【摘要】 <正>由一株链霉菌产生的核苷N9705是肽酰胞嘧啶核苷衍生物,具有广谱抗生活性。N9705能够抑制疱疹病毒Ⅰ型(HSV-I)对Vero细胞、烟草花叶病毒(TMV)对烟叶细胞的病理损伤作用;对四种水稻病原真菌和一种烟草病原真菌有较强的抑制生长作用;还对腐生线虫(P.redivivus)及松材更多还原

【Abstract】 Nucleotide N9705 produced by a strain of Streptomyces is a ramification of peptide -acyl cytosine nucleotides that has a wide range of antibiotic activities.N9705 inhibits the pathogenic damages to Vero cells by HSV-I,and it inhibits the pathogenic damages to tobacco leaf-cells by TMV.Also it can inhibit the growth of four pathogenic fungi from oryzae sativa and one from tobacco.Nucleotide N9705 has nematicidal activities to P.redivivus and B.xylophilus as well.更多还原
