Forensic botany II,DNA barcode for land plants: Which markers after the international agreement?

The ambitious idea of using a short piece of DNA for large-scale species identification (DNA barcoding) is already a powerful tool for scientists and the application of this standard technique seems promising in a range of fields including forensic genetics. While DNA barcoding enjoyed a remarkable success for animal identification through cytochrome c oxidase I (COI) analysis, the attempts to identify a single barcode for plants remained a vain hope for a longtime. From the beginning, the Consortium for the Barcode of Life (CBOL) showed a lack of agreement on a core plant barcode, reflecting the diversity of viewpoints. Different research groups advocated various markers with divergent set of criteria until the recent publication by the CBOL–Plant Working Group. After a four-year effort, in 2009 the International Team concluded to agree on standard markers promoting a multilocus solution (rbcL and matK), with 70–75% of discrimination to the species level. In 2009 our group firstly proposed the broad application of DNA barcoding principles as a tool for identification of trace botanical evidence through the analysis of two chloroplast loci (trnH-psbA and trnL-trnF) in plant species belonging to local flora. Difficulties and drawbacks that were encountered included a poor coverage of species in specific databases and the lack of authenticated reference sequences for the selected markers. Successful preliminary results were obtained providing an approach to progressively identify unknown plant specimens to a given taxonomic rank, usable by any non-specialist botanist or in case of a shortage of taxonomic expertise. Now we considered mandatory to update and to compare our previous findings with the new selected plastid markers (matK + rbcL), taking into account forensic requirements.Features of all the four loci (the two previously analyzed trnH-psbA + trnL-trnF and matK + rbcL) were compared singly and in multilocus solutions to assess the most suitable combination for forensic botany.Based on obtained results, we recommend the adoption of a two-locus combination with rbcL + trnH-psbA plastid markers, which currently best satisfies forensic needs for botanical species identification.     

NanoString,a novel digital color-coded barcode technology: current and future applications in molecular diagnostics

Introduction: Formalin-fixed, paraffin-embedded (FFPE) tissue sample is a gold mine of resources for molecular diagnosis and retrospective clinical studies. Although molecular technologies have expanded the range of mutations identified in FFPE samples, the applications of existing technologies are limited by the low nucleic acids yield and poor extraction quality. As a result, the routine clinical applications of molecular diagnosis using FFPE samples has been associated with many practical challenges. NanoString technologies utilize a novel digital color-coded barcode technology based on direct multiplexed measurement of gene expression and offer high levels of precision and sensitivity. Each color-coded barcode is attached to a single target-specific probe corresponding to a single gene which can be individually counted without amplification. Therefore, NanoString is especially useful for measuring gene expression in degraded clinical specimens.

Areas covered: This article describes the applications of NanoString technologies in molecular diagnostics and challenges associated with its applications and the future development.

Expert commentary: Although NanoString technology is still in the early stages of clinical use, it is expected that NanoString-based cancer expression panels would play more important roles in the future in classifying cancer patients and in predicting the response to therapy for better personal therapeutic care.     

基于DNA条形码技术的维吾尔药材桑葚基原鉴定研究

该研究通过分析多途径来源的新疆桑属植物及药材样本的ITS2,psbA-trnH序列,为药材分子鉴定提供依据。以51个新疆桑属植物及药材为样本,对其ITS2,psbA-trnH序列进行PCR扩增和测序,用MEGA 6.0计算其种内、种间Kimura 2-parameter(K2P)距离,分析变异位点,并构建NJ鉴别树。ITS2序列分析结果显示,桑Morus alba、鞑靼桑M.alba var.tatarica、黑桑M.nigra种内无变异;桑与鞑靼桑种间无变异;桑与黑桑种间存在13个变异位点,种间平均KP2遗传距离为0.04;桑与药材样本间无信息变异位点,NJ鉴别树可将桑及鞑靼桑与黑桑区分。psbA-trnH序列分析结果显示,桑与黑桑种内各有1个变异位点,3种植物种间存在插入/缺失变异,可相互区分;种间变异与药材样本内变异一致。因此,ITS2序列可将来源于桑、鞑靼桑的药材样本与黑桑区分,psbA-trnH序列可将来源于三者的药材样本区分,为维吾尔药材真伪鉴别及市场监管提供依据。
