In the present study, the effect of different plant growth promoting rhizobacteria (PGPR) like Azospirillum brasilense and Pseudomonas fluorescens on growth parameters and the production of terpenoid indole alkaloids are investigated in two varieties ‘rosea’ and ‘alba’ of Catharanthus roseus. The production of IAA by the PGPR has taken as main criteria in the selection of PGPRs for the seed and...

indole ahloids of vinca species are valued greatly in medical sciences, one reason being for their use as powerful anticancer agents. there are four species of vinca in iran: v. rosea, v. major, v. minor and v. herbacea. in previous investigations, we found that these plants have considerable alkaloid similarity (58.8- 75%). therefore, chromosomic and electrophuretic studies followed after inve...

The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in...

copper is an essential micronutrient for plant growth which is involved in many metabolic processes. however excessive amounts of copper may cause environmental pollution. with an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. the effects of heavy metals on the growth parameter...

Dear Editor, Pityriasis rosea is a common, acute, and self-limiting dermatosis, which is associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7 (1). It predominantly affects individuals of both sexes in their second or third decade of life and is clinically characterized by the occurrence of an initial erythematosquamous plaque followed by the appearance ...

Water soluble cranberry-based phytochemical combinations with oregano, rosemary, and Rhodiola rosea were evaluated for total phenolic content, related antioxidant activity and inhibition of diabetes management-related alpha -glucosidase, pancreatic alpha-amylase inhibition, and hypertension-related ACE-I inhibitory activities. Water extracts of oregano had 114.9 mg/g DW of phenolics which was h...

BACKGROUND Kocuria species are gram-positive, non-pathogenic commensals. However, in immunocompromised patients such as transplant recipients, cancer patients, or patients with chronic medical conditions, they can cause opportunistic infections. CASE PRESENTATION We report the first case of descending necrotizing mediastinitis in a 58-year-old, relatively healthy woman caused by Kocuria rosea...
