摘要
对松萝凤梨(Tillandsia usneoides)开展转录组测序分析,共获得62779条单基因簇(Unigene;4.72Gb)。利用MISA软件筛选出17964个基因内部微卫星(genic SSR)位点,分布于14196条Unigene中,出现频率为28.61%,平均分布距离为7.14kb。优势重复基序为单核苷酸、二核苷酸和三核苷酸,分别占总SSR位点的39.36%、22.30%和29.40%。二核苷酸重复中以AG/CT为优势重复基元,占总位点的17.38%,三核苷酸重复以CCG/CGG和AGG/CCT为主,分别占4.63%和4.41%。对含有genic SSR序列注释发现:3001个Unigenes具有KOG注释;6958个Unigenes具有GO注释;1654个Unigenes具有KEGG直系同源(KO)系统注释。这些Unigenes涉及了许多重要的生物功能和代谢途径,这预示着这些潜在的标记可能与重要的生物功能有关。这些信息将为松萝凤梨分子标记开发以及相关基因组研究奠定基础。
A total of 62779 unigenes(4.72Gb) were obtained by using transcriptome sequenceing analysis in Tillandsia usneoides.A total of 17964 genie simple sequence repeat(genie SSR) loci that occurred in 14196 unigenes were identified by MISA software,and the frequency of these genie SSRs was 28.61%and mean distance was 7.14 kb in the unigenes.Mononucleotide,dinucleotide and trinucleotide were major types,accounting for 39.36%,22.30%and 29.40%,respectively.The dinucleotide repeat motifs of AG/CT were the predominant repeat types(17.38%).The trinucleotide repeat motifs of CCG/CGG and AGG/CCT were the predominant repeat types(4.63%and 4.41%).The unigenes containing genie SSR were annotated by Clusters of Orthologous Groups(COG/KOG),Gene Ontology(GO) database and Kyoto Encyclopedia of Genes and Genomes(KEGG) Orthology(KO) system,respectively.There were 3001 unigenes assigned into KOG classifications.There were 6958 unigenes classified into and GO terms.There were 1654 SSR unigenes involved in KO system.A large number of unigenes were annotated with crucial genes that were associated with important biological functions.The numerous genie SSRs identified in this study will contribute to marker development and research on genomics of T.usneoides.
