化学品的可持续生产和通过设计代谢途径来改善这些生物资源，以创建高效的植物生物工厂，取决于对植物中现有化学/生物合成多样性的了解。烟草品种以其对转化和其他新的植物育种技术的适应性而闻名。烟草属主要通过烟草，烟草叶和所有相应的烟草产品的来源而被知道。由于后者的普遍存在，烟草及其近缘种是研究最广泛的植物之一。大多数研究只集中在烟粉菌或其他单个物种上进行化学分型。本研究分析了包含17个烟草种和6个本氏烟草种质的多样性样本，并创建了一个有效代表烟草属化学型核心种质的数据集。利用几个分析平台和以前公布的库/数据库，能够识别和测量各种化学类别的360多种代谢物，以及具有专用光谱和色谱特性的数千种未知物质。编制了烟草属化学型核心种质。所分析的17种烟草的代谢物组成在不同的生长季节都是可重复的，并显示出丰富的化学多样性来源。汇编的数据库对360多种已确认的代谢物和数千种未知的化学特征进行了编目。这些数据突出了高价值化学品和前体含量增加的烟草品种，这些前体以可再生的方式用于高价值化学品的途径工程。
Sustainable production of chemicals and improving these biosources by engineering metabolic pathways to create efficient plant‐based biofactories relies on the knowledge of available chemical/biosynthetic diversity present in the plant. Nicotiana species are well known for their amenability towards transformation and other new plant breeding techniques. The genus Nicotiana is primarily known through Nicotiana tabacum L., the source of tobacco leaves and all respective tobacco products. Due to the prevalence of the latter, N. tabacum and related Nicotiana species are one of the most extensively studied plants. The majority of studies focused solely on N. tabacum or other individual species for chemotyping. The present study analysed a diversity panel including 17 Nicotiana species and six accessions of Nicotiana benthamiana and created a data set that effectively represents the chemotype core collection of the genus Nicotiana. The utilisation of several analytical platforms and previously published libraries/databases enabled the identification and measurement of over 360 metabolites of a wide range of chemical classes as well as thousands of unknowns with dedicated spectral and chromatographic properties. A chemotype core collection for the genus Nicotiana was compiled. The metabolite composition of 17 Nicotiana species analysed was reproducible under different growth seasons and showed a rich source of chemical diversity. The compiled database catalogued over 360 identified metabolites and thousands of unknown chemical features. These data highlight Nicotiana species with enhanced levels of high‐value chemicals and of precursors utilised for pathway engineering of high‐value chemicals in a renewable manner.
