摘要

南极卡多佛拉岛-Andrade, Stchigel, Mac Cormack & Cano从北极斯瓦尔巴群岛领土上的煤矿废料尖端分离出来，以菌株IVA-206为代表。对分离物进行了宏、微观形态学检测，并检测了其内部转录间隔区(ITS1-5.8S-ITS2)和28S rDNA (LSU)的D1/D2区部分序列。分离的C. antarctica IVA-206具有许多特征，使其与来自南极洲的菌株C. antarctica CBS 143035区别开来。北极菌株菌落色素沉着较深，孢子和分生孢子较大，最适生长温度较高。作为我们研究的结果，我们首先发现了微真菌C. antarctica Rodr。——安德拉德、施切格尔、马克·科马克和卡诺在北极。我们的研究表明，C. antarctica Rodr。-Andrade, Stchigel, Mac Cormack & Cano是两极物种，在北极和南极地区都有发现。

First find of Cadophora antarctica Rodr.-Andrade, Stchigel, Mac Cormack & Cano in the Arctic

Cadophora antarctica Rodr.-Andrade, Stchigel, Mac Cormack & Cano was isolated from spoil tip of coal mine in the Arctic, on the territory of the Svalbard archipelago , and is represented by strain IVA-206. Macro- and micromorphology of the isolate were examined along with partial sequences of Internal transcribed spacer rDNA region (ITS1-5.8S-ITS2) and D1/D2 region of 28S rDNA (LSU). The isolate C. antarctica IVA-206 had a number of features that distinguished it from the strain C. antarctica CBS 143035 from Antarctica. Colonies of Arctic strain had darker pigmentation, ramoconidia and conidia were larger, and the optimal growth temperature was higher. As a result of our study, we first discovered the microfungi C. antarctica Rodr.-Andrade, Stchigel, Mac Cormack & Cano in the Arctic. Our study shows that C. antarctica Rodr.-Andrade, Stchigel, Mac Cormack & Cano is a bipolar species found in both the Arctic and Antarctic region.
