新型标准化分子克隆技术——Nimble Cloning研发成功

日前,中国热带农业科学院热带生物技术研究所言普副研究员等人经过多年研究,开发了一种新型的标准化分子克隆技术──Nimble Cloning。该技术能将目标DNA通过一步反应直接克隆到环状目标载体。DNA分子克隆技术是分子生物学研究的基础,其创新和发展直接推动着分子生物学的进步。目前使用的分子克隆方法有多种,各有优缺点.

A Nimble Cloning-compatible vector system for high-throughput gene functional analysis in plants

Plant expression vectors are essential tools for gene functional analysis and molecular plant breeding.The gene of interest is transferred to the vector by molecular cloning technology.Nimble Cloning is a newly developed molecular cloning method with the advantages of simplicity,efficiency,and standardization.In this study,we developed a"pNC"vector system that contains 55 Nimble Cloning-compatible vectors for functional analysis of genes in plants.These vectors contain the NC frame flanked by unique adapters for one-step and standardized Nimble Cloning.We demonstrate that the pNC vectors are convenient and effective for the functional analysis of plant genes,including the study of gene ectopic expression,protein subcellular localization,protein-protein interaction,gene silencing(RNAi),virus-induced gene silencing,promoter activity,and CRISPR-Cas9-mediated genome editing.The"pNC"vector system represents a high-throughput toolkit that can facilitate the large-scale analysis of plant functional genomics.

基于Nimble Cloning的新型植物BiFC载体的构建和应用

Nimble Cloning是一项新型的分子克隆技术,具有操作简单、使用灵活、克隆效率高、标准化克隆等优点,但Nimble Cloning需要使用配套的表达载体。本研究将pDOE系列的4个整合型BiFC载体上的SfiI位点去除,然后在这4个载体的多克隆位点处插入NC克隆框,构建了一套适用于Nimble Cloning的新型植物BiFC表达载体,命名为pNC-BiFC-VD系列载体。将pNC-BiFC-VD载体应用到植物蛋白互作研究中,分析了番木瓜eIFiso4E和病毒PRSV的vpg蛋白之间的互作,结果表明番木瓜eIFiso4E和PRSV-vpg在细胞核发生互作。该套新型植物BiFC表达载体有望在植物蛋白互作研究中得到广泛应用。
