摘要
本文报道了一种新的蓝藻属苔藓杆菌(Stigonema lichenoides)， Patova, Novakovskaya, Shalygin et Shadrin, sp. nov.)。样品采集自乌拉尔北部山地冻土带的岩石基质。给出了详细的形态描述，并讨论了本种与有关的Stigonema属分类群的差异。采用16S-23S rRNA序列对所研究样品进行分子系统发育分析。形态学和分子数据的相关性，以及从样本中获得的序列与NCBI数据库中可用数据的比较，使Stigonema属的一个新种得以鉴定。
Stigonema lichenoides sp. nov. (Nostocales, Сyanobacteria): a new species isolated from the lichen Ephebe lanata
A new cyanobacterium species Stigonema lichenoides Patova, Novakovskaya, Shalygin et Shadrin, sp. nov., a photobiont of the cyanolichen Ephebe lanata, has been described. The samples were collected from rocky substrates in the mountain tundra of the Northern Urals. A detailed morphological description is given and differences between this species and related taxa of the genus Stigonema are discussed. A molecular phylogenetic analysis of the studied samples was performed using 16S–23S rRNA sequences. The correlation of morphological and molecular data, as well as the comparison of the sequences obtained from the samples with data available in the NCBI database, allowed the identification of a new species of the genus Stigonema.
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.
