The cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Bruchidae), is an important pest of stored cowpea, Vigna ungiculata (L.) Walpers (Fabales: Fabaceae), with ample distribution in tropical and subtropical regions. Many plant essential oils have a broad-spectrum activity against pest insects, and these oils traditionally have been used in the protection of stored products. In this study...

Background: Teucrium persicum, a well-known Iranian endemic plant, has been used to treat various diseases in traditional medicine. Objectives: This study aimed assess the antioxidant and cytotoxic effects of chloroform ethyl acetate extracts T. persicum on cancer cell lines. Methods: The total phenolic flavonoid contents, as well potential were assayed. GC-MS analysis was detect chemical const...

sanguine expectations which were formed with regard to it when first its remarkable effects on the eye became known, the plant itself is undoubtedly destined to become a product of much commercial importance, and already its cultivation, with this view, is being actively prosecuted in Madras and Ceylon. In the botanic gardens of the latter country the coca plant has been growing since 1870, and...

BACKGROUND AND AIMS The nuclear DNA of certain varieties of flax (Linum usitatissimum) can vary within a single generation when the plants are grown under specific environmental conditions. This review details the genomic variations that have been identified and associated with this environmental response. CONCLUSIONS The variation occurs across the whole spectrum of sequence repetition and h...

Cultivated flax (Linum usitatissimum L.) is the earliest oil and fiber crop and its early domestication history may involve multiple events of domestication for oil, fiber, capsular indehiscence, and winter hardiness. Genetic studies have demonstrated that winter cultivated flax is closely related to oil and fiber cultivated flax and shows little relatedness to its progenitor, pale flax (L. bie...

For the first time callus and suspension cultures of Linum mucronatum ssp. annenum were initiated, grown in darkness at 25 degrees C and analyzed for lignans. 6-Methoxypodophyllotoxin was the main lignan besides smaller amounts of podophyllotoxin isolated and identified by chromatographic methods as well as by 1H NMR.
