Protein "nanoarrays" (March 2002)

Comment ENTRANSFOOD: With the aid of photolithography, miniscule patterns (nanometer-scale) could be created in a thin gold layer. Specific sites for proteins, such as lysozyme, to bind this layer were created. These bound proteins can then be used for studies.

Pork fat modified by spinach transgene (January 2002)

Comment ENTRANSFOOD: According to Japan Times: a Japanese group would have managed to create genetically modified pigs containing a gene from spinach. The aim was to modify the fat composition of pork meat such that unsaturated fats, such as linoleic acid. Such unsaturated fats have presumed health benefits for the consumer.

Rice genome sequenced by Chinese scientists (Jan. 2002)

Comment ENTRANSFOOD: The genome (whole genetic information) of the rice variety Oryza sativa indica has been sequenced by Chinese scientists. Another initiative by other groups to sequence the Oryza sativa japonica variety is still ongoing.

Agrobacterium tumefaciens genome unravelled (December 2001)

Comment ENTRANSFOOD: The genome (whole genetic information) of the bacterium Agrobacterium tumefaciens has been seqeunced. This bacterium causes "crown gall" disease in plants and is able to transmit genetic material to plants. This latter ability has been exploited in the genetic engineering of plants to introduce foreign genetic material into plants with the aid of this bacterium. Two groups of American scientists, which separately performed the same task, both published their results in the scientific journal Science.

Human gene number climbs. New estimate ups our gene number by a third (August 2001).

Instead of the initial estimate of 30,000 genes, the human genome would contain 42,000 genes (Comment ENTRANSFOOD).
