The stress response after jasmonic acid (JA) treatment was studied in cell suspension cultures of Catharanthus roseus. The effect of JA on the primary and secondary metabolism was based on changes in profiles of fatty acids (FA) and terpenoid indole alkaloids (TIA). According to multivariate data analyses (MVDA), three major time events were observed and characterized according to the variation...

Pre-tested structured questionnaires were administered to sixty randomly selected respondents; fifty six were appropriately filled and were used for analysis. Data were analyzed using descriptive statistics. The study revealed a greater pe...

The leaves extract of Catharanthus roseus was investigated for hypotensive and hypolipidemic effects in adrenaline-induced hypertensive rats (AIHR) and compared with those of Atenolol in a crossover design. The pharmacologically Active components responsible for hypotensive activities were isolated from plant using bioassay guided purification approach and the structure of the compounds was pro...

This study tracks temporal variations in the habitat use of breeding adult greater flamingos (Phoeni copterus roseus) in the Camargue (southern France) using simultaneous sampling of dN, dC and dS from feather and blood of chicks at fledging. Camargue flamingos forage in a heterogeneous complex of saltpans, permanent and temporary brackish lagoons, freshwater and euryhaline marshes to provision...

Receptor-like kinases (RLKs) are regulators of plant development through allowing cells to sense their extracellular environment. They facilitate detection of local endogenous signals, in addition to external biotic and abiotic stimuli. The Catharanthus roseus RLK1-like (CrRLK1L) protein kinase subfamily, which contains FERONIA, plays a central role in regulating fertilization and in cell expan...

The present investigation was carried out to study the induced mutagenesis of EMS (Ethyl methane sulphonate) on the seed germination, seedling survival and LD50 value of Catharanthus roseus. The seeds of Vinca rosea were treated with different concentration of EMS viz., 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 mM. The untreated seeds were taken as control. The EMS treated and control seeds were...

Catharanthus roseus (L.) which is an important medicinal plant of the family Apocynaceae is used to treat many of the fatal diseases contains a virtual cornucopia of useful alkaloids, used in diabetes, blood pressure, asthma, constipation, and cancer and menetrual problem. There are about two common cultivars of C. roseus which is named on the basis of their flower colour that is the pink flowe...

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...

An investigation has been made about the vesicular arbuscular mycorrhizal fungi colonization in some medicinal plants Catharanthus roseus, C. pusillus, Wrightia tinctoria, Thevetia peruviana, Nerium indicum and Alstonia scholaris belongs to family Apocyanaceae were screened for the occurrence and association of VA mycorrhizal fungi. All the plants screened in the study harbored VA mycorrhizal f...
