, and acceralate the study of HABs to a new level. |
