| 1 | 昆虫基因组及数据库研究进展显示文摘基因组序列为昆虫分子生物学研究提供丰富的数据资源,推动系统生物学在古老的昆虫学中蓬勃发展。昆虫基因组学研究已经成为当前的研究热点,目前在NCBI登录注册的昆虫基因组测序计划有494项,其中已提交原始测序数据的昆虫有225种,完成基因组拼接的有215种,具有基因注释的有65种,公开发表的昆虫基因组有43篇。本文综述了测序技术发展的历史及其对昆虫基因组研究的推动作用、昆虫基因组的组装和注释及其存在的问题、昆虫基因组测序进展、昆虫基因组数据库的发展及基因数据挖掘利用的基本思路和对策,以及昆虫基因大数据在害虫防治和资源昆虫利用中的应用前景。 | 尹传林 李美珍 贺康 丁思敏 郭殿豪 席羽 李飞 | 2017 | 环境昆虫学报2017，39，1： | 10 |
| 2 | Complete Sequence of pABTJ2, A Plasmid from Acinetobacter baumannii MDR-TJ, Carrying Many Phage-like Elements显示文摘Acinetobacter baumannii is an important opportunistic pathogen in hospital, and the multidrug-resistant isolates of A. baumannii have been increasingly reported in recent years. A number of different mechanisms of resistance have been reported, some of which are associated with plasmid-mediated acquisition of genes. Therefore, studies on plasmids in A. baumannii have been a hot issue lately. We have performed complete genome sequencing of A. baumannii MDR-TJ,which is a multidrug-resistant isolate. Finalizing the remaining large scaffold of the previous assembly, we found a new plasmid pABTJ2, which carries many phage-like elements. The plasmid pABTJ2 is a circular double-stranded DNA molecule, which is 110,967 bp in length. We annotated 125 CDSs from pABTJ2 using IMG ER and ZCURVE_V, accounting for 88.28% of the whole plasmid sequence. Many phage-like elements and a tRNA-coding gene were detected in pABTJ2, which is rarely reported among A. baumannii. The tRNA gene is specific for asparagine codon GTT, which may be a small chromosomal sequence picked up through incorrect excision during plasmid formation. The phage-like elements may have been acquired during the integration process, as the GC content of the region carrying phage-like elements was higher than that of the adjacent regions.The finding of phage-like elements and tRNA-coding gene in pABTJ2 may provide a novel insight into the study of A. baumannii pan-plasmidome. | He Huang Yan Dong Zhi-Liang Yang Hao Luo Xi Zhang Feng Gao | 2014 | Genomics, Proteomics & Bioinformatics2014，12，4： | 2 |
