大豆是一种能够寄藏间座壳属(Diaporthe)和拟茎点霉属(Phomopsis)病原菌复合体的重要作物,这种复合病原菌侵染体已报道可引起多种大豆病害,包括大豆拟茎点霉属种腐病。该研究采用了大豆拟茎点霉属和间座壳属的2个种病原菌,这2个种分离自大豆植株,并已通过形态学和分子特性鉴定。采用克赫氏法则对大豆幼苗下胚轴致病性进行试验,证明了这2种病菌对大豆具有致病性。大豆拟茎点种腐病菌(Phomops longicolla)在韩国被认为是最常见和致病的病原菌。拟茎点霉属病菌(Phomopsis sp.)作为一个新的大豆病原菌,可能已经被传入到其他植物上,且在中国、日本和葡萄牙该拟茎点霉属病菌的相似菌株能够侵染果 Soybean is an important crop capable of harboring Diaporthe and Phomopsis pathogen complexes that have been reported to cause a wide range of soybean diseases including soybeans Moldy species rot. The study employed two species of pathogenic bacteria from the genera Phytophthora and Syzygium, which were isolated from soybean plants and identified by morphological and molecular characterization. The Koch’s rule was used to test the pathogenicity of hypocotyls of soybean seedlings, which proved that these two pathogenic bacteria were pathogenic to soybean. Soybean Phomops longicolla is considered the most common and pathogenic pathogen in Korea. Phomopsis sp., A new soybean pathogen, may have been introduced into other plants and similar strains of the Phomopsis sp. In China, Japan and Portugal were able to infect fruit
