摘要:
为筛选对烟草花叶病毒(tobacco mosaic virus,TMV)具有拮抗活性的放线菌,以烤烟Coker 176、K326为材料,采用生物活性测试和半叶枯斑法,测定47株放线菌菌株发酵上清液抗TMV的活性,对具活性的菌株进行分子鉴定和系统发育分析。结果表明,6株放线菌的发酵上清液具有一定的抗TMV活性,其中菌株F187、F349、F417发酵上清液对TMV具有明显钝化作用,发酵上清液与TMV作用30 min后抑制率分别为57.18%、60.27%、70.19%;分子鉴定和系统发育分析显示菌株F187、F417、F349均属链霉菌;链霉菌F187、F349、F417的代谢产物对TMV有较高的抑制活性,值得在菌种鉴定、发酵条件优化、活性物质的分离与鉴定等方面进行深入研究。
