Expressed sequence tags analysis revealing the taxonomic position and fatty acid biosynthesis in an oleaginous green microalga, Myrmecia incisa Reisigl (Trebouxiophyceae, Chlorophyta)

cDNA library of Myrmecia incisa H4301 was constructed using λ phage vectors.The library consisted of 1.5×10 6 clones with a recombination rate of 90%,and 1942 clones were randomly sequenced.All 1854 readable expressed sequence tags(ESTs) were clustered into 596 non-redundant sequences(NRSs),among which 126 NRSs were from 1384 ESTs,showing a high redundancy.Among the 596 NRSs,30 were ribosomal RNA,and 152 significantly matched with those available in NCBI database and JGI Genome Portal,the latter were divided into nine subcategories.Overall,59 NRSs were involved in photosynthesis,the respiratory electron transport chain,ATP synthesis,oxidation reduction,fatty acid biosynthesis,glucose metabolism,protein metabolism,and small molecular metabolism,suggesting that these genes were abundantly transcribed during energy and substance metabolism.Acyl-carrier protein,ferrodoxin and fatty acid elongase genes obtained from this cDNA library enabled presumption of a possible biosynthesis pathway of ArA in M.incisa.Codon usage analysis of 142 NRSs with 17798 codons in the predicted coding regions showed that the average G+C content level of the total codons was 55.39%,and that of the third position in base trimers was 66.42%,indicating a strong bias toward cytosine and/or guanosine in this algal genome.Among all synonymous codons,NAG was most favored,while NUA was most avoided.Phylogenic trees inferred from ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit genes and the extra partial sequences of 18S rRNA obtained from this library demonstrated that M.incisa belonged to Trebouxiophyceae and was significantly clustered with M.incisa SAG 2007,Lobosphaera tirolensis,M.bisecta,and Parietochloris incisa,but was clearly distant from P.pseudoalveolaris and P.alveolar.Transmission electron microscopy revealed pyrenoids traversed by many parallel thylakoids membranes,while starch grains were only clearly observed when cells were grown under nitrogen stress.Based on combined investigation of the phylogeny and morphological characteristics,it is proposed that M.incisa be kept in the genus Myrmecia in which there might be two parallel groups,one living freely and another symbiotic species.     

基于MEDL模型的HTML向XML的转换方法

基于MEDL模型提出了一种以内容为导向的,将HTML转换为XML数据的方法.在该方法中,根据网页中值域和属性域的识别,并结合MEDL模型对HTML中的数据进行提取,并将其转换为符合要求的格式.该方法具有提取信息精确、转换格式统一等优点,且具备很好的扩展性,能够为深入开展Web数据挖掘提供很好的支持.     

藏文字库设计中OpenType特征标记的应用研究

基于国际标准实现藏字处理一直是藏文信息处理的难点,OpenType字库的实现解决了该难点,微软Vista操作系统的推出,把藏文等几种少数民族文字的处理推到了一个新的阶段,但Vista自身只带了一个藏文白体字库,不能满足用户对字体的需求。文章分析了OpenType特征标记在藏文字库设计中的应用,有助于设计OpenType藏文字库。     

基于CERNET的高校实验室综合信息系统的设计与实现
