Disease resistance results from foreign phytoalexin expression in a novel plant
Article Abstract:
Tobacco plants (Nicotiana tabacum) genetically engineered to express resveratrol, the stilbene-type phytoalexin fungicidal substance, succeeded better than non-transgenic plants in fighting infection by the pathogenic fungus Botrytis cinerea. Stilbene synthase genes that expressed resveratrol were taken from grapevine plants and transfected into tobacco plants. The subsequent improvement in the tobacco plants' disease resistance suggests that genetic manipulation of biosynthetic pathways in plants can make them less susceptible to attack by pathogens.

Twenty-first century crops
Article Abstract:
Genetic engineering has been used to restore the pollen fertility of oilseed rape (Brassica napus), a significant crop species. This is a key advance for researchers who have long been trying to apply transgenes and other genetic engineering methods to improving crop production systems. Now Mariani and colleagues have used a gene construct attached to an anther-specific promoter to a bacterial coding sequence for a ribonuclease to make the oilseed rape fertile. The technique may be useful with other major crops such as maize.

Transgenic crops against parasites
Article Abstract:
Genetically engineered herbicide resistance introduced in commercially viable crops prevents the growth of parasitic flowering plants such as Orobanche and Striga. These target site resistances allow the herbicide from the host plant to move toward underground parasites to alleviate parasitism and to protect and promote crop yield.
