Abstract

The discharge of phosphorus from abandoned mining sites has resulted in a signifi cant ecological problem within the southern watershed of Dianchi Lake, Yunnan Province, China. The latest research has revealed a signifi cant prevalence of Saccharum rufi pilum in soil contaminated with phosphorus. In our investigation, we isolated an endophytic fungus from the root of Saccharum rufi pilum in an open-pit phosphate mining region in Yunnan, China, and the isolated strain well fi ts the concept of genus Bipolaris (Pleosporaceae). Morphological characteristics combined with the phylogenetic analysis of the internal transcribed spacer (ITS), glyceraldehyde 3-phosphate dehydrogenase (GAPDH), and translation elongation factor 1 alpha (TEF-1α) gene revealed that the fungus is Bipolaris panici-miliacei. This article presents a comprehensive description, a color photo plate and a phylogenetic tree of B. panici-miliacei. This research is valuable for restoring vegetation in abandoned phosphate mining sites.

西南某磷矿废弃地先锋植物(Saccharum rufi pilum)根中新寄主记录

滇池南部流域废弃矿区的磷排放造成了严重的生态问题。最近的研究表明，在受磷污染的土壤中，糖蜜(Saccharum rufi pilum)普遍存在。本研究从云南某露天磷矿地区的糖蜜(Saccharum rufi pilum)根中分离出一株内生真菌，该菌株符合双孢菌属(Pleosporaceae)的概念。形态学特征结合内部转录间隔段(ITS)、甘油醛3-磷酸脱氢酶(GAPDH)和翻译伸长因子1α (TEF-1α)基因的系统发育分析表明，该真菌为双极菌(Bipolaris panicii -miliacei)。本文介绍了一种全面的描述，彩色照片板和系统发育树。该研究对磷矿废弃地植被恢复具有一定的参考价值。

期刊介绍： The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
