为明确云南省马铃薯疮痂病病原菌(Streptomyces spp.)的种类及其生物学特征,自2013年从云南省13个马铃薯主产区采集疮痂病病样,共分离到200株链霉菌,通过温室盆栽致病性试验筛选出67株致病菌。通过形态学、生理生化指标、致病性测定及16...为明确云南省马铃薯疮痂病病原菌(Streptomyces spp.)的种类及其生物学特征,自2013年从云南省13个马铃薯主产区采集疮痂病病样,共分离到200株链霉菌,通过温室盆栽致病性试验筛选出67株致病菌。通过形态学、生理生化指标、致病性测定及16S r DNA序列分析对获得的菌株进行鉴定。结果显示,引起云南地区马铃薯疮痂病的病原为10种链霉菌,分别为S.caviscabies、S.anulatus、S.scabies、S.turgidiscabies、S.acidiscabies、S.europaeiscabiei、S.luridiscabiei、S.enissocaesilis、S.griseus和S.aureofaciens。其中S.enissocaesilis和S.anulatus为优势种群,S.caviscabies、S.anulatus和S.luridiscabiei为国内首次报道的病原菌。因此,认为云南省马铃薯疮痂病菌种类复杂多样。展开更多
