Transcriptome analysis in Catharanthus roseus leaves and roots for comparative terpenoid indole alkaloid profiles.
In Catharanthus roseus (L.) G. Don each tissue is known to produce a distinct spectrum of terpenoid indole alkaloids. Since the invaluable antineoplastic bisindole alkaloids are restricted to the aerial parts of the plant and do not occur in its underground tissues, identification of the structural and regulatory factors operating distinctly in the shoot/leaf of the plant will be a necessity fo...
متن کامل5-Methyltryptophan resistant cells of Catharanthus roseus.
Several cell lines resistant to 5-methyltryptophan were selected from wild type cells of different Catharanthus roseus suspension cultures. The resistant cells had up to 30 times the normal levels of free tryptophan. Despite the increased pool size of tryptophan anthranilate synthetase activity of resistant cells was as sensitive to inhibition by L-tryptophan as wild type cells. The overproduct...
متن کاملThe seco-iridoid pathway from Catharanthus roseus
The (seco)iridoids and their derivatives, the monoterpenoid indole alkaloids (MIAs), form two large families of plant-derived bioactive compounds with a wide spectrum of high-value pharmacological and insect-repellent activities. Vinblastine and vincristine, MIAs used as anticancer drugs, are produced by Catharanthus roseus in extremely low levels, leading to high market prices and poor availab...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
EFFECTS OF DROUGHT STRESS ON THE ALKALOID CONTENTS AND GROWTH PARAMETERS OF Catharanthus roseus
In the present investigation Catharanthus roseus, an important herb used in traditional as well as modern medicine, exposed to water deficit stress and possible changes in chlorophyll contents, photosynthesis rate, transpiration rate, growth parameters as well as total alkaloid content and vincristine and vinblastine levels were studied. Seedlings subjected to 4 different water-regimes. Experim...
