为弄清褐飞虱体内细菌型共生菌的分布状况,采用荧光原位杂交(FISH)技术,用 Cy5标记真细菌16S ribosomal DNA(rDNA)的通用探针 eub338和 non338对细菌型共生菌在褐飞虱体内的分布进行了检测。结果表明:在褐飞虱虫体腹部、产卵管附近以及中场组织附近均检测到 Cy5荧光信号和微弱的自发荧光信号,而反义探针 non338在这些部位均未检测到 Cy5的荧光信号,只检测到自发荧光信号。
為弄清褐飛虱體內細菌型共生菌的分佈狀況,採用熒光原位雜交(FISH)技術,用 Cy5標記真細菌16S ribosomal DNA(rDNA)的通用探針 eub338和 non338對細菌型共生菌在褐飛虱體內的分佈進行瞭檢測。結果錶明:在褐飛虱蟲體腹部、產卵管附近以及中場組織附近均檢測到 Cy5熒光信號和微弱的自髮熒光信號,而反義探針 non338在這些部位均未檢測到 Cy5的熒光信號,隻檢測到自髮熒光信號。

The distribution of bacterial symbionts in brown planthopper was detected by the universal oligo-nucleotide probes eub338 and non338 of Cy5-labeled bacterial 16S rRNA and fluorescence in situ hybridization (FISH).The results showed that Cy5 fluorescence and weak autofluorescence signals were detected in the abdomen,near ovipositor and around midgut of brown planthopper by eub338 but the autofluorescence signal was only detected by antisense probe non338 in the abdomen,around ovipositor and midgut of brown planthopper.
