    In the summer of 2019, a severe stem canker disease affected potato (Solanum tuberosum) plants in a 10-hectare commercial field in Kermanshah province, Iran. Approximately 10% of the plants exhibited wilting, leaf yellowing and brown stem lesions with black sporodochia. Infected plants produced small tubers with no visible lesions. Ten fungal isolates from diseased plants were identified as Paramyrothecium roridum based on colony culture, microscopic chara... ...点击完成人机验证后继续浏览

    2019年夏季,伊朗克尔曼沙省一个10公顷的商业化土豆田(Solanum tuberosum)遭受了一种严重的茎枯病的影响。约有10%的植株表现出萎蔫、叶片变黄以及带有黑色孢子堆的棕色茎部病变的症状。受感染的植株产生的薯块较小,但没有明显的病斑。从患病植物中分离出的十个真菌菌株被鉴定为Paramyrothecium roridum,根据菌落培养、显微镜下特征和内转录间隔区(ITS)区域以及部分β-微管蛋白基因分析得出结论。通过完成柯赫法则确认了P. roridum对幼苗的致病性。寄主范围研究发现该P. roridum分离株具有广泛的致病性,能够成功感染各种植物物种,并表现出不同程度的疾病严重性。Cucumis melo(甜瓜)和Nicotiana rustica(野生烟草)显示出易感性,而Triticum aestivum(小麦)和Avena sativa(燕麦)则表现出抗病性。本研究将P. roridum确定为伊朗土豆茎枯病的新病因。
