Genetically modified organisms (GMOs) can be defined as organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally. The technology is often called “modern biotechnology” or “gene technology”, sometimes also “recombinant DNA technology” or “genetic engineering”. It allows selected individual genes to be transferred from one organism into another, also b...

Transgenes encoding for insecticidal crystal (Cry) proteins from the soil-dwelling bacterium Bacillus Thuringiensis have been widely introduced into Genetically Modified (GM) crops to confer protection against insect pests. Concern that these transgenes may also harm beneficial or otherwise valued insects (so-called Non Target Organisms, NTOs) represents a major element of the Environmental Ris...

European Union (EU) policies regarding genetically modified (GM) crops and food have increasingly isolated its member states from much of the rest of the world in this regard over the past decade. The discussion in European countries over whether to grow and eat GM crops and food has stalled plant research, while the rest of the world has been growing and using an increasing number of GM pestor...

Prominent scientists and policymakers assert with confidence that there is no scientific controversy over the health effects of genetically modified organisms (GMOs)—that genetically modified crops currently in commercial use and those yet to be commercialized are inherently safe for human consumption and do not have to be tested. Those who disagree are cast as ‘‘GMO deniers.’’ This article exa...

Pest insects harm crops, livestock and human health, either directly or by acting as vectors of disease. The Sterile Insect Technique (SIT)--mass-release of sterile insects to mate with, and thereby control, their wild counterparts--has been used successfully for decades to control several pest species, including pink bollworm, a lepidopteran pest of cotton. Although it has been suggested that ...

The narrow genetic basis of many crops combined with restrictions on the commercial use of genetically modified plants, has led to a surge of interest in exploring natural biodiversity as a source of novel alleles to improve the productivity, adaptation, quality and nutritional value of crops. Genetic methodologies have been applied to natural variation to improve quality aspects that are assoc...

Genetically engineered crops were first commercialized in 1994 and since then have been rapidly adopted, enabling growers to more effectively manage pests and increase crop productivity while ensuring food, feed, and environmental safety. The development of these crops is complex and based on rigorous science that must be well coordinated to create a plant with desired beneficial phenotypes. Th...

Visit the new GeneWatch UK online database at http://www.genewatch.org In a desperate effort to reverse its failing fortunes, the biotechnology industry and its supporters are putting their faith in the ‘second generation’ of genetically modified (GM) crops. It is claimed that many of these will bring consumer benefits by offering foods with enhanced nutritional value (so-called ‘functional foo...

Why is Europe so critical of GMO crops? As long as it is cheaper to import food than to produce it locally, Western European countries have no need for GMO crops. Where it does matter is Africa. In my scientific opinion, GMO food is safe to eat, GMO crops can increase yield and, when used wisely, are good for the environment. Unfortunately, scientists are helpless in the emotional and political...

Since the beginning of the 90s lots of cationic plant, cysteine-rich antimicrobial peptides (AMP) have been studied. However, Broekaert et al. (1995) only coined the term "plant defensin," after comparison of a new class of plant antifungal peptides with known insect defensins. From there, many plant defensins have been reported and studies on this class of peptides encompass its activity towar...
