Abstract

Cirsium arvense is an important weed in temperate areas, causing yield losses in pasture and cropping systems. Endophytes may affect fungal biocontrol agents deployed to control C. arvense. This was the first study sampling leaves, stems, and roots of C. arvense multiple times in one growing season to determine which endophytic genera were associated with this plant species. Eighty-eight endophytic genera were isolated by culture methods and identified with molecular markers. Sixty-five of these have not previously been reported for C. arvense. This study was the first to document many genera belonging to the orders Pleosporales, Hypocreales, and Diaporthales that have not previously been identified in association with C. arvense. In addition, this study isolated more Leotiomycetes and Helothiales than previous studies on C. arvense endophytes. Information on endophytic genera in C. arvense will aid our understanding of biotic factors influencing fungal biocontrol agents and may improve effectiveness of biocontrol agents.

加利福尼亚蓟（Cirsium arvense (L.) Scop.）的内生菌属

箭毒属（Cirsium arvense）是温带地区的一种重要杂草，会造成牧场和种植系统的产量损失。内生菌可能会影响用于控制箭毒属真菌的生物控制剂。这是首次在一个生长季节多次对枳椇叶、茎和根进行采样，以确定哪些内生菌属与该植物物种有关。通过培养方法分离出了 88 个内生菌属，并用分子标记进行了鉴定。其中 65 个内生菌属以前从未报道过。这项研究首次记录了属于 Pleosporales、Hypocreales 和 Diaporthales 目中的许多菌属，这些菌属以前从未发现与芹菜有关联。此外，与之前对芹菜内生菌的研究相比，这项研究分离出了更多的Leotiomycetes和Helothiales。有关芹菜内生菌属的信息将有助于我们了解影响真菌生物控制剂的生物因素，并可提高生物控制剂的效果。
