The Madagascar periwinkle (Catharanthusroseus in the family Apocynaceae) is an important medicinal plant and is the source of several widely marketed chemotherapeutic drugs. It is also commonly grown for its ornamental values and, due to ease of infection and distinctiveness of symptoms, is often used as the host for studies on phytoplasmas, an important group of uncultivated plant pathogens. T...

The farnesyltransferase α-subunit (FTA) may be involved in the regulation of defence responses against pathogens plants. In this study, gene was amplified from Catharanthus roseus (CrFTA gene). cDNA found to 1 403 bp long, and encodes a putative protein 331 amino acids that contains conserved PPTA motif. phylogenetic analysis showed sequence CrFTA is most similar Coffea canephora. qRT-PCR assay...

This study examines the relation between board characteristics and firm performance among life insurance companies in Thailand. Prior research suggests that boards of directors play a critical role in monitoring non-financial companies in Thailand. However, it is possible that board characteristics are not important in the life insurance industry due to the nature of business and the effect of ...

Knowledge on the biosynthetic pathways of the monoterpene alkaloids is enormous, but little is known about their mechanism of transporting system from the plant cell. There is not concrete evidence confirming the role of ABC transporters in the secretion of monoterpene indole alkaloids (MIAs) in Catharanthus roseus. Therefore, in order to determine the role of different transporting systems inv...

In India, native remedies have been used in diabetes treatment. Plants have always been an ideal source of drugs and many of the plants either directly or indirectly are used to formulate the present available drugs. The present investigation was to find out the antihyperglycemic and antihyperlipidaemic effects of ethanolic leaves extracts of Catharanthus roseus in normal and streptozotocin (ST...

Antitumor substances related to vinblastine and vincristine are exclusively found in the Catharanthus roseus (Madagascar periwinkle), a member of the Apocynaceae plant family, and continue to be extensively used in cancer chemotherapy. Although in high demand, these valuable compounds only accumulate in trace amounts in C. roseus leaves. Vinblastine and vincristine are condensed from the monote...
