- 摘要:
- 为了解东北地区大豆种子携带病原菌的情况,选取了该地区52个大豆主要品种(系),采用环介导等温扩增技术(loop-mediated isothermal amplification,LAMP)快速检测其种子携带胶孢炭疽菌、平头炭疽菌、冬青丽赤壳菌、亚细亚镰孢菌、黄色镰孢菌、木贼镰孢菌、禾谷镰孢菌、层出镰孢菌、尖镰孢菌、茄腐镰孢菌、轮枝镰孢菌、接骨木镰孢菌、大豆炭腐病菌、大豆拟茎点种腐病菌、大豆疫霉菌和立枯丝核菌16种大豆主要病原菌的状况。结果表明:在其中38个品种(系)的种子样本中累计检测出上述8种病原菌,检出率由高到低依次为:大豆拟茎点种腐病菌、立枯丝核菌、木贼镰孢菌、亚细亚镰孢菌、禾谷镰孢菌、层出镰孢菌、尖镰孢菌和平头炭疽菌。不同大豆品种(系)种子带菌的种类及数量存在较大差异,其中品种绥12-18和29182被检出的病原菌多达4种。本研究对了解东北地区大豆种子携带病原菌的状况有参考价值,并为大豆种子带菌检测提供了新的方法。
- Abstract:
- In order to know the situation of soybean seedborne pathogens in Northeast China, the seeds of 52 major soybean cultivars(lines) collected from this area were analyzed, using loop-mediated isothermal amplification(LAMP) assays for specific detection of 16 known soybean pathogen species, including .Colletotrichum gloeosporioide, C.truncatum, Calonectria ilicicola, Fusarium asiaticum, F.culmorum, F.equiseti, F. graminearum, F. oxysporum, F. proliferatum, F. solani, F. sambucinum, F. verticilliodes, Macrophomina phaseolina, Phomapsis longicolla, Phytophthora sojae, and Rhizoctonia solani. The result showed that there were 38 soybean cultivars(lines) carrying a total of 8 species of seed-borne pathogens, and the most frequent species was Phomapsis longicolla, followed by Rhizoctonia solani, Fusarium equiseti, F. asiaticum, F.graminearum, F. proliferatum, F. oxysporum and Colletotrichum truncatum.The number of detected species in each cultivar of seeds were between 1 and 4.In summary, a simple, rapid, and sensitive method for detecting soybean seed-borne pathogens was developed and successfully used to reveal the situation of soybean seed-borne pathogens in Northeast China.
