ABSTRACT
Verbascum thapsus L. has extensive pharmacological effects, including antioxidative and antineoplastic action, memory improvement and neuroprotection. However, its phylogenetic position is not established in Scrophulariaceae. In this study, we reported the complete chloroplast genome sequence of V. thapsus L. for the first time and investigate its phylogenetic relationship in Scrophulariaceae. The assembled chloroplast genome is a circular 153,338 bp sequence, including a large single copy (LSC) region of 84,627 bp, a small single copy (SSC) region of 17,829 bp and a pair of inverted repeats (IRs) of 25,441 bp. The genome contains 135 genes, including 86 protein coding genes, 37 tRNA genes, and eight rRNA genes. The phylogenetic tree showed that V. thapsus is closely associated with V. chinense and V. phoeniceum.
ABSTRACT
Gentiana delavayi is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of G. delavayi to investigate its phylogenetic relationship in the family Gentianaceae. The chloroplast genome of G. delavayi was 151,569 bp in length with 37.8% overall GC content, including a large single copy (LSC) region of 81,177 bp, a small single copy (SSC) region of 16,921 bp and a pair of inverted repeats (IRs) of 25,471 bp. The cp genome contained 114 genes, including 78 protein coding genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated G. delavayi was closely related to G. stipitata.
ABSTRACT
Ajuga forrestii is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of A. forrestii to investigate its phylogenetic relationship in the family Lamiaceae. The chloroplast genome of A. forrestii was 150,492 bp in length with 38.3% overall GC content, including a large single copy (LSC) region of 82,148 bp, a small single copy (SSC) region of 17,160 bp and a pair of inverted repeats (IRs) of 25,592 bp. The cp genome contained 112 genes, including 79 protein coding genes, 29 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated Ajuga was closely related to Scutellaria.
ABSTRACT
Paris polyphylla is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of P. polyphylla to investigate its phylogenetic relationship in the genus Paris. The chloroplast genome of P. polyphylla was 163,533 bp in length with 37.1% overall GC content, including a large single copy (LSC) region of 84,272 bp, a small single copy (SSC) region of 12,899 bp and a pair of inverted repeats (IRs) of 33,181 bp. The cp genome contained 114 genes, including 79 protein coding genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated P. polyphylla was closely related to P. marmorata.
ABSTRACT
Paris is a commonly used traditional Chinese medicine (TCM), and has antitumor, antibacterial, sedative, analgesic and hemostatic effects. It has been used as an ingredient of 81 Chinese patent medicines, with a wide application and large market demand. Based on the data retrieved from state Intellectual Property Office patent database, a comprehensive analysis was made on Paris patents, so as to explore the current features of Paris patents in the aspects of domestic patent output, development trend, technology field distribution, time dimension, technology growth rate and patent applicant, and reveal the development trend of China's Paris industry. In addition, based on the current Paris resource application and development, a sustainable, multi-channel and multi-level industrial development approach was built. According to the results, studies of Paris in China are at the rapid development period, with a good development trend. However, because wild Paris resources tend to be exhausted, the studies for artificial cultivation technology should be strengthened to promote the industrial development.
