First nematode-resistance gene found

Article Abstract:

Plant breeder Christian Jung and his colleagues have cloned a gene that makes sugar beet plants resistant to nematodes. This is the first gene identified that makes a plant resistant to an animal pest. The finding could reduce reliance on toxic chemical pesticides or crop rotation to control pests.

Plants as chemical factories

Article Abstract:

Plant genetic engineering has been expanding from exclusively food uses to many non-food products. Innovations include cotton fibers with polymer properties, soaps and detergents from oilseeds such as rapeseed, plastics and biomedical materials.
