摘要
分离到一株对多种植物具有生理活性的放线菌,为确定其准确的分类地位进行了多相分类学研究。形态特征表明孢子丝螺旋状,孢子球形(单颗)或椭圆形,培养特征和生理生化特性均与丁香暗黄链霉菌相似,16SrRNA基因序列分析表明该放线菌为丁香暗黄链霉菌(Streptomyces lilacinofulvus)。可以预见该放线菌产生的生理活性物质在农作物的栽培上具有广阔的应用前景。
An actinomycete which can produce activity on plants is isolated and studied based on the polyphasic taxonomy. Its morphology study shows that a spore is round or ellipse and a spore chain is spiral. Its cultural, physiological and biochemical characteristics are all similar to Streptomyces lilacinofulvus. The analysis result of 16SrRNA gene sequence indicates that the actinomycete is the known species of Streptomyces lilacinofulvus. It can be well predicted that there is a tremendous prospect of the physiological activity by the actinomycete in cropper growth.
