| 1 | 人参皂苷生物合成研究进展显示文摘人参为五加科多年生草本植物,驰名中外的名贵药材,人参的主要活性成分为人参皂苷,大体上可以分为3种:齐墩果烷型、原人参二醇(PPD)和原人参三醇(PPT)。人参皂苷具有抗血栓、抗疲劳、抗衰老、控制肿瘤、增强免疫力等诸多作用。关于人参皂苷的研究已深入到药理、药效和生物合成等各个方面,并有很大的提升,该研究对近年来发表的关于人参皂苷生物合成的相关文章进行总结与综述,为人参皂苷的研究提供一定的指导和参考。 | 林彦萍 张美萍 王康宇 孙春玉 王义 | 2016 | 中国中药杂志2016，41，23： | 24 |
| 2 | New Insights into Plant Isoprenoid Metabolism显示文摘Isoprenoids are a hugely diverse family of compounds derived from the C5 precursors isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP).Although all free-living organisms synthesize isoprenoids,they are particularly abundant and diverse in plants,with tens of thousands structures known to date.The highest variety of plant isoprenoids are specialized (secondary) metabolites that participate in the interaction of plants with their environment.These include pigments,volatiles,and defense compounds,some of which have applications in industry and agriculture.For example,isoprenoid drugs are used against cancer (taxol) or malaria (artemisin).But plants also synthesize isoprenoids with essential (primary) functions in respiration (ubiquinone),photosynthesis (carotenoids,chlorophylls,tocopherols,phylIoquinones,plastoquinone),membrane architecture (sterols),and growth regulation (brassinosteroids,cytokinins,gibberellins,abscisic acid,strigolactones).Despite their economic importance and biological relevance,our knowledge of the core pathways for the production of the universal isoprenoid precursors IPP and DMAPP in plant cells remained incomplete until the mid-1990s.Impressive progress in the last decade has resulted in the complete elucidation of several isoprenoid pathways,the identification of regulatory mechanisms,the discovery of new functions and properties of specific isoprenoids,and the successful manipulation of isoprenoid biosynthesis in a number of metabolic engineering approaches.In this update article,we will discuss some of the most recent advances in the plant isoprenoid field,focusing on the pathways supplying the C5 precursors in plant cells and the novel insights into regulatory matters. | Pablo Pulido Catalina Perello Manuel Rodriguez-Concepcion | 2012 | Molecular Plant2012，5，5： | 22 |

| 4 | Genome-wide identification and transcriptional profiling analysis of PIN/PILS auxin transporter gene families in Panax ginseng显示文摘Objective:Plant hormones act as chemical messengers in the regulation of plant development and metabolism.The production of ginsenosides in Panax hybrid is promoted by auxins that are transported and accumulated by PIN-FORMED(PIN)and PIN-LIKES(PILS)auxin transporters.However,genome-wide studies of PIN/PILS of ginseng are still scarce.In current study,identification and transcriptional profiling of PIN/PILS gene families,as well as their potential relationship with ginsenoside biosynthesis in Panax ginseng were investigated.Methods:PIN/PILS genes in P.ginseng was identified via in silico genome-wide analysis,followed by phylogenetic relationships,gene structure,and protein profiles investigation.Moreover,previously reported RNA-sequence data from various tissues and roots after infection were utilized for PIN/PILS genes expression pattern analysis.The Pearson’s correlation analysis of specific PIN/PILS genes expression level and main ginsenoside contents were taken to reveal the potential relationship between auxin transports and ginsenoside biosynthesis in P.ginseng.Results:A genome-wide search of P.ginseng genome for homologous auxin transporter genes identified a total of 17 PIN and 11 PILS genes.Sequence alignment,putative motif organization,and sub-cellular localization indicated redundant and complementary biological functions of these PIN/PILS genes.Most PIN/PILS genes were differentially expressed in a tissue-specific manner,and showed significant correlations with ginsenoside content correspondingly.Eight auxin transporter genes,including both PIN and PILS subfamily members,were positively correlated with ginsenoside content(cor>0.60;P-value<0.05).The expression levels of eleven auxin transporter genes were increased dramatically in the early stage(0–0.5 DPI)after Cylindrocarpon destructans infection,accompanied with various overall expression patterns,implying the dynamic auxin transport in response to biotic stress.Conclusion:Based on the results,we speculate that the accumulation or depletion in temporal or spatial manner of auxin by PIN/PILS transporters involved in the regulation of HMGR activity and subsequent ginsenoside biosynthesis. | Shuiming Xiao Yang Chu Yanjun Chen Qinghe Zhao Baosheng Liao Jingjing Zhang Yuan Gao Jiang Xu Shilin Chen | 2022 | Chinese Herbal Medicines2022，14，1： | 1 |
| 5 | Recent Advances on Key Enzyme Genes in Metabolic Pathways Related to the Synthesis of Aroma Compounds in Tobacco显示文摘This article summarized three main kinds of metabolic pathways related to the synthesis of aroma compounds in plants,concluded the roles and expression patterns of key enzyme genes catalyzing the formation of major intermediate products in phenylpropanoid metabolic pathway,isoprene metabolic pathway and alkaloid biosynthetic pathway respectively,highlighted the latest developments of these key enzyme genes in tobacco,and accordingly proposed that in-depth study at the protein level and analysis of metabolic network interaction should be carried out in tobacco besides the expression regulation and transgenic crop improvement at the genetic level. Based on the above analysis,further improvement of tobacco aroma quality through metabolic engineering and its application prospect in agricultural production were prospected. | Jing LU Guanshan LIU Jiangtao CHAO Yuhe SUN | 2014 | Agricultural Biotechnology2014，3，5： | 1 |
