Benthic foraminifera are one of the major groups of marine protists that also occur in freshwater and terrestrial habitats. They are widely used to monitor current and past environmental conditions. Over the last three decades, thousands of DNA sequences have been obtained from benthic foraminiferal isolates. The results of this long-term effort are compiled here in the form of the first curated benthic foraminiferal ribosomal reference dataset (BFR2). The present dataset contains over 5000 sequences of a fragment of the 18S rDNA gene, which is recognized as the DNA barcode of foraminifera. The sequences represent 279 species and 204 genera belonging to 91 families. Thirteen percent of these sequences have not been assigned to any morphologically described group and may represent species new to science. Furthermore, forty-five percent of the sequences have not been previously published. The BFR dataset aims to collect all DNA barcodes of benthic foraminifera and to provide a much-needed reference dataset for the rapidly developing field of molecular foraminiferal studies.
底栖有孔虫是海洋原生生物的主要类群之一，也存在于淡水和陆地生境中。它们被广泛用于监测当前和过去的环境条件。在过去的三十年中，已经从底栖有孔虫分离物中获得了数千个 DNA 序列。本长期努力的结果以第一个经过精心整理的底栖有孔虫核糖体参考数据集（BFR2）的形式汇集在这里。本数据集包含超过 5000 个 18S rDNA 基因片段的序列，该片段被认为是有孔虫的 DNA 条码。这些序列代表了 279 个种和 204 个属，属于 91 个科。其中 13%的序列尚未被分配到任何形态描述的群体中，可能代表了科学界新的物种。此外，45%的序列以前没有发表过。BFR 数据集旨在收集所有底栖有孔虫的 DNA 条码，并为分子有孔虫研究这一快速发展的领域提供急需的参考数据集。
