[Abstract] microRNA (miRNA) directly associates with its target transcripts (mRNA). This protocol describes a method for detection of direct interaction between miRNA and mRNA. The result of interaction helps screening the specific target mRNAs for a miRNA.
[摘要] microRNA（miRNA）与其目标转录物（mRNA）直接相关。 该方案描述了检测miRNA和mRNA之间直接相互作用的方法。 相互作用的结果有助于筛选miRNA的特异性靶mRNA。
背景 MiRNA是小的非编码调控RNA。 MiRNA通常通过与靶mRNA中的互补序列结合来控制基因表达。 许多生物信息学和计算程序可用于预测miRNA靶标。 但是鉴定miRNA与靶mRNA的直接相关性的实验方法非常有限。 目前的方案可以非常有助于识别miRNA靶标（Phatak等人，2016）。

[Abstract] The CRISPR (clustered regularly interspaced short palindromic repeats)-associated protein 9 (Cas9) has become the most broadly used and powerful tool for genome editing. Many applications of CRISPR-Cas9 require the delivery of multiple small guide RNAs (gRNAs) into the same cell in order to achieve multiplexed gene editing or regulation. Using traditional co-transfection of single gRNA expression vectors, the likelihood of delivering several gRNAs into the same cell decreases in accordance with the number of gRNAs. Thus, we have developed a method to efficiently assemble gRNA expression cassettes (2-30 gRNAs) into one single vector using a Golden-Gate assembly method (Vad-Nielsen et al., 2016). In this protocol, we describe the detailed step-by-step instructions for assembly of ...
[摘要] CRISPR（聚簇定期间隔短回文重复序列）相关蛋白9（Cas9）已成为最广泛使用和强大的基因组编辑工具。 CRISPR-Cas9的许多应用需要将多个小导向RNA（gRNA）递送到相同的细胞中以实现多重基因编辑或调节。使用单个gRNA表达载体的传统共转染，将几个gRNA递送到相同细胞中的可能性根据gRNA的数量减少。因此，我们开发了使用Golden-Gate装配方法（Vad-Nielsen等人，2016）将gRNA表达盒（2-30gRNA）有效地装配到一个单一载体中的方法。在这个协议，我们描述详细的分步指示的多路复用gRNA表达式数组的组装。在我们的表达阵列中使用的gRNA支架是由人U6启动子驱动的来自化脓性链球菌的Cas9蛋白的gRNA 1.0系统。

[Abstract] The genus Lavandula comprises of several economically important lavender species that are mainly cultivated worldwide for essential oil production. Identification of lavender species and their cultivars has been a huge bottleneck in lavender industries due to lack of appropriate identification mechanisms. Recent advances in modern technologies would help to address these identification issues through development of potential molecular markers, including simple sequence repeats (SSRs). SSRs can be developed from specific species, and can be potentially used for related species, which lack the source sequences to develop species-specific SSRs. Here, we describe the guidelines and steps of identifying and analyzing SSRs from expressed sequence tag (EST) sequences of ...
[摘要] 拉丁族 包括几种经济上重要的薰衣草品种，主要在全世界种植精油生产。 由于缺乏适当的鉴定机制，薰衣草物种及其栽培品种的鉴定一直是薰衣草工业的巨大瓶颈。 现代技术的最新进展将有助于通过开发潜在的分子标记物（包括简单序列重复（SSR））来解决这些鉴定问题。 SSR可以从特定物种开发，并且可以潜在地用于相关物种，其缺乏源序列以开发物种特异性SSR。 在这里，我们描述从薰衣草物种的表达序列标签（EST）序列鉴定和分析SSR的指南和步骤。 我们还详细选择EST-SSR在区分源（供体）物种以及相关物种的验证程序。
