  mulberry dwarf disease in guangzhou
     The nucleotide identities were from 83.3% to 99.9% between the detected phytoplasma and others. According to 16S rDNA sequence the phylogenetic tree was constructed. Based on the above results,we deduced that the phytoplasma causes mulberry dwarf disease in Guangzhou belongs to group 16S rⅠ.
     对所得植原体16S rDNA片段进行序列测定,并与其它植物植原体作亲缘关系分析,结果表明该植原体的16S rDNA序列与其它植物病原植原体之间的同源性为83.3%~99.9%,并初步判断所检测到的桑树植原体属于16S rI组。

By polymerase chain reaction (PCR),the seasonal variation of the phytoplasmal amounts in mulberry tree was determined.It was demonstrated that the phytoplasma was unevenly distributed in the host.In stem,its amount increased during the growing season,which reached its peak in July and was undetected in winter;in leaves,the situation was similar to that in stem but the peak was in August.In roots,its amount was lower and hardly varied in all the year round.It was indicated that the seasonal variation of phytoplasma...

By polymerase chain reaction (PCR),the seasonal variation of the phytoplasmal amounts in mulberry tree was determined.It was demonstrated that the phytoplasma was unevenly distributed in the host.In stem,its amount increased during the growing season,which reached its peak in July and was undetected in winter;in leaves,the situation was similar to that in stem but the peak was in August.In roots,its amount was lower and hardly varied in all the year round.It was indicated that the seasonal variation of phytoplasma in mulberry trees was related to that of temperature.

通过聚合酶链式反应(PCR)检测了植原体在桑树体内的分布及其相对含量的周年变化。结果显示,茎部中植原体的含量在生长季节逐渐升高,7月达到最大,而冬季检测不到,叶部与茎部相似但植原体的含量在8月达到最大;根部全年均含有植原体,含量较低。结果表明,桑树植原体在寄主体内的消长与温度的周年变化有关。

Based on the 16S-23S rDNA sequence of phytoplasma,a set of universal primers P1/P7 and a set of nested primers Rm16F2/Rm16R1 were employed to perform nested-PCR detection for pathogenic phytoplasma in mulberry leaf tissues sampled from two variety-collecting bases in Guangzhou,China.It was confirmed that some mulberry varieties in these bases were phytoplasma-infected.The products of nested-PCR,16S rDNA fragments,were then analyzed by restricted fragment length polymorphism with KpnⅠ and MspⅠ and by 6% polyacylamide...

Based on the 16S-23S rDNA sequence of phytoplasma,a set of universal primers P1/P7 and a set of nested primers Rm16F2/Rm16R1 were employed to perform nested-PCR detection for pathogenic phytoplasma in mulberry leaf tissues sampled from two variety-collecting bases in Guangzhou,China.It was confirmed that some mulberry varieties in these bases were phytoplasma-infected.The products of nested-PCR,16S rDNA fragments,were then analyzed by restricted fragment length polymorphism with KpnⅠ and MspⅠ and by 6% polyacylamide gel electrophoresis.The result showed that there were three types of RFLP bands which indicated the diversity of mulberry phytoplasma.The obtained 16S rDNA fragments were sequenced and then compared with the reported phytoplasma 16S rDNA.The nucleotide identities were from 83.3% to 99.9% between the detected phytoplasma and others.According to 16S rDNA sequence the phylogenetic tree was constructed.Based on the above results,we deduced that the phytoplasma causes mulberry dwarf disease in Guangzhou belongs to group 16S rⅠ.

采用植原体16S-23S rDNA区段的通用引物对P1/P7和巢式引物对Rm16F2/Rm16R1,建立了快速准确的桑树植原体巢式PCR检测技术。对广州的两个桑树品种资源圃中的部分桑树品种进行了植原体分子检测,结果在两个资源圃中均发现有植原体存在。对巢式PCR的扩增产物(16S rDNA片段)进行了限制性片断长度多态性(RFLP)分析,显示出3种RFLP带型,暗示桑树植原体存在多样性。对所得植原体16S rDNA片段进行序列测定,并与其它植物植原体作亲缘关系分析,结果表明该植原体的16S rDNA序列与其它植物病原植原体之间的同源性为83.3%~99.9%,并初步判断所检测到的桑树植原体属于16S rI组。
