拟南芥中1个新snoRNA基因的鉴定

摘要

[Objective] To identify a novel snoRNA gene in Arabidopsis thalianan. [Method] Genome sequence of Arabidopsis thalianan was screened by using bioinformatics methods, and the sequence structure, organization form and function of typical candidate gene were analyzed. [Result] The identified snR95 box H/ACA snoRNA had conservative component and structural features of box C/D snoRNA family, possessed two more than 10 nt long rRNA antisense elements. The result revealed that the novel snoRNA is a partial counterpart of the rice Z270, named box C/D snoRNA-AthZ270. [Conclusion] Z270 snoRNA in Arabidopsis thalianan has different function with common snoRNA.
