Comparative analysis of Glycyrrhiza plants based on genotypes and chemical variations

通过对甘草属植物DNA序列和化学成分的比较分析，揭示了甘草属植物的变异特征，甘草是世界上最重要的药用植物之一。根据叶片的DNA序列(PKR型)和化学成分(化学型)，将乌拉尔甘蓝分为中国型和哈萨克斯坦型。PKR基因分型与Guralesis的化学型相关。此外，从甘草种群中筛选出甘草酸高产菌株(T628和01A07-1)和甘草酸缺失菌株(83-555)。

Comparative analysis of Glycyrrhiza plants based on the DNA sequence and chemical constituents were performed to characterize the variation of G. uralensis, which is one of the most important medicinal plants in the world. G.uralensis was divided into the two types, China-type and Kazakstan-type, based on the DNA sequences (pkr genotype) and chemical constituents in the leaves (chemotype). There was correlation between the pkr genotype and chemotype of G.uralesis. Furthermore, high glycyrrhizin-producing strains (T628 and 01A07-1) and a glycyrrhizin-deficient stain (83-555) were selected from the populations of G.uralensis.
