Free radicals play an important role in pathological processes such as aging and developing cancer; hence, natural products inhibit free radical production, and can play an important role in preventing diseases. We aimed to evaluate the scavenging activity of free radicals, reducing power, inhibition of lipid peroxidation and malondialdehyde (MDA) formation, and the antioxidant composition of r...

Portulaca oleracea L. is a medicinal plant find in Europe and Asia. This plant contains valuable secondary metabolite such as noradrenalin. Naturally the wild plant produce small amount of this secondary metabolites so induction of hairy roots can be useful to increase its production. In our research Agrobacterium rhizogenes strain AR15834 was used to induce hairy roots in the two-week leaf exp...

Agrobacterium rhizogenes (pRi), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. In our study four bacterial strains AR15834, A4, 9435 and C318 and three explants types leaf, stems and roots, were examined. Hairy roots were induced from roots, stems and leaf explants. The highest transformation efficiency of 77% was achieved by usi...

The present study deals with the establishment of rolA-transgenic and rolB-transgenic plants for first time through Agrobacterium tumefaciens mediated transformation, exploiting inherent morphogenic potential an important medicinal plant, Bacopa monnieri (L.) Wettst. showed integration expression rolA rolB genes respectively, whereas Ri-transformed rolA, rolB, rolC rolD genes. Morphogenic diffe...

Abstract In April 2019, hydroponically cultivated cucumber plants with characteristic symptoms of crazy root disease were found in two different commercial production greenhouses Poland. Due to excessive and inappropriate growth, this led a reduction yield deterioration the general conditions infected plants. Bacteria isolated from roots subjected morphological evaluation, as well molecular, bi...

This paper presents the map and DNA sequence analysis of pRi8196 transferred DNA (T-DNA) genes encoding root-inducing and mannopine synthesis functions. A canonical 24-base-pair border repeat as well as two "pseudoborders" are present at the functional right T-DNA border. To the left of this border are homologs of the mas1' and mas2' genes of TR pRiA4. Next to these are five open reading frames...

Wild-type potato (Solanum tuberosum L.) plants and their transformants harboring agrobacterial rolB or rolC genes under control of the patatin class I promoter were cultured in vitro. These plants were used as a source of single-node stem cuttings. The structure of native starch in tubers formed on cuttings was determined using methods of X-ray scattering and differential scanning microcalorime...
