摘要

由于小球藻类微藻形态简单，表型可塑性高，因此很难正确识别其种类。分子工具的使用彻底改变了对藻类多样性的研究，使许多新分类群的发现取得了进展。本文介绍了从俄罗斯联邦萨马拉地区的普鲁多维科夫淡水湖新近分离的菌株的研究结果。这些菌株具有典型的小球藻形态，具有球形细胞和杯状的顶叶叶绿体。叶绿体含有一个被淀粉粒包裹的类核蛋白。然而，18S-ITS1-5.8S-ITS2序列分析表明，所研究的菌株与Micractinium属密切相关。基于形态学、分子和环境特征的比较分析(采用多相法)，我们认为它们是micractinum的新种:micractinum kostikovii sp. nov。

New species Micractinium kostikovii (Chlorellaceae, Trebouxiophyceae) from Russia

Correctly identifying species of Chlorella‐like microalgae is difficult because of their morphological simplicity and high phenotypic plasticity. The use of molecular tools has revolutionized research on algal diversity, enabling such advances as the discovery of numerous new taxa. This article presents the results of a study of strains that are newly isolated from a freshwater Lake Prudovikov (Samara region, Russian Federation). These strains had the typical Chlorella morphology, exhibiting spherical cells and a cup‐shaped parietal chloroplast. The chloroplast contained a single pyrenoid enveloped by starch grains. However, 18S–ITS1–5.8S–ITS2 sequence analyses indicated that the studied strains are strongly allied with the well‐supported genus Micractinium. Based on the results of a comparative analysis of the morphological, molecular and environmental characteristics of the studied strains (employing a polyphasic approach), we propose that they are new species of Micractinium: Micractinium kostikovii sp. nov.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
