Abstract This review article explores the state of DNA barcoding of macroalgae in the Mediterranean Sea. Data from the Barcode of Life Data System (BOLD) were utilised in conjunction with a thorough bibliographic review. Our findings indicate that from around 1124 records of algae in the Mediterranean Sea, only 114 species have been barcoded. We thus conclude that there are insufficient macroalgal genetic data from the Mediterranean and that this area would greatly benefit from studies involving DNA barcoding. Such research would contribute to resolving numerous questions about macroalgal systematics in the area and address queries related to biogeography, especially those concerned with non-indigenous species. It could also possibly result in the development and application of better, cost-effective biodiversity monitoring programmes emanating from UN conventions and EU Directives. One possible way of achieving this is to construct DNA libraries via sequencing and barcoding, subsequently enabling better cost-effective biodiversity monitoring through environmental DNA metabarcoding.

地中海大型藻类 DNA 条形码的现状：目前缺乏但迫切需要

摘要 这篇综述文章探讨了地中海大型藻类的 DNA 条形码状态。来自生命条码数据系统 (BOLD) 的数据与彻底的书目审查结合使用。我们的研究结果表明，从地中海中大约 1124 条藻类记录中，只有 114 种藻类被编码。因此，我们得出结论，地中海的大型藻类遗传数据不足，该地区将从涉及 DNA 条形码的研究中受益匪浅。此类研究将有助于解决有关该地区大型藻类系统学的众多问题，并解决与生物地理学相关的问题，尤其是与非本土物种有关的问题。它还可能导致更好的开发和应用，源自联合国公约和欧盟指令的具有成本效益的生物多样性监测计划。实现这一目标的一种可能方法是通过测序和条形码构建 DNA 文库，随后通过环境 DNA 元条形码实现更具成本效益的生物多样性监测。
