Viral diseases are of immense importance considering the extensive damage and severe losses they cause to the crops. Because of their peculiar nature and characteristic association with hosts and vectors, no therapeutic method to completely control them has been found successful. However, certain preventive measures, if adopted suitably can be of great help in avoiding viral diseases. Antiviral...

Plants have been recognized since ancient times as a distinct lineage of organisms, but the precise boundaries of the group have only recently come into sharp focus. Land plants, or embryophytes, are immediately familiar as the organisms that constitute the terrestrial vegetation, dominate agriculture, and play a wide range of cultural and economic roles in human society. It is more difficult t...

We investigated a destructive pathogenic variant of the plant pathogen Ralstonia solanacearum that was consistently isolated in Martinique (French West Indies). Since the 1960s, bacterial wilt of solanaceous crops in Martinique has been caused primarily by strains of R. solanacearum that belong to either phylotype I or phylotype II. Since 1999, anthurium shade houses have been dramatically affe...

CONTEXT Chlordecone, an environmentally persistent organochlorine insecticide used intensively in banana culture in the French West Indies until 1993, has permanently polluted soils and contaminated foodstuffs. Consumption of contaminated food is the main source of exposure nowadays. We sought to identify main contributors to blood chlordecone concentration (BCC) and to validate an exposure ind...

Background & Aim: The present study was to identify the medicinal plant species and introduced as one of the key priority areas for conservation and determination of endangered species were done. Experimental: The method of plant collection in this region was classical method of regional plant taxonomic studies. Collected plants were recognized and determined families, genera and species of th...

This transdisciplinary study has a three-fold systems approach in evaluating a horticultural technology: 1) horticultural evaluations, 2) economic and resource analyses, and 3) systems engineering analyses, using low temperature storage as an example technology. Vegetable grafting is a technique to produce value-added seedlings but requires labor intensive nursery operations. Low temperature st...

to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...

conclusions all plants could inhibit mushroom tyrosinase, but more investigations on human tyrosinase and clinical studies are needed. results the hydroalcoholic extract of p. alkekengi showed the most tyrosinase inhibitory effect with ic50 of 0.09 mg/ml vs. 0.38, 0.38 and 2.82 mg/ml of b. persicum, a. rosea and m. vulgare, respectively. m. vulgare exhibited uncompetitive inhibition and other p...
