Objective: Spaceflight has long been perceived as an effective way to improve the quantity and quality of plants with wide applications. In order to obtain stable and inheritable descendants of spaceflightinduced Salvia miltiorrhiza lines, we investigated and analyzed four lines m16, m50, m51, m57(three individuals of each line) and the ground control(three individuals) of the third generation of spaceflight-induced S. miltiorrhiza from primary/secondary metabolism and antioxidative abilities.Methods: A portable photosynthesis system(Li-6400) with red/blue LED light source was used to perform the photosynthetic characteristics to evaluate their primary productivity. The secondary metabolites(phenolic acids, tanshinones, total phenolics and flavonoids) and antioxidant activity of roots were analyzed to assess their quality.Results: Compared with control, line m16 presented weak photosynthetic ability, but high apparent quantum yield(AQY), higher contents of secondary metabolites, and stronger antioxidative abilities.Line m57 had a strong gas exchange ability, relatively higher secondary metabolites contents, and ascending antioxidative abilities. Lines m50 and m51 were in the middle level of lines m16 and m57.The principal component analysis for all the original data revealed three components including a rootrelated index, a leaf-related index, and a CO_(2) response parameter could be used to distinguish spaceflight-induced S. miltiorrhiza lines.Conclusion: Line m57 could be an appropriate material for the investigation of targeted breeding towards high production, and line m16 could be used to identify essential genes and unravel sophisticated pathways underlying the secondary metabolisms.

Magnesium deficiency in plants:An urgent problem

引用

The Crop Journal 2016年第2期4卷 83-91页

作者： Wanli Guo Hussain Nazim zongsuo liang Dongfeng Yang College of Life Science Zhejiang Sci-Tech University Key Laboratory of Plant Secondary Metabolism and Regulation of Zhejiang Province College of Agriculture and Biotechnology Zhejiang University

Although magnesium(Mg) is one of the most important nutrients, involved in many enzyme activities and the structural stabilization of tissues, its importance as a macronutrient ion has been overlooked in recent decades by botanists and agriculturists, who did not regard Mg deficiency(MGD) in plants as a severe health problem. However, recent studies have shown,surprisingly, that Mg contents in historical cereal seeds have markedly declined over time, and two thirds of people surveyed in developed countries received less than their minimum daily Mg requirement. Thus, the mechanisms of response to MGD and ways to increase Mg contents in plants are two urgent practical problems. In this review, we discuss several aspects of MGD in plants, including phenotypic and physiological changes, cell Mg2+homeostasis control by Mg2+transporters, MGD signaling, interactions between Mg2+and other ions, and roles of Mg2+in plant secondary metabolism. Our aim is to improve understanding of the influence of MGD on plant growth and development and to advance crop breeding for Mg enrichment.

Interactions between HLH and bHLH Factors Modulate Light-Regulated Plant Development

Molecular Plant 2012年第3期5卷 688-697页

Phytochromes （Phy） and phytochrome-interacting factor （PIF） transcription factors constitute a major signal- ing module that controls plant development in response to red and far-red light. A low red：far-red ratio is interpreted as shading by neighbor plants and induces cell elongation--a phenomenon called shade-avoidance syndrome （SAS）. PAR1 and its closest homolog PAR2 are negative regulators of SAS; they belong to the HLH transcription factor family that lacks a typical basic domain required for DNA binding, and they are believed to regulate gene expressions through DNA binding transcription factors that are yet to be identified. Here, we show that light signal stabilizes PAR1 protein and PAR1 interacts with PIF4 and inhibits PIF4-mediated gene activation. DNA pull-down and chromatin immunoprecipitation （CHIP） assays showed that PAR1 inhibits PIF4 DNA binding in vitro and in vivo. Transgenic plants overexpressing PAR1 （PARIOX） are insensitive to gibberellin （GA） or high temperature in hypocotyl elongation, similarly to the pifq mutant. In addition to PIF4, PAR1 also interacts with PRE1, a HLH transcription factor activated by brassinosteroid （BR） and GA. Overexpression of PRE1 largely suppressed the dwarf phenotype of PARIOX. These results indicate that PAR1-PRE1 and PAR1-PIF4 het- erodimers form a complex HLH/bHLH network regulating cell elongation and plant development in response to light and hormones.

Andrographis paniculata(A.paniculata)is a Chinese herbal medicine that clears away heat,reduces inflammation,protects the liver,and promotes choleretics.The WRKYs of A.paniculata are still not well characterized,although many WRKYs have been identified in various plant species.In the present study,59 A.paniculata WRKY(ApWRKY)genes were identified and renamed on the basis of their respective chromosome distribution.These ApWRKYs were divided into three groups via phylogenetic analysis according to their WRKY domains and combined with WRKY of Arabidopsis.The 59 identified ApWRKY transcription factors were nonuniformity distributed on 23 chromosomes of A.paniculata.From the structural analysis of the conserved motifs,different ApWRKYs structures showed different biological functions,and the ApWRKY transcription factor had certain species-specificity in the evolutionary process.The expression patterns of the 41 ApWRKYs were examined through quantitative real-time PCR(qRT-PCR)in various tissues and under abiotic stresses(salt).The results showed that most of the ApWRKY had different reactions to salt treatment.In addition,the content of the four main secondary metabolites in A.paniculata leaves was determined under salt stress.The results show that under a low concentration of salt treatment,the synthesis of andrographolide can be improved.

Salvia miltiorrhiza and S.grandifolia are rich in diterpenoids and have therapeutic effects on cardiovascular diseases.In this study,the spatial distribution of diterpenoids in both species was analyzed by a combination of metabolomics and mass spectrometry imaging techniques.The results indicated that diterpenoids in S.miltiorrhiza were mainly abietane-type norditerpenoid quinones with a furan or dihydrofuran D-ring and were mainly distributed in the periderm of the roots,e.***.cryptotanshinone and tanshinone IIA.The compounds in S.grandifolia were mainly phenolic abietane-type tricyclic diterpenoids with six-or seven-membered C-rings,and were widely distributed in the periderm,phloem,and xylem of the roots,e.g.11-hydroxy-sugiol,11,20-dihydroxy-sugiol,and 11,20-dihydroxy-ferruginol.In addition,the leaves of S.grandifolia were rich in tanshinone biosynthesis precursors,such as 11-hydroxy-sugiol,while those of S.miltiorrhiza were rich in phenolic acids.Genes in the upstream pathway of tanshinone biosynthesis were highly expressed in the root of S.grandifolia,and genes in the downstream pathway were highly expressed in the root of S.miltiorrhiza.Here,we describe the specific tissue distributions and mechanisms of diterpenoids in two Salvia species,which will facilitate further investigations of the biosynthesis of diterpenoids in plant synthetic biology.

为探究薇甘菊(Mikania micrantha)叶绿体基因组密码子使用模式和影响其偏好性的主要因素,从NCBI数据库下载并筛选出53条长度大于300 bp的叶绿体蛋白编码基因,采用CodonW 1.4.2、DNASTAR和SPSS 26.0等软件,对其密码子偏好性和成因进行多方面分析。结果表明,薇甘菊叶绿体基因组密码子3个位点的GC平均含量表现为GC1(47.06%)>GC2(39.85%)>GC3(28.16%);GC3含量为17.65%~36.93%。有效密码子数目(ENC)均值远大于35.00,表明密码子偏性较弱。RSCU值大于1.00的密码子有27个,其中第3位碱基使用A或U的密码子占比88.88%,表明薇甘菊密码子第3位碱基偏好使用A或U。中性绘图、ENC-plot和PR2-plot等分析结果表明,在影响薇甘菊密码子偏好性的众多因素中,自然选择发挥主要作用。CAU、ACA和CGU为最优密码子。研究结果可为薇甘菊叶绿体基因组学研究提供参考。
