5-Methyltryptophan resistant cells of Catharanthus roseus.

Selection of Cell Lines of Catharanthus roseus with Increased Tryptophan Decarboxylase Activity

Catharanthus roseus, Cell Suspension C ultures, T ryp tophan A nalogues, R esistant Cell Lines, Tryptophan Decarboxylase, Indole A lkaloids Cell lines o f Catharanthus roseus were selected for resistance to 4 -m ethyltryptophan (4-M T) in order to get strains with increased activities o f tryp tophan decarboxylase (TD C ). This enzym e may exert a decisive regulatory control in indole alkalo id...

Mitotic Block of Human Blood Cells by Vinca herbacea, Catharanthus roseus and Colchicine Alkaloids

Catharanthus roseus (L.) G.Don is a plant which produces anticancer and anti-mitotic indole alkaloids. Colchicine is an anti-mitotic drug. Anti-mitotic effects of Vinca herbacea Waldst. & Kit. indole alkaloids is unknown. The study were evaluated the antimitotic effect of alkaloids of V. herbacea, Catharanthus roseus andcolchicineon mitosis and microtubule arrangement of human blood cells. In t...

Biochemical and Cellular Response of Catharanthus roseus Callus Cells to Cadmium Toxicity

Catharanthus roseus is a medicinal and ornamental plant with growing attention toward its economical value. Cell suspension from C. roseus were treated with 0 to 60mM of cadmium nitrate for 1, 3 and 6 days, then cell viability was determined using trypan blue and MTT assay. Cell morphology was investigated using 0, 10, 30 and 50 mM of cadmium nitrate as selected dose for 3 days. Callus of C.ros...

Adenine Phosphoribosyltransferase Activity in Mitochondria o f Catharanthus roseus Cells

Catharanthus roseus (= Vinca rosea), Adenine Phosphori­ bosyltransferase, Subcellular D istribution, Mitochondria, Purine Salvage Subcellular localization of adenine phosphoribosyltrans­ ferase was examined in Catharanthus roseus cells. At least 13% of the activity was observed in the particulate fraction with the rest observed in the cytosol. Both differential and Percoll density gradient cent...
