In the research, one kind of guzmania species named ostara was employed to be as material, and the full-length cDNA plasmid library of floral organ was constructed successfully by using SMART technology. The library had 3×10^6 original titer and more than 1 kb insert fragments. After 5'EST sequencing from 2004 positive clone chosen at random and clustering analyse, 1 758 high-quality sequences and 1 365 unigenes including 175 contigs and 1 195 singlets were obtained. These unigenes had 1 283 valid ORFs. COG analysis showed that those proteins coded by EST sequences were divided into 22 classes. Through blast analysis, full length or part cDNA of some genes controlling flower color, development of floral organs, florescence regulation and other breeding value genes were obtained.

本研究以擎天凤梨属品种Ostara为材料，采用SMART技术成功构建了擎天凤梨花器官的质粒型全长cDNA文库，初始文库滴度为3×10^6，插入片段平均长度大于1kb；随机挑取2004个阳性克隆进行5'EST测序，获得高质量序列1758条，经拼接获得1365条单基因簇，其中跨叠群175个和单条序列1195个；经ORF寻找共获得有效ORF1283条；经COG分析EST序列编码的蛋白质被分为22类；经Blast分析后，获得一批花色、花器官发育、花期调控以及其它育种价值基因（包括cDNA全长或片段）。
