, an important forage legume on China's Qinghai-Tibetan Plateau, exhibited dark-brown sunken lesions on their stems at the Qingyang Experimental Station of Lanzhou University. The fungus isolated from the diseased tissues was identified as via a multi-locus phylogeny (ITS-----). The pathogenicity was confirmed by Koch's postulates. The inoculated plants showed significantly reduced ( < 0.05) growth parameters (height, root length, and biomass), photosynthetic indices (net rate, transpiration, and stomatal conductance), and nutritional quality (crude protein, crude fat, crude ash, and crude fiber) compared to the controls. additionally infected six legume species (, , , , , and ). Optimal in vitro growth occurred on oatmeal agar (mycelium) and cornmeal agar (spores), with D-sucrose and D-peptone as the best carbon and nitrogen sources. This first report of causing anthracnose advances the understanding of legume anthracnose pathogens.
作为中国青藏高原一种重要的豆科牧草，在兰州大学庆阳实验站种植时，其茎上出现了深褐色凹陷病斑。从患病组织中分离出的真菌通过多位点系统发育分析（ITS-----）被鉴定为[具体真菌名称未给出]。通过柯赫氏法则证实了其致病性。与对照相比，接种后的植株在生长参数（株高、根长和生物量）、光合指标（净光合速率、蒸腾速率和气孔导度）以及营养品质（粗蛋白、粗脂肪、粗灰分和粗纤维）方面均显著降低（P < 0.05）。[该真菌名称]还感染了另外六种豆科植物（[具体植物名称未给出]）。在燕麦粉琼脂（菌丝体）和玉米粉琼脂（孢子）上，以D - 蔗糖和D - 蛋白胨作为最佳碳源和氮源时，体外生长最佳。关于[该真菌名称]引起[豆科植物名称未给出]炭疽病的这一首次报道增进了对豆科炭疽病病原体的了解。
