Abstract

Two rare species, Chlamydomonas proteus and Xerochlorella minuta, were isolated from snow samples in sites of “algal blooms” in the Subpolar Urals and Western Sayan. As a result of the study of strains using light microscopy and molecular genetic methods (the nucleotide sequence analysis of 18S and ITS2 rDNA), new data on morphology, ecology and distribution of these species were obtained. The data expanded the species’ diagnostic characteristics. Chlamydomonas proteus is the first record on Russian territory supported by molecular studies.

乌拉尔次极地和西萨扬雪原两种罕见绿藻（叶绿体）的新记录

从乌拉尔次极地和西萨扬 "藻类孳生地 "的雪样中分离出了两个稀有物种，即 Chlamydomonas proteus 和 Xerochlorella minuta。通过使用光学显微镜和分子遗传学方法（18S 和 ITS2 rDNA 的核苷酸序列分析）对菌株进行研究，获得了有关这些物种的形态学、生态学和分布的新数据。这些数据扩大了该物种的诊断特征。蛋白衣藻（Chlamydomonas proteus）是俄罗斯境内第一个通过分子研究获得支持的记录。

期刊介绍： The Journal is one of the scientific periodicals of the Komarov Botanical Institute (at present belonging to the Russian Academy of Sciences), founded as the garden of medicinal plants by Peter the Great in February 1714. The Journal under the name Novosti sistematiki nizshikh rastenii was founded in 1964 by the botanists of the Komarov Botanical Institute, St. Petersburg (formerly Leningrad). It represents a continuation of Botanicheskie materialy Instituta Sporovykh Rastenii Glavnogo Botanicheskogo Sada RS FSR, Petrograd, vol. 1–4(7), 1922–1926; Botanicheskie materialy otdela sporovyh rastenii Botanicheskogo Instituta imeni V. L. Komarova Akademii Nauk SSSR, Moscow, Leningrad, vol. 5(4/6)–5(10/12), 1940–1945; vol. 6(7/12)–16, 1950–1963, preceded by Botanicheskie materialy Otdela sporvykh rastenii Botanicheskogo Instituta Akademii Nauk SSSR, Moscow, Leningrad vol. 6(1/6), 1949. The Journal publishes original papers on taxonomy, systematics and biodiversity of algae, fungi, lichens and bryophytes.
