Progress of safflower (Carthamus tinctorius L.) regeneration through tissue culture

Background: Safflower regeneration through tissue culture has long been limited to low frequency and lack of an efficient protocol that suitable for most safflower cultivars. In past decades, researches had been carried out to investigate safflower regeneration through tissue culture and great progress had been made. Objective: To investigate factors that affect safflower regeneration through tissue culture principally. Methods: This article summarized available literatures about advancements in safflower regeneration, especially discussed factors affecting safflower tissue culture in detail. Results: Safflower regeneration was fairly hard than other congeneric plants, such as chrysanthemum. The genotype, seedling age, type of explants, medium components, plant growth regulators and other additives all had specific influences on safflower tissue culture. More deepgoing researches need to be undertaken to establish an effective safflower regeneration system.

Color spaces of safflower (Carthamus tinctorius L.) for quality assessment

Objective:In this study,safflower(Carthamus tinctorius L.)was taken as a representative example to examine the application of color characteristics to evaluate quality.Methods:A computer vision system was established for the objective and nondestructive assessment of color using image processing algorithms.Color parameters were investigated based on the RGB,L*a*b and HSV color spaces.The content of hydroxysafflor yellow A(HSYA),a major bioactive constituent of safflower,was determined by high-performance liquid chromatography.The relationship between HSYA content and color values was investigated by Pearson correlation analysis.A multiple linear regression model was established to predict the HSYA content from color values.Results:The red color and lightness of safflower were found to be significantly related to HSYA content.The prediction equation obtained by multiple regression was reliable with an R2 value of 0.805(P<.01).Conclusion:The results suggest that the computer vision technique could be used as a promising and non-destructive technology for color measurement and quality evaluation of CHM.

Safflower (Carthamus Tinctorius L.) a Potential Source of Drugs against Cryptococcal Infections, Malaria and Leishmaniasis

In this research we present that Carthamus Tinctorius L.(gen.Asteraceae,otherwise known as Safflower)(Fig.1)may contain agents active in Cryptococcal infections,malaria and Leishmaniasis,as treatment options are becoming scarce due to drug resistance development.Phytochemistry and pharmacological activities(antimicrobial,antimalarial,antileishmanial)of C.tinctorius L.were analyzed.The composition of volatile oil of safflower dried flowers was analyzed by gas chromatography-mass spectrophotometry with flame ionization detector(GC-FID)and in vitro sensitivity assays were performed to assess biological activity.8 known and 3 unknown compounds were detected in the extract(Fig.1).Then the Safflower ointment was manufactured and its acute toxicity study on rats was tested.The volatile oil of C.tinctorius L exhibited activity against Cryptococcus neoformans,Plasmodium falciparum and Leishmania donovani.Safflower volatile oil has anticryptococcal,antimalarial and antileishmanial effects.The prepared ointment had an excellent acute toxicity safety profile.

Objective:To explore the developmental toxicity and the potential toxicological mechanism of safflower (Carthamus tinctorius L.) on zebrafish embryos/larvae.Methods:Mortality,malformations and increased apoptosis induced by safflower were assessed in zebraflsh embryos from 6 to 96 hours post-fertilization.Enzymes and genes in the anti-oxidative and apoptotic pathways were also assayed.Results:The lethal concentration 50 of safflower to zebrafish embryos was 345.6 mg/L.Hatching inhibition,abnormal spontaneous movement,depressed heart rate,pericardial edema,yolk sac edema,abnormal head-trunk angle,inhibition of melanin release,enlarged yolk,and short body length were observed in safflower-treated zebrafish.Additional apoptotic cells mainly appeared around the heart.Safflower exposure changed the activities of defense enzymes (SOD T,CAT↑,MDA↑,GPX without trend),increased MDA content,decreased caspase-3 activity,and altered mRNA levels of related genes (ogg1 ↓,p53↓,Cu/Zn-sod↑,Mn-sod↓,cat↓,gpx↑).Conclusion:Safflower exhibits developmental toxicity for zebrafish embryos/larvae.The developing heart was speculated as the target organ of toxicity.Oxidative stress and increased apoptosis have roles in the developmental toxicity of safflower.This article provides a novel method to research the teratogenicity and possible mechanisms of toxicity of traditional Chinese medicines that are prohibited or contraindicated in pregnant women.

Molecular mechanism of Salvia miltiorrhiza Bunge and Carthamus tinctorius L. in the treatment of myocardial ischemia based on network pharmacology: a comparative study

Based on network pharmacology and molecular docking technology,the similarities and differences of anti-myocardial ischemia mechanism between Salvia miltiorrhiza Bunge(SM)and Carthamus tinctorius L.(CT)were studied.Firstly,based on the traditional Chinese medicine systems pharmacology(TCMSP),the related compounds of SM and CT were obtained,and the potential targets of these compounds were collected by the target fishing method.Genecards database was used to obtain targets related to myocardial ischemia.The cross targets of CT,SM,and myocardial ischemia were then selected,and the protein-protein interaction(PPI)network was constructed based on the STRING database.The cross targets were imported into the Metascape database for Gene Oncology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.Cytoscape software was used to build the topological network diagram of the drug-compound-target path.Finally,the binding ability of the active ingredient and the key target was verified by molecular docking.65 active ingredients and 38 potential targets were screened from SM,and 22 active ingredients and 58 potential targets were excavated from CT.Important targets common to SM and CT were TNF,IL6,VEGFA,AKT1,etc.The common enrichment pathways involved are fluid shear stress and atherosclerosis,IL-17 signaling pathway,pathways in cancer,and toxoplasmosis.The findings suggested that the two traditional Chinese medicines exerted the effect of myocardial ischemia through the characteristics of multiple targets,multiple pathways,and multiple compounds.

Phosphorus Use Efficiency of Safflower （Carthamus tinctorius L.） and Sunflower （Helianthus annuus L.） Studied in Nutrient Solution

Safflower represents an important oil crop internationally and may have a production potential under low input conditions, but its putatively high phosphorous use efficiency is not sustained. This study aims to directly compare safflower with sunflower in terms of phosphorus use efficiency in nutrient solution under controlled conditions. Growth of both species responded strongly to increasing P supply. Safflower recovers less proportion of added P than sunflower. External P requirement （（g P supply （100 g dry matter （DM） produced）~） was higher in safflower than sunflower. The efficiency of the crops for DM production based on accumulated P （mg P potl, efficiency ratio）, and P concentration in DM （（mg P （g DM）＇I）, utilization index） were interpreted using Michaelis-Menten kinetics as growth response curves. Accordingly, Km constant was lower in sunflower compared to safflower in terms of utilization index, but both were similar in terms of efficiency ratio. High Km constant in safflower in terms of utilization index indicates the high P concentration in tissues to produce 50% of potential maximum DM, consequently less efficient crop. Utilization efficiency contributed more than uptake efficiency in overall PUE in the efficient cultivar and could be the cause of its superiority in PUE. It can be concluded that safflower has a high requirement for P with respect to growth, sunflower is more efficient in terms of uptake and utilization of P at optimal and sub-optimal P supplies indicating that safflower can not be considered a low nutrient input crop compared to sunflower with respect to phosphorus.

Protective effect of Salvia miltiorrhiza and Carthamus tinctorius extract against lipopolysaccharide-induced liver injury

AIM:To investigate the hepatoprotective effects and mechanisms of an extract of Salvia miltiorrhiza and Carthamus tinctorius in vivo.METHODS:C57BL/6J mice were randomly assigned to five groups and intraperitoneally administered 0.9% saline,Salvia miltiorrhiza and Carthamus tinctorius extract [Danhong injection(DHI),0.75 and 3 g/kg mixed extract] or reduced glutathione for injection(RGI,300 mg/kg) for 30 min before exposure to lipopolysaccharide(LPS,16 mg/kg). After intraperitoneal LPS stimulation for 90 min or 6 h,the mice were sacrificed by ether anaesthesia,and serum and liver samples were collected. Histological analysis(H&E) and terminal deoxynucleotidyl transferase-mediated d UTP nick end-labelling(TUNEL) staining were performed. Alanine transferase(ALT),aspartate transaminase(AST),total bilirubin(TBil),glutathione-S-transferase(GST),malondialdehyde(MDA),tumour necrosis factor(TNF)-α,interleukin(IL)-6,and caspase-3 levels were measured. Bax,Bcl-2,P-IκBα,IκBα,P-NF-κB p65,and NF-κB p65 protein levels were determined by Western blot. TNF-α,IL-6,caspase-3,Bax and Bcl-2 m RNA expression was measured by real-time reverse transcription-polymerase chain reaction(RT-PCR).RESULTS:Hematoxylin-eosin staining and TUNEL results suggested that DHI(3 g/kg) treatment alleviated inflammatory and apoptotic(P < 0.01) injury in the liver of mice. DHI treatment dose-dependently blunted the abnormal changes in biochemical parameters such as ALT(72.53 ± 2.83 for 3 g/kg,P < 0.01),AST(76.97 ± 5.00 for 3 g/kg,P < 0.01),TBil(1.17 ± 0.10 for 3 g/kg,P < 0.01),MDA(0.81 ± 0.36 for 3 g/kg,P < 0.01),and GST(358.86 ± 12.09 for 3 g/kg,P < 0.01). Moreover,DHI(3 g/kg) remarkably decreased LPS-induced protein expression of TNF-α(340.55 ± 10.18 for 3 g/kg,P < 0.01),IL-6(261.34 ± 10.18 for 3 g/kg,P < 0.01),and enzyme activity of caspase-3(0.93 ± 0.029 for 3 g/kg,P < 0.01). The LPS-induced m RNA expression of TNF-α,IL-6 and caspase-3 was also decreased by DHI. Western blot analysis revealed that DHI antagonised LPS-stimulated decrease of Bcl-2 and increase of Bax protein expression. Furthermore,DHI inhibited LPS-induced IκBα and NF-κB p65 phosphorylation.CONCLUSION:DHI may be a multi-function protectant against acute hepatic injury in mice through its antiinflammatory,anti-oxidative and anti-apoptotic activities.

Influence of Meta-Topolin on Efficient Plant Regeneration via Micropropagation and Organogenesis of Safflower (<i>Carthamus tinctorius</i>L.) cv. NARI-H-15

The effect of meta-Topolin (mT) was assessed to develop a reliable protocol for efficient plant regeneration of safflower (Carthamus tinctorius L.) cv. NARI-H-15. For micropropagation, 7 - 9 days old shoot-tip explants cultured on MS basal medium supplemented with 3.0 mg/L meta-Topolin (mT) + 0.5 mg/L CPPU showed 97.7% adventitious shoot formation (42.4 shootlets) than node after 45 days of culture. For organogenesis, the seedling explants of immature leaf cultured on 1.5 mg/L CPPU or 1.5 mg/L NAA fortified medium produced high amount of callus than cotyledon and stem calli after 60 days of culture. However, MS basal medium fortified with 4.0 mg/L mT + 1.5 mg/L CPPU was found beneficial to stimulate 100% organogenic response (74.7 shootlets) from immature leaf calli than cotyledon and stem derived calli after 45 days of culture. The healthy plantlets obtained from micropropagation and organogenesis process cultured on 1/4 MS basal salts, 1.5% sucrose (w/v) and 0.8% agar (w/v) medium supplemented with NAA (1.5 mg/L) and mT (0.1 mg/L) produced maximum of 96% (12.8 rootlets) and 84% (7.3 rootlets) adventitious rooting, respectively than mT and CPPU tested medium. However, maximum of 67% and 42% survival rate was noticed when in vitro raised plants from micropropagation and organogenesis were hardened in pots containing soil mix and maintained under green house condition. This optimized regeneration protocol might be helpful in regeneration of new genotypes and cultivars of safflower to improve agronomic traits through in vitro selection process and Agrobacterium-mediated genetic transformation system.

Cloning,expression and activity analysises of chalcone synthase genes in Carthamus tinctorius

Objective:Flavonoids are the bioactive compounds in safflower(Carthamus tinctorius),in which chalcone synthase(CHS)is the first limiting enzyme.However,it is unclear that which chalcone synthase genes(CHSs)are participated in flavonoids biosynthesis in C.tinctorius.In this study,the CHSs in the molecular characterization and enzyme activities were investigated.Methods:Putative chalcone biosynthase genes were screened by the full-length transcriptome sequences data in C.tinctorius.Chalcone biosynthase genes in C.tinctorius(CtCHSs)were cloned from cDNA of flowers of C.tinctorius.The cloned gene sequences were analyzed by bioinformatics,and their expression patterns were analyzed by real-time PCR(RT-PCR).The protein of CtCHS in the development of flowers was detected by polyclonal antibody Western blot.A recombinant vector of CtCHS was constructed.The CtCHS recombinant protein was induced and purified to detect the enzyme reaction(catalyzing the reaction of p-coumaryl-CoA and malonyl-CoA to produce naringin chalcone).The reaction product was detected by HPLC and LC-MS.Results:Two full-length CtCHS genes were successfully cloned from the flowers of safflower(CtCHS1 and CtCHS3),with gene lengths of 1525 bp and 1358 bp,respectively.RT-PCR analysis showed that both genes were highly expressed in the flowers,but the expression of CtCHS1 was higher than that of CtCHS3 at each developmental stage of the flowers.WB analysis showed that only CtCHS1 protein could be detected at each developmental stage of the flowers.HPLC and LC-MS analyses showed that CtCHS1 could catalyze the conversion of p-coumaryl-CoA and malonyl-CoA substrates to naringin chalcone.Conclusion:CtCHS1 is involved in the biosynthesis of naringin chalcone in safflower.
