Abstract

Specimens of the rare species Cynodontium suecicum (Rhabdoweisiaceae, Bryophyta) were collected near Drozdovka Bay on the Barents Sea coast of the Kola Peninsula (Russia) in 2016. They were compared with samples of C. suecicum from the Teriberka area (also the coast of the Barents Sea) gathered in 1977 by R. N. Schljakov. The morphological features of both groups of samples were studied, and nucleotide sequence data for ITS1-2 nrDNA and trnL-F cpDNA were obtained. Molecular analysis suggested C. suecicum as a hybrid that inherited cytoplasmic DNA from C. tenellum and nuclear DNA from Kiaeria blyttii. Taking into account the rather clear morphological delimitation against other species, combined with the stability of genetic characters, we believe that S. suecicum should be retained as a species-level taxon.

科拉半岛巴伦支海沿岸一种罕见的苔藓Cynodontium suecicum（Rhabdowisiaceae，Bryophyta）：形态和分子研究

2016年，在科拉半岛（俄罗斯）巴伦支海沿岸的Drozdovka湾附近采集了稀有物种Cyodontium suecicum（Rhabdowisiaceae，Bryophyta）的标本。它们与R.N.Schljakov于1977年采集的Teriberka地区（也是巴伦支海沿岸）的C.suecicum样本进行了比较。研究了两组样品的形态特征，获得了ITS1-2nrDNA和trnL-F cpDNA的核苷酸序列数据。分子分析表明，板蓝草是一个杂交种，其细胞质DNA和细胞核DNA分别继承自柔嫩板蓝草。考虑到与其他物种之间相当清晰的形态学界限，再加上遗传特征的稳定性，我们认为应保留S.suecicum作为一个物种级分类单元。

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.
