    • 摘要: 为了解抗病小麦品种Brock对白粉菌的抗性机制,采用mRNA差异显示技术(DDRT-PCR)和反向Northern杂交技术分析小麦Brock在白粉菌诱导下的差异表达基因.对照组共获得5 072个片段,诱导组获得5 366个片段,反向Northern杂交筛选后,获得94个差异表达片段.基因测序和Blast比对后,共有71个片段得到功能注释,涉及抗病防御相关基因、能量代谢相关基因、转录因子、次级代谢相关基因以及信号转导基因等.选取与RPP13同源的片段7和与MY B44同源的片段10进行半定量表达模式分析,发现白粉菌诱导后这2个基因的表达明显上调,在染菌8 h后达到峰值,表明二者可能参与Brock白粉菌侵染的早期应答反应.

    • 摘要: 以8份芸芥自交亲和系与4份芸芥自交不亲和系为试验材料,通过正交和反交方式共组配了18个不同的杂交组合,调查了F1群体的自交亲和性与否,及1424株F2群体和626株BC1群体的性状分离情况.同时,还采用mRNA差异显示技术研究了芸芥自交亲和基因的表达器官,分离、筛选了与自交亲和性相关的特异基因片段.结果表明:芸芥自交亲和性与细胞质遗传无关,而是由一对核基因控制的简单隐性遗传性状;芸芥自交亲和基因的表达不属于组成性表达,而属于组织特异性表达;在芸芥自交亲和系的柱头cDNA扩增中共得到3条差异cDNA片段,其与芸芥自交亲和基因有密切关系.%18 hybridized combinations were made between 8 self-compatible lines and 4 self-incompatible lines, and inheritance of self-compatibility in E. Sativa Mill was analysed. Furthermore, expresstion tissue of self-compatible genes was preliminary analysed, and specific cDNA fragments related to self-compatibility were isolated and screened by using mRNA differential display technique. The results showed that all the F1 plants were self-incompatible, and the F2 and BC1 population segregated in ratio. Through chi square test, the segregation ratios of self-incompatibility to self-compatibility in F2 and BC| population were coincided with the ratio of 1:3 and 1:1, respectively. Therefore, it was inferred that the hereditary of self-compatibility in Yunjie was controlled by one pair recessive nucleus gene. Self-compatible genes of Yunjie was not constitutive expression, but that belonged to specific tissue expression. Self-compatible lines had 3 differentially expressed bands which exhibited stably with different primers, these cDNA bands were closely related to self-compatibility of Yunjie.

Results 44 differential display bands were found in gene expression between the pistils tissues and the scape tissues of the Lycoris aurea Herb. According to the sequence analysis and homologenous comparison, two of them were confirmed to related with galantamine biosynthesis, one of them was possible related with galantamine transport regulation. Conclusion The three homologous sequences of Lycoris aurea screened by DD-PCR provide strong basis of galantamine synthetic pathways.

    • 摘要: Comparative mRNA expression analysis of the ophthalmoplegia was made between Lantang ( one of the Chinese indigenous pig breeds) and Large White using mRNA differential display technology. Differential expression bands were recycled and re-amplified. Different expressions of five ESTss which were related to the meat quality traits were detected in the two pig breeds. ESTsp7 was expressed higher whereas ESTsp8, ESTsp9, ESTs10 and ESTsp11 were expressed lower in the Large White. Through the NC-BI, it was found that ESTsp7 and cytochrome oxidase subunit M gene in the range of 473 bp had 100% similarity. ESTsp9, ESTsp10, ESTsp11 and pig's SLN(Sarcolipin) gene had 94% -95% similarity. ESTsp8 was not matched with any other genes.%利用mRNA差异显示技术对广东省地方品种蓝塘猪和引进品种大白猪达到经济成熟时的眼肌组织mRNA进行比较分析,并对差异显示条带同收产物进行PCR扩增,检测到与肉质性状相关的5条ESTs在2个猪种中存在表达差异,其中ESTsp7在大白猪种中表达量高,而ESTsp8、ESTsp9、ESTsp10和ESTdp11在蓝塘猪中表达量高于大白猪.通过NCBI检索发现,ESTsp7序列与细胞色素c氧化酶亚单位Ⅲ基因在473 bp的范围内相似性达到100%,ESTsp9、ESTsp10和ESTsp11与猪SLN (Sarcolipin)基因相似性达到了94%~95%,而ESTsp8搜索不到相似基因.

    • 摘要: [目的]探讨mRNA差异显示技术(DDRT)出现假阳性的原因.[方法]以大豆品种"吉林30"和"通农13"为材料,对DDRT分析中造成的假阳性进行了分析.[结果]DDRT假阳性的一个重要来源是由于单引物与cDNA组结合导致非特异性扩增造成的.在DDRT试验中,应平行设置单一引物的PCR试验以校正所得差异片段是否为假阳性或混杂有单引物PCR产物.[结论]为提高DDRT试验成功率奠定了基础.%[ Objective] The aim was to explore the reasons of false positives in Different Display Reverse Transcription (DDRT) analysis.[ Method] Soybean varieties “Jilin 30” and “Tongnong 13” were used as materials to carry out analysis on false positives in DDRT analysis.[ Result] An important origin of false positives appeared in DDRT analysis was the non-specific amplification caused by the combination of single primer and cDNA. The parallel PCR test of single primer should be set so as to verify whether the obtained fragments were the false positives or the PCR productions combined with single primer. [ Conclusion] This study had provided basis for improving the success rate of DDRT experiment.
