Elicitation with middle-viscous chitosan (30 mg/50 mL) significantly stimulated silymarin synthesis in Silybum marianum hairy root cultures. The root cultures established by infection with Agrobacterium rhizogenes AR15834 showed a potential for production of silymarin. Elicitation with medium molecular weight of chitosan (0, 5, 10, 20, and 30 mg/50 mL) was used in order to imp...
Plants remain a major source of new drugs, leads and fine chemicals. Cell cultures deriving from plants offer a fascinating tool to study plant metabolic pathways and offer large scale production systems for valuable compounds - commercial examples include compounds such as paclitaxel. The major constraint with undifferentiated cell cultures is that they are generally considered to be genetical...
Hairy root culture (HRC) represent a valuable biotechnological tool for the production of plant secondary metabolites. Secondary metabolome study Arabidopsis thaliana may help to understand biological roles various metabolites present in it. The work deals with establishment Agrobacterium rhizogenes strains transformed HRC A. very high transformation frequency resulting long term hairy cultures...
An efficient protocol for hairy root induction in Berberis aristata DC. was established using two different strains of Agrobacterium rhizogenes, MTCC 532 and 2364 from IMTECH (Institute of Microbial Technology), Chandigarh, India. The strain 532 was more effective than strain 2364 in hairy root induction and in vitro grown callus (61.11 ± 1.60 % transformation frequency) was found to be suitabl...
Hairy root cultures were obtained from diploid and induced tetraploid plants of Datura stramonium and analyzed by gas chromatography/mass spectrometry. Twenty alkaloids (19 for diploid and 9 for tetraploid hairy root cultures) were identified. A new tropane ester 3-tigloyloxy-6-propionyloxy-7-hydroxytropane was identified on the basis of mass spectral data. Hyoscyamine was the main alkaloid in ...
Opines are low-molecular-weight metabolites specifically biosynthesized by agrobacteria-transformed plant cells when plants struck crown gall and hairy root diseases, which cause uncontrolled tissue overgrowth. Transferred DNA is sustainably incorporated into the genomes of transformed cells, so that opines constitute a persistent biomarker infection pathogenic agrobacteria can be targeted for ...
elicitation with middle-viscous chitosan (30 mg/50 ml) significantly stimulated silymarin synthesis in silybum marianum hairy root cultures. the root cultures established by infection with agrobacterium rhizogenes ar15834 showed a potential for production of silymarin. elicitation with medium molecular weight of chitosan (0, 5, 10, 20, and 30 mg/50 ml) was used in order to improve silymarin pro...
Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...
Genome editing is a valuable technique for gene function analysis and crop improvement. Over the past two years, the CRISPR-Cas9 system has emerged as a powerful tool for precisely targeted gene editing. In this study, we predicted 11 U6 genes in soybean (Glycine max L.). We then constructed two vectors (pCas9-GmU6-sgRNA and pCas9-AtU6-sgRNA) using the soybean U6-10 and Arabidopsis U6-26 promot...
