| 摘 要： | 采用SSH技术分析了VA菌根处理后福鼎大白茶根系基因差异表达情况,获得了差异序列,序列比对显示,在下调表达序列中可能包含了10种未知功能的基因;在上调表达序列中可能包含了5种可能的基因。采用RACE技术获得了Actin基因全长序列,Actin基因长1β606βbp (GenBank, 登录号KJ946252),具有1β131βbp开放阅读框（1st~1β131st）,编码377个氨基酸。分子生物信息学分析表明,Actin蛋白分子量约30.69βkD,等电点为5.27,定位于细胞核等亚细胞区位。研究还显示,Actin在不同品种中表达无显著差异,对非生物性胁迫响应也较弱。

| Abstract: | By using SSH, we analyzed differences in gene expression of root from Fuding white tea infected by VA mycorrhiza and obtained diversity sequences. The sequence alighment showed that the down-regulated expression sequence possibly contained 10 unknown genes and the up-regulated expression sequence possible contained 5 known genes. The Actin genic full-length sequence was obtained by using RACE. The length of Actin gene was 1 606 bp (GenBank Accession No. KJ946252), with 1 131 bp ORF (1st-1 131st), the sequence encoded 377 amino acid. Bioinformatics indicated that the Actin protein’s molecular weight was about 30.69 kD, IEP was 5.27, located in subcellular fraction area like cell nucleus. The study also showed Actin expressed no obvious difference in different cultivars and it responded weak to non-biological stress. |
