Globisporangium,特别是G. sylvatium,在各种经济作物中引起毁灭性的根腐病、枯萎病和其他疾病。短句来源为了解木苁蓉在贵州的分布和寄主范围,我们采集了156份根病标本,对病原菌进行了分离,结果表明木苁蓉分布广泛,有11种寄主植物,其中4种是新寄主。此外,为了有效地鉴定G. sylvatium,我们建立了一种简单可靠的基于环介导等温扩增(LAMP)的方法,该方法使用由内部转录间隔序列设计的引物集,具有高特异性和高灵敏度(1 pg/μL)。此外,为了进行田间鉴定,我们采用“Plant-LAMP”方法对9种植物的45份根样品进行了粗DNA提取检测。结果表明,该方法能有效地检测出病根中的木耳菌。因此,我们的研究结果不仅丰富了贵州球孢子囊致病性多样性的现有研究,而且提供了一种高效的LAMP田间检测方法,对植物病害的管理和预防具有重要意义。
Globisporangium, especially G. sylvaticum, causes devastating root rot, blight, and other diseases in various species of cash crops. To investigate the distribution and host range of G. sylvaticum in Guizhou, a suitable habitat for this pathogen, we collected 156 root-diseased samples, isolated the pathogens, and found that G. sylvaticum is widespread and has eleven host plants, including four novel hosts. Furthermore, to effectively identify G. sylvaticum, we developed a simple and dependable method based on loop-mediated isothermal amplification (LAMP), which used a primer set designed from the internal transcribed spacer sequences with high specificity and sensitivity of 1 pg/μL. Additionally, to perform field identification, we used the “Plant-LAMP” method with crude DNA extraction to detect the pathogen in 45 root samples from nine species of plants. Our results showed that this method could effectively detect G. sylvaticum in diseased roots. Therefore, our findings not only enrich existing research on the diversity of pathogenic Globisporangium in Guizhou but also present an efficient LAMP field detection method that could significantly contribute to plant disease management and prevention.
