background & aim: investigation of suspension cell culture and callus production in catharanthus roseus. catharanthus roseus is an herbaceous perennial plant belongs to the family apocynaceae. c. roseus is important as commercial medicinal plant because of its alkaloidal content. whole plant contains about 130 alkaloids those are classified as vinca alkaloids. vincristine and vinblastine; t...

background: sugarcane is a monocotyledonous crop that is cultivated in the tropical and subtropical regions of the world. one of the most important criteria, influencing the efficiency of the sugarcane transformation is known to be related to physical and biological factors during the transformation procedure. objectives: the objective of this research was to study the response of callus induc...

The Silybum marianum (L.) Gaertn. is the dicotyledonous herbs of the Asteraceae family that is important in medical industry. The biological active compound of S. marianum is a mixture of several flavonolignals generally known as silymarin. The purpose of this study was to optimize S. marianum tissue culture for callus induction, silymarin production and comparison of some biochemical traits be...

plant tissue culture techniques were used to study the effect of nacl on tropane alkaloids accumulation and proline content of both datura metel and datura stramonium. callus cultures were established for both datura species. however, ms medium supplemented with 1mg/l of both ba and naa was the best for callus production in d. metel, while ms supplemented with 3 mg/l kin and 1 mg/l 2, 4-d was t...

modern biotechnology and genetic engineering using techniques and special ‎laboratory tools plays an important role in the pharmaceutical industry and medicinal ‎plant propagation. among these techniques, it can be noted that a wide range of ‎elicitors are widely used for inducing metabolites at invitro culture. due to the ‎pharmaceutical properties of artichoke and its history, it has been dee...

Agrobacteria mediated Coleus blumei tumour tissues were cultured in vitro on MS medium. Sixteen diversified transformed callus cultures were maintained for several years in the absence of plant growth regulators and antibiotics without affecting the growth rate. Rosmarinic acid was detected spectrophotometrically in all tissue lines but in different quantities. The highest rosmarinic acid accum...

Fresh or dry naked seed-explants of different maturity were cultured in vitro and their responses were investigated on a medium containing 2mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) as growth regulator. It was found that the explants at lower maturity had lower rates of callus induction and lower production of callus masses than those with the more matured ones in the original cultures. Howev...
