L. "hairy" roots as a rich source of antioxidants and anti-inflammatory compounds.

The present study aimed to determine the bioactive profile of various extracts of Cichorium intybus L. "hairy" roots. In particular, the total content of flavonoids as well as the reducing power, antioxidant and anti-inflammatory activity of the aqueous and ethanolic (70%) extracts were evaluated.

Biosynthesis of magnetite and cobalt ferrite nanoparticles using extracts of "hairy" roots: preparation, characterization, estimation for environmental remediation and biological application.

The "green" synthesis of magnetite and cobalt ferrite nanoparticles (FeO-NPs and CoFeO-NPs) using extracts of L "hairy" roots was proposed. In particular, the effect and role of important variables in the 'green' synthesis process, including the metal-salt ratio, various counter ions in the reaction mixture, concentration of total flavonoids and reducing power of the extract, were evaluated. The morphology and size distribution of the magnetic nanoparticles (MNPs) depended on the metal oxidation state and ratio of Fe(iii) : Fe(ii) in the initial reaction mixture.

Study of Superoxide Dismutase Activity in Long-Term Cultivated Artemisia and Althaea "hairy" Roots.

The aim of the study was to evaluate the long-term effect of Agrobacterium rhizogenes genes transfer on plant antioxidant system by the study of superoxide dismutase (SOD) activity in "hairy" roots of Artemisia and Althaea spp plants. PCR analyses revealed stability of the transformation and presence of bacterial rol B and rol C genes in the "hairy" roots after 4-6 years from the transformation event. SOD activity in the roots of untransformed in vitro cultivated plants used for the initiation of "hairy" roots growth was in the range of 45.

'Hairy' root extracts as source for 'green' synthesis of silver nanoparticles and medical applications.

The research was focused on the synthesis of silver nanoparticles (AgNPs) using extracts from the "hairy" root cultures of Ledeb. and L. The effect of operational parameters such as type of solvent, temperature of extraction, flavonoids concentration, and reducing power of the wormwood "hairy" root extracts on the particle size and yield of the resultant nanoparticles is reported for the first time.

Agrobacterium rhizogenes-mediated transformation enhances the antioxidant potential of Artemisia tilesii Ledeb.

Plants belonging to the genus Artemisia L. have been used for medicinal purposes since ancient times. These aromatic plants produce and accumulate a wide range of potent secondary metabolites, many of which have shown antioxidant, antiparasitic, antimicrobial, anti-inflammatory, and even anticancer activities.

Functional cybrid plants of Lycopersicon peruvianum var 'dentatum ' with chloroplasts of Lycopersicon esculentum.

 Fertile cybrid plants of three subclones, B1A, B3A, B4A were regenerated from the single colony obtained after the fusion of mesophyll protoplasts of plastome chlorophyll-deficient mutant Lycopersicon peruvianum var 'dentatum' (line 3767) and γ-irradiated mesophyll protoplasts of L. esculentum (cv 'Quedlinburger Frühe Liebe'). Cytogenetic, isozyme, RAPD, morphological and restriction analyses all showed that the subclones had the nuclear genome of L.

Fertile asymmetric somatic hybrids between Lycopersicon esculentum Mill. and Lycopersicon peruvianum var. dentatum Dun.

Thirteen nuclear asymmetric hybrids were regenerated under selective conditions following fusion of chlorophyll-deficient protoplasts from cultivated tomato (Lycopersicon esculentum Mill.) and gamma-irradiated protoplasts from the wild species Lycopersicon peruvianum var. dentatum Dun.

Regeneration of Lycium barbarum L. plants from leaf tissue, callus culture and callus protoplasts.

The possibility of plant regeneration from leaf tissue, callus and callus protoplasts of Lycium barbarum L. has been studied. Leaf segments were cultured on B5 medium (Gamborg et al.
